Based on the embodiments of the present application, when the user uses the mobile phone to shoot horizontally, the mobile phone automatically saves the photographed photo in the direction most suitable for the user to read, thereby avoiding the mobile phone from saving the photo direction by mistake, and does not require the user to manually adjust, thereby improving the user experience.

FIG. 8 is an exemplary flowchart of a method for saving an image according to an embodiment of the present application. As shown in FIG. 8 , the method may include steps 301 to 305 .

302. Input the photographed photo into the image rotation direction recognition model.

Optionally, when the mobile phone determines that the angle between the mobile phone panel and the horizontal plane satisfies a preset value, the mobile phone inputs the photographed photo into the image rotation direction recognition model. The plane on which the panel of the mobile phone is located is parallel to the plane on which the upper surface of the mobile phone is located.

The gravity sensor in the mobile phone can obtain the upward gravitational acceleration value of the X axis (for example, the bottom direction of the mobile phone) and the Y axis (for example, the side direction of the mobile phone) of the mobile phone panel, and the plane formed by the X axis and the Y axis is the mobile phone panel. the plane on which it is located. If the gravitational acceleration value on the X-axis is less than the first preset acceleration value, and the gravitational acceleration value on the Y-axis is less than the second preset acceleration value, it can be determined that the angle of the plane where the phone panel is located deviates from the horizontal plane is within the preset range Inside, that is, the plane where the mobile phone panel is located is nearly parallel to the horizontal plane. At this time, it can be determined that the user is using the mobile phone to shoot horizontally.

When the user shoots horizontally, the photos taken may be saved in the wrong direction. At this time, the photos taken by the user are input into the pre-trained image rotation direction recognition model. The image rotation direction recognition model can output multiple A result, for example, forward photo, rotate 90 degrees clockwise, rotate 180 degrees clockwise, rotate 270 degrees clockwise, etc.

The training method of the image rotation direction recognition model is as follows:

(1) Obtain a labeled training data set.

Exemplarily, a large number of forward (rotation angle is 0) sample photos can be obtained, and the sample photos can be rotated clockwise by 90 degrees, 180 degrees, and 270 degrees respectively, and saved, to obtain photos in four directions.

Exemplarily, a large number of sample photos in the forward direction (rotation angle is 0) can be obtained, and the sample photos can be rotated clockwise by 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees respectively and saved. , to get photos in eight directions.

It should be understood that in the embodiment of the present application, sample photos in more directions may also be stored, and the sample photos may also be rotated counterclockwise and stored, which is not specifically limited in the embodiment of the present application.

Each sample photo and the photos in multiple directions saved after rotation form a sample training data set to obtain multiple training sets;

The photos in different directions in each training set are marked with data to obtain each marked training set. For example, if each training set includes the above four sample photos in different directions, the forward photos in each training set are marked as "0", the photos rotated 90 degrees clockwise are marked as "1", and the clockwise photos are marked as "1". 180-degree photos are marked as "2", and photos rotated 90 degrees clockwise are marked as "3", resulting in a labeled training dataset.

(2) Input the labeled training data set into the neural network model for training.

It should be understood that the neural network model can be a convolutional neural network (CNN), a deep belief network (DBN), a recurrent neural network (RNN), a generative adversarial network, GAN), etc., which are not specifically limited in the embodiments of the present application.

For example, if the neural network model is a CNN, the labeled training data set in step (1) can be input into the CNN model for training.

(3), obtain the image rotation direction recognition model.

Wherein, in step (2), when the loss function of the CNN model is minimized and kept stable, the trained CNN image rotation direction recognition model can be obtained.

303. According to the output result of the image rotation direction recognition model, rotate the picture and save it.

For example, if the training data set of the image rotation direction recognition model includes four sample photos in different directions, the image rotation direction recognition model can output four results. Rotate the clockwise angle of the photo, and then rotate the currently shot photo counterclockwise at the same angle and save it, or rotate the currently shot photo clockwise by a certain angle to the positive direction.

Exemplarily, as shown in FIG. 7 , the output result of the image rotation direction recognition model shows that the clockwise rotation angle of the current photo relative to the forward photo is 90 degrees, then the currently captured photo is rotated 90 degrees counterclockwise and saved. in the album.

Exemplarily, if the output result of the image rotation direction recognition model shows that the clockwise rotation angle of the current photo relative to the forward photo is 90 degrees, the currently captured photo is rotated 270 degrees clockwise and saved in the album.

Optionally, the currently taken photos can be rotated 90 degrees, 180 degrees, and 270 degrees clockwise respectively and then input into the conventional CNN target recognition model to obtain four confidence results, and save the photo with the highest confidence value.

In this embodiment of the present application, when the user uses the terminal to shoot horizontally, the direction of the photo that is most suitable for the user can be intelligently identified, and the image taken horizontally by the user can be saved in a direction suitable for the user to refer to, that is, the photo is saved in the forward direction, thereby preventing the user from When the handheld terminal device is taken horizontally, the wrong orientation of the photo is saved, which improves the user's shooting experience.

In some cases, the user himself wants to save a horizontal photo, and the above technical solution will automatically rotate the horizontal photo to save the photo in a positive direction, which goes against the user's original intention.

In response to this situation, the present application provides another method for saving an image, which can make the direction in which the terminal saves the photo consistent with the direction of the image that the user sees in the viewfinder of the screen of the terminal.
