Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

A method for controlling a 360 panoramic system provided in an embodiment of the present application may be applied to a 360 panoramic system. As shown in FIG. 1 , the 360 panoramic system includes a car main control module 110 , a power supply module 120 , a camera controller 130 , a camera 140 and a display screen 150 . The car main control module 110 is connected with the power supply module 120, and the power supply module 120 is respectively connected with the camera controller 130 and the display screen 150. The car main control module 110 supplies power for the camera controller 130 and the display screen 150 by controlling the power supply module 120. The car main control module 110 is also connected to the camera controller 130 and the display screen 150 for data and instruction transmission. The camera controller 130 is connected to the camera 140 and is used for controlling power-on of the camera 140 and performing parameter configuration and synchronous control on the camera 140 .

The following will describe in detail the control method of a 360 panorama system provided by the embodiment of the present application in conjunction with specific implementation methods. Figure 2 is a flow chart of the control method of a 360 panorama system provided by the embodiment of the present application, as shown in Figure 2 As shown, the specific steps are as follows:

In step 201, the car main control module controls the power supply module to supply power to the camera controller.

In practice, the starting method of the 360 panoramic system in the prior art is that when the main control module of the car machine calls the driver of the display screen, it supplies power to the display screen by controlling the power supply module. After the display screen is powered on, when the car machine control module calls the driver of the camera , and then power the camera and configure and communicate with the camera. However, it takes a long time (about 7s) from the start of power supply to the camera getting a stable power-on voltage. During this period, the camera configuration and communication may be due to voltage instability. A problem occurs that causes camera configuration to fail. Therefore, the present application supplies power to the camera controller when the display screen is powered on. Powering the camera controller in advance can ensure that the camera can obtain a stable power-on voltage when the camera driver is subsequently invoked, avoiding camera configuration failures.

Step 202, after a preset power supply stabilization period, the camera controller controls the camera to be powered on, and initializes the camera.

In implementation, after a preset power supply stabilization period (for example, 7s), the camera controller controls the camera to be powered on, and initializes the camera.

Optionally, FIG. 3 is a flowchart of a method for initializing a camera provided in an embodiment of the present application. As shown in FIG. 3 , the specific steps for the camera controller to initialize the camera in step 202 are as follows:

In step 301, the camera controller configures the camera.

In implementation, after the camera is powered on, the camera controller configures the camera.

Optionally, FIG. 4 is a flowchart of a method for configuring a camera by a camera controller provided in an embodiment of the present application. As shown in FIG. 4 , the specific steps for configuring a camera by the camera controller in step 301 are as follows:

Step 401 , the camera controller sends a camera model acquisition command to the camera, and waits for the camera to respond to the camera model acquisition command according to a preset command waiting time.

In implementation, since the camera models and parameters of different manufacturers are not necessarily the same, when the camera controller configures the camera, the camera controller sends a camera model acquiring command to the camera. In the prior art, a command waiting time of 0.5 ms is usually set to wait for the camera to respond to the camera model acquisition command. However, if the command waiting time is too short, occasional timeouts will occur and the camera has not responded, so the camera model cannot be obtained. Therefore, the embodiment of the present application presets a longer command waiting time, so as to avoid the problem that the camera model cannot be obtained occasionally due to a short waiting time.

In step 402, the camera sends the camera model to the camera controller in response to the camera model acquiring instruction.

In implementation, the camera receives a camera model acquiring instruction sent by the camera controller, and each camera sends a corresponding camera model to the camera controller.

Step 403 , the camera controller receives the camera model, queries the target camera parameters corresponding to the camera model in the pre-stored correspondence between the camera model and the camera parameters, and sends a camera configuration command carrying the target camera parameters to the camera.

In implementation, the camera controller receives the camera models sent by each camera, and then inquires the target camera parameters corresponding to the camera models in the pre-stored correspondence between the camera models and camera parameters, and sends the camera a message containing the target camera parameters. Camera configuration instructions.

Step 404, the camera receives the camera configuration instruction, and configures the camera according to the target camera parameters.

In implementation, the camera receives the camera configuration instruction, and configures the camera according to the target camera parameters. For example: camera calibration, camera coordinate transformation, calculation of internal parameters and distortion, and calibration of external parameters and other configuration work.

Optionally, FIG. 5 is a flowchart of another method for configuring a camera by a camera controller provided in an embodiment of the present application. As shown in FIG. 5, if the camera configuration fails, the following steps are performed:

Step 501, if the camera configuration fails, the camera controller repeats the camera configuration step within a preset number of repetitions.

In implementation, the existing 360 panoramic system control method directly performs a black screen display on the display screen area corresponding to the camera configuration failure for the situation that the camera configuration fails. However, in the embodiment of the present application, when the camera configuration fails, the camera controller performs multiple attempts to configure the camera. For example, after the initial configuration failure, the camera controller tries to configure the camera three times to ensure more configuration time. Also, multiple attempts to configure the camera mean that the total amount of command wait time increases. For example, the configuration time for each camera configuration is 20ms. If the configuration is repeated three times, the total configuration time is 60ms, and the camera has enough switching time to ensure successful camera configuration.

Step 502, if the camera configuration fails within the preset number of repetitions, the vehicle main control module controls the display area of the display screen corresponding to the camera to be black.

In the implementation, if multiple attempts to configure the camera still fail, there may be a hardware failure problem. At this time, the main control module of the car controls the display area corresponding to the camera to be black, indicating that the 360 panoramic system needs to be repaired urgently.

Step 503, if the camera configuration is successful within the preset number of repetitions, perform the step of synchronously setting the camera by the camera controller.

In implementation, if the camera configuration is successful within the preset number of repetitions, the camera controller may continue to perform the step of synchronously setting the camera.

Step 302, if the camera is configured successfully, the camera controller performs synchronization settings on the camera.

In the implementation, if the camera is configured successfully, the camera controller will set the camera synchronously to ensure that multiple cameras simultaneously capture the environmental images around the vehicle body, and prevent subsequent image processing from splicing errors caused by out-of-sync images.

Optionally, FIG. 6 is a flowchart of a method for synchronously setting a camera provided in an embodiment of the present application. As shown in FIG. 6 , if the camera is configured successfully in step 302, the camera controller performs specific steps for synchronizing the camera. as follows:

Step 601, the camera controller sends a synchronous trigger signal to the camera.

In implementation, if the camera configuration is successful, the camera controller sends a synchronization trigger signal to the camera.

Step 602, if the camera receives a synchronization trigger signal, then the synchronization setting is successful.

In implementation, if the camera receives a sync trigger signal, the sync setup is successful.

Step 603, if the camera does not receive the synchronization trigger signal, then the synchronization setting fails, and the car main control module controls the display area of the display screen corresponding to the camera to be black.

If the camera does not receive the synchronization trigger signal, then the synchronization setting fails, and the car main control module controls the display area corresponding to the camera to be black.

Step 203, the camera sends the image information of the surrounding environment of the vehicle body to the camera controller.

In implementation, the camera collects the video information of the surrounding environment of the vehicle body, and sends the image information of the surrounding environment of the vehicle body to the camera controller.

Step 204, the camera controller receives the image information and sends it to the vehicle owner control module.

In the implementation, the camera controller receives the image information, performs string operation on the image information, and then sends it to the main control module of the car.

Step 205 , the main control module of the vehicle body receives the image information, and displays the image of the surrounding environment of the vehicle body to the user through the display screen.

In the implementation, the main control module of the car receives the image information after serialization, performs deserialization, and displays the image of the surrounding environment of the vehicle body to the user through the display screen.

Optionally, if the camera controller does not receive image information, perform the following steps:

If the camera controller does not receive the image information, perform the step of the camera controller controlling the camera to be powered on.

In implementation, if the camera controller does not receive the image information, the step of the camera controller controlling the camera to be powered on is performed again.

Optionally, the car main control module is an SC60 module chip, the camera controller is a max9286 deserializer, and the power supply module is a DC-DC circuit.
