Receiving wireless signal information uploaded by the collecting end, where the wireless signal information includes first wireless signal information and second wireless signal information;

Generating a corresponding fingerprint information to be verified based on the first wireless signal information and an area name of the collection area, and saving the to-be-checked fingerprint information to the wireless signal fingerprint database;

In this embodiment, the method for calibrating the room wireless signal fingerprint information is applied to a server, such as the server shown in FIG. The server receives the wireless signal information uploaded by the collecting end to obtain a part of the wireless signal information, generates the wireless signal fingerprint information as the to-be-checked fingerprint information, and acquires another part of the wireless signal information for verification.

Referring to FIG. 2, the following is a specific step of implementing a calibration method for wireless signal fingerprint information in this embodiment:

Step S10: Receive wireless signal information uploaded by the collecting end, where the wireless signal information includes first wireless signal information and second wireless signal information.

The communication connection between the server and the collection end, when the user at the collection end reaches the collection location, uploads the live image to the server, and the server determines the acquisition frequency based on the real image to receive the preset frequency (preset frequency: set according to actual conditions) The factors affecting the preset frequency include: the size of the collection area, the amount of wireless information to be collected, and the moving speed of the collection end. In this embodiment, the preset frequency can be 1 second each time, that is, the acquisition end every second. The wireless signal information is uploaded once. If the moving speed of the collecting end is 1 meter per second, one wireless signal information is collected every one meter. The wireless signal information includes the first wireless signal information and the second wireless signal information.

The server may divide the received wireless signal into the first wireless signal information and the second wireless signal information in the following manner, for example:

Step a: determining, according to the real-life image, that the collection end is in the collection area, receiving wireless signal information uploaded by the preset frequency acquisition end, to generate a wireless signal information set;

Step b: dividing the wireless signal information set into two subsets with the same number of signals, and using the wireless signal information in one subset as the first wireless signal information, and the wireless signal information in the other subset as the second wireless signal information. .

Specifically, the server will receive the wireless signal, and divide the wireless signal information set into two subsets with the same number of signals: so that the server generates the to-be-verified fingerprint information by using the wireless signals in one of the subsets; Wireless signal information is used for verification. Such a method can ensure that the verification of wireless signal information is more accurate and scientific.

Step S20: Generate corresponding to-be-checked fingerprint information based on the first wireless signal information and the area name of the collection area, and save the to-be-checked fingerprint information to the wireless signal fingerprint database.

In this embodiment, the server records the location of each signal source included in the indoor environment of the collection area, wherein the signal source is used to transmit a wireless signal to collect wireless signal information; and then record each signal source included in the indoor location distribution of the collection area. The server generates wireless signal information (wireless signal information including detection of each signal source, signal identifier corresponding to the signal source, and corresponding signal strength) and the area name of the collection area, and generates corresponding fingerprint information to be verified. That is, the received signal strength and the signal identifier of the signal source are stored in association with each location corresponding to the region name distribution, and the wireless signal fingerprint is generated based on the associated stored location information, signal identifier, and signal strength, and the wireless signal fingerprint is generated as the to-be-verified The fingerprint information is saved and the fingerprint information to be verified is saved in the wireless signal fingerprint database.

In the implementation of the wireless signal fingerprint information generation and verification to the wireless fingerprint information database, the server first records the location of each signal source, wherein the location of each signal source can be collected by the collection terminal and uploaded to the server. After recording the positions of the respective signal sources, the server records the signal strength of each signal source detected at each position in the indoor position distribution of the collection area. It should be noted that since the indoor position distribution includes multiple signal source packages, each of them There are also multiple signal sources detected by the position. Correspondingly, the signal strength recorded in each position also includes multiple.

Step S30, traversing and matching the second wireless signal information and the wireless signal fingerprint database to determine whether the fingerprint information to be verified is valid.

The second wireless signal information received by the server is matched with the preset wireless signal fingerprint database, that is, the second wireless signal information is traversed in the wireless signal fingerprint database to determine an indoor location corresponding to the second wireless signal information. (The indoor position can be understood as the position corresponding to the area name of the collection area), and it is determined whether the indoor location corresponding to the second wireless signal information and the indoor location corresponding to the verification fingerprint information are the same. If the same, the fingerprint information to be verified is valid. On the other hand, if it is different, the fingerprint information to be verified is invalid.

Step S40: If the fingerprint information to be verified is invalid, the fingerprint information to be verified is removed from the wireless signal fingerprint database to perform re-acquisition of the wireless signal information.

If the fingerprint information to be verified is invalid, the server removes the fingerprint information to be verified from the wireless signal fingerprint database, and sends the prompt information to the collecting end, so that the user of the collecting end performs the re-acquisition of the wireless signal information.

In this embodiment, the technical solution of the present invention generates edge verification during the process of generating fingerprint information of the wireless signal information, and removes the invalid fingerprint information, instead of discovering the problem during the use of the user and then performing wireless signal information. Collecting again, this method increases the accuracy of wireless signal information collection, avoids secondary acquisition, improves the efficiency of wireless signal information collection, reduces the waste of human resources, and reduces the acquisition cost.

The present invention further proposes the embodiment based on the first embodiment. This embodiment is a refinement of step S30:

In step S30, the second wireless signal information is traversed and matched with the wireless signal fingerprint database to determine whether the fingerprint information to be verified is valid; the following two methods may be used:

Referring to FIG. 3, mode 1: comparing the indoor location corresponding to the second wireless signal information with the verification location in the fingerprint information to be verified, to determine whether the fingerprint information to be verified is valid, including the following steps:

Step S31, extracting a signal feature value from the second wireless signal information, and performing traversal matching on the feature value and the wireless signal fingerprint database to determine an indoor location corresponding to the second wireless signal information;

Step S32, comparing the indoor location with the verification location in the fingerprint information to be verified;

Step S33, if the indoor location matches the verification location, the fingerprint information to be verified is valid.

Step S34: If the indoor location does not match the verification location, the fingerprint information to be verified is invalid.

Specifically, the second wireless signal information is used to extract a signal feature value (feature value: the feature value generated according to the signal strength, the signal identifier, and the indoor location corresponding to the signal, which may be data encoding, or may be other unique. The identification information may be that the plurality of wireless signal information generates a signature code, or a wireless signal information generates a signature code, and the feature value is traversed and matched with the wireless signal fingerprint database to determine the second wireless signal information. Corresponding indoor location server acquires a signal identifier and a signal strength in the second wireless signal information, and in the wireless signal fingerprint database, searches for a signal source location corresponding to the signal identifier, and determines an indoor location corresponding to the second wireless signal information, That is, the server determines the signal identifier corresponding to the received second wireless signal information, compares the determined signal identifier with the wireless signal fingerprint database, determines whether the wireless signal fingerprint database matches the wireless signal information, and determines the wireless signal. Basic signal information in the fingerprint library that matches the signal identifier Determining an indoor location corresponding to the signal identifier of the wireless signal information based on a mapping relationship between the basic signal information and the indoor location in the wireless signal fingerprint database; comparing the indoor location with the verification location in the to-be-checked fingerprint information, To determine whether the same is the same; if the same, the fingerprint information to be verified is valid, and if not, the fingerprint information to be verified is invalid.

Referring to FIG. 4, method 2: comparing the feature value extracted in the second wireless signal information with the verification location in the to-be-checked fingerprint information to determine whether the fingerprint information to be verified is valid, including the following steps:

Step S35, extracting the feature value from the second wireless signal information, and traversing and matching the feature value with the wireless signal fingerprint database;

Step S36, comparing the feature value with a check feature value of the fingerprint information to be verified;

Step S37: If the similarity between the feature value and the check feature value of the to-be-checked fingerprint information is greater than a preset value, the fingerprint information to be verified is valid.

Step S38: If the similarity between the feature value and the check feature value of the to-be-checked fingerprint information is less than or equal to a preset value, the fingerprint information to be verified is invalid.

Specifically, the second wireless signal information is extracted, and the feature value is traversed and matched with the wireless signal fingerprint database; that is, the feature value generated by the different wireless signal information is stored in the wireless signal fingerprint database, and the second Comparing the feature value generated by the wireless signal with the check feature value of the fingerprint information to be verified, if the similarity between the feature value and the check feature value of the to-be-checked fingerprint information is greater than a preset value (preset Value: can be determined according to the number of wireless signal information, the preset value can be set to 85%), the fingerprint information to be verified is valid, if the feature value is similar to the check feature value of the fingerprint information to be verified If the degree is less than or equal to the preset value, the fingerprint information to be verified is invalid.

In this embodiment, two ways of signal matching identification are specifically given, one of which is to determine whether the indoor location determines whether the fingerprint information to be verified is valid, and the other is to compare the signature information by comparing the signature information. It is effective, and its essence is determined by the comparison of wireless signals. In this embodiment, two specific comparison methods are proposed. The actual comparison method is not limited to these two methods, and the same or equivalent replacements are It should be counted as the scope of the claimed invention.

In this embodiment, the generated wireless signal fingerprint information is verified to ensure the accuracy of wireless information collection.

Referring to FIG. 5, on the basis of the first embodiment of the present invention, the present invention further provides a second embodiment. In the second embodiment, when the fingerprint information to be verified is valid, the following steps are further included:

Step S50, if the fingerprint information to be verified is valid, adding the second wireless signal information to the wireless signal fingerprint database;

Step S60: Generate new fingerprint information based on the to-be-checked fingerprint information and the second wireless signal information.

And if the server determines that the fingerprint information to be verified is valid, adding the second wireless signal information to the wireless signal fingerprint database; and generating new fingerprint information based on the to-be-checked fingerprint information and the second wireless signal information, ie, The new fingerprint information is generated by processing the fingerprint information to be verified and the second wireless signal information according to a certain algorithm, and may be a feature value or the like.

In the embodiment, when the server determines that the fingerprint information to be verified is valid, the second wireless signal information is added to the wireless signal fingerprint database, so that the amount of information in the wireless signal fingerprint database is larger, thereby making the positioning based on the wireless signal fingerprint more Accurately, at the same time, the fingerprint information to be verified and the second wireless signal information are collated, and the wireless signal fingerprint information in the wireless signal fingerprint database is adjusted, so that the wireless signal fingerprint information is more accurate.

Further, referring to FIG. 6, in the embodiment, the number of verifications is improved, and the multiple verification is avoided. In the third embodiment of the method for calibrating the wireless signal fingerprint information of the present invention, the wireless signal fingerprint information is used. The calibration methods include:

Step S70: The number of verifications of the fingerprint information to be verified is counted, and the number of verifications of the fingerprint information to be verified exceeds a threshold.

The server counts the number of verifications of the fingerprint information to be verified, and determines that the number of verifications of the to-be-checked fingerprint information exceeds a threshold (threshold value: the threshold value may be set according to a specific situation, and the purpose of setting the purpose is to prevent the collection end from performing multiple acquisitions, thereby making Less efficient).

Step S80: If the number of times of verification of the fingerprint information to be verified exceeds a threshold, the preset frequency is adjusted to perform adjustment of the collection position in the collection area.

If the number of verifications of the fingerprint information to be verified exceeds the threshold, the preset frequency is adjusted, and the supplementary explanation is required. The purpose of adjusting the preset frequency is to change the frequency (for example, the acquisition end according to a fixed speed, route) Move, adjust the preset acquisition frequency to achieve the purpose of adjusting the position of the collection point), adjust the position of the collection point, the server can plan the acquisition route when collecting, that is, the server can adjust the acquisition route and adjust the acquisition frequency, so that The wireless signal collected at the acquisition end is more accurate.

In the embodiment, when the server verifies that the fingerprint information to be verified is invalid multiple times, the server may adjust the frequency of the wireless signal transmitted by the collecting end through the communication connection, thereby adjusting the position of the collection point, so that the collection of the wireless signal information is more efficient and avoids The acquisition is inaccurate due to multiple acquisitions.
