Fig. 2 is a flowchart illustrating a camera turning-on method for use in a terminal according to an exemplary embodiment. As shown in fig. 2, the method includes the following steps.
In step 201, when a camera opening instruction is detected, current attitude data of the terminal is acquired.
It should be noted that the camera opening instruction is used to instruct to open the camera, and the camera opening instruction may be triggered by a user, where the user may trigger through a specified operation, and the specified operation may be a single-click operation, a double-click operation, a voice operation, and the like, which is not specifically limited in this embodiment of the present disclosure. For example, when a user opens a camera application in a terminal through a single-click operation, the single-click operation may trigger the camera opening instruction to open a camera.
In addition, the attitude data is used to indicate an attitude in which the terminal is currently located, and the attitude may include at least one of a height, a horizontal and vertical screen state, a pitch state, and a tilt angle, which is not specifically limited in this disclosure. The height is the distance between the terminal and the nearest barrier in the gravity direction; the horizontal and vertical screen states comprise a vertical screen, an inverted vertical screen, a left horizontal screen and a right horizontal screen; the pitching state comprises a pitching state and a pitching state, wherein the pitching state represents that the screen of the terminal faces downwards, and the pitching state represents that the screen of the terminal faces upwards; the inclination angle comprises a horizontal inclination angle and a vertical inclination angle, the horizontal inclination angle is an included angle between the terminal and the horizontal plane, and the vertical inclination angle is an included angle between the terminal and the vertical plane.
When acquiring the current attitude data of the terminal, the current attitude data of the terminal may be acquired through a gravity sensor, a direction sensor, a three-axis gyroscope, a distance sensor, and the like configured in the terminal, which is not specifically limited in this embodiment of the disclosure. In addition, the operation of acquiring the current attitude data of the terminal may refer to the related art, which is not described in detail in the embodiments of the present disclosure.
In step 202, a camera to be turned on is determined based on the current attitude data of the terminal.
Because the front camera and the rear camera are generally different in purpose, if the front camera is generally used for self-shooting, and the rear camera is generally used for shooting, the posture of the terminal when the user uses the front camera and the rear camera is different, if the user uses the front camera, the height of the terminal is generally higher than the height of the terminal when the user uses the rear camera, and the posture of the terminal can indicate which camera the terminal is started to a certain extent, so that the camera to be started can be determined based on the current posture data of the terminal. When the camera to be turned on is determined based on the current attitude data of the terminal, the shooting mode corresponding to the current attitude data of the terminal can be determined by specifying the attitude model based on the current attitude data of the terminal, and the camera to be turned on is determined based on the shooting mode corresponding to the current attitude data of the terminal.
It should be noted that the designated pose model is used to determine a shooting mode corresponding to the pose data, and the designated pose model may distinguish multiple shooting modes, where the multiple shooting modes may include a self-timer mode, a shooting mode, and the like, and this is not specifically limited in this embodiment of the disclosure.
In addition, before the shooting mode corresponding to the current attitude data of the terminal is determined through the specified attitude model based on the current attitude data of the terminal, the specified attitude model can be established in advance, and when the specified attitude model is established, a plurality of training attitude data sets can be obtained first, and then the attitude model to be trained is trained by using the plurality of training attitude data sets to obtain the specified attitude model.
It should be noted that each of the plurality of training posture data sets includes at least one training posture data, and each training posture data set corresponds to one shooting mode, that is, each training posture data is a posture data with a shooting mode identifier.
In addition, when a plurality of training posture data sets are acquired, the posture data of the terminal and the shooting mode corresponding to the camera used at this time may be acquired each time a shooting operation is performed, the acquired shooting mode is determined as the shooting mode corresponding to the posture data acquired at this time, and then the posture data with the shooting mode identifier is determined as the training posture data. The front camera may correspond to a self-photographing mode, and the rear camera may correspond to a shooting mode, which is not specifically limited in the embodiments of the present disclosure.
Furthermore, when the plurality of training pose data sets are used to train the pose model to be trained, the embodiment of the present disclosure may train the pose model to be trained in a supervised learning manner, where the supervised learning means a process of continuously adjusting parameters in the pose model by specifying an adjustment algorithm to make the pose model achieve the required performance given the input and output of the pose model. In the embodiment of the present disclosure, the input is training posture data, and the output is a shooting mode corresponding to the training posture data.
It should be noted that the designated adjustment algorithm may be preset, for example, the designated adjustment algorithm may be a random gradient descent algorithm, and this is not specifically limited in this disclosure.
Based on the shooting mode corresponding to the current attitude data of the terminal, the operation of determining the camera to be turned on may be: judging whether a shooting mode corresponding to the attitude data of the terminal is a self-shooting mode or not; and when the shooting mode corresponding to the current attitude data of the terminal is not the self-shooting mode, determining that the camera to be started is a rear camera.
When the shooting mode corresponding to the current attitude data of the terminal is not the self-shooting mode, the user is not likely to want to use the front camera to carry out self-shooting, so that the camera to be turned on can be determined to be the rear camera.
Further, after judging whether the shooting mode corresponding to the attitude data of the terminal is the self-shooting mode, when the shooting mode corresponding to the attitude data of the terminal is the self-shooting mode, the camera to be turned on can be determined through the following three ways.
The first mode is as follows: and when the shooting mode corresponding to the current attitude data of the terminal is a self-shooting mode, determining that the camera to be started is a front-facing camera.
When the shooting mode corresponding to the current attitude data of the terminal is the self-shooting mode, it is indicated that the user is more likely to want to use the front camera to carry out self-shooting, so that the camera to be turned on can be determined to be the front camera. At the moment, after the shooting mode corresponding to the current attitude data of the terminal is determined, the camera to be started can be determined only according to the shooting mode corresponding to the current attitude data of the terminal, and the determination efficiency is high.
The second mode is as follows: when the shooting mode corresponding to the current attitude data of the terminal is a self-shooting mode, determining the shooting probability of the front camera; when the shooting probability of the front camera is greater than or equal to the designated probability, determining that the camera to be started is the front camera; and when the shooting probability of the front camera is smaller than the designated probability, determining that the camera to be started is the rear camera.
It should be noted that the designated probability may be preset, for example, the designated probability may be 0.7, 0.8, and the like, which is not specifically limited in this disclosure.
When the shooting probability of the front-facing camera is determined, the shooting probability of the front-facing camera may be obtained by dividing the number of times of shooting by using the front-facing camera by the total number of times of shooting by the terminal. In addition, when the shooting probability of the front camera is greater than or equal to the designated probability, the user often uses the front camera to shoot, and when the shooting probability of the front camera is less than the designated probability, the user infrequently uses the front camera to shoot.
When the shooting mode corresponding to the current attitude data of the terminal is a self-shooting mode, if the shooting probability of the front camera is greater than or equal to the specified probability, it is indicated that the user probably wants to use the front camera to carry out self-shooting, and the camera to be started can be determined to be the front camera. And if the shooting probability of the front camera is smaller than the specified probability, the fact that the user is less likely to want to use the front camera to take a self-timer is indicated, and the camera to be started can be determined to be the rear camera. At this time, after the terminal determines that the shooting mode corresponding to the current attitude data of the terminal is the self-shooting mode, the camera to be started can be further determined according to the shooting probability of the front camera, and the determination accuracy is high.
The third mode is as follows: when a shooting mode corresponding to the current attitude data of the terminal is a self-shooting mode, acquiring an image through a front camera; and determining the camera to be started based on the acquired image.
The operation of acquiring an image through a front camera may refer to the related art, which is not described in detail in the embodiments of the present disclosure.
Based on the acquired image, the operation of determining the camera to be turned on may be: judging whether the collected image contains a face image or not; and when the acquired image does not contain the face image, determining that the camera to be started is a rear camera.
Because the user usually shoots the face of the user when using the front camera to shoot the self, when the collected image does not contain the face image, the user is less likely to want to use the front camera to shoot the self, and the camera to be started can be determined to be the rear camera.
The operation of determining whether the acquired image includes a face image may refer to related technologies, which are not described in detail in the embodiments of the present disclosure.
Further, after judging whether the acquired image contains a face image or not, when the acquired image contains the face image, determining that the camera to be started is a front-facing camera; or when the acquired image contains a face image, identifying the face expression of the face image, when the identified face expression is a specified expression, determining that the camera to be started is a front camera, and when the identified face expression is not the specified expression, determining that the camera to be started is a rear camera.
On one hand, because the user usually shoots the face of the user when using the front camera to shoot the self, when the collected image contains the face image, the user is more likely to want to use the front camera to shoot the self, and the camera to be started can be determined to be the front camera. At the moment, after the terminal collects the image through the front camera, the camera to be started can be determined only according to the existence of the face image in the image, and the determination efficiency is high.
On the other hand, when the user uses the front camera to shoot the face of the user, the facial expression of the user is usually fixed, for example, the facial expression of the user is usually smiling, so when the collected image contains a facial image, if the recognized facial expression is a specified expression, it indicates that the user is likely to want to use the front camera to shoot by self, the camera to be turned on can be determined to be the front camera, and if the recognized facial expression is not the specified expression, it indicates that the user is less likely to want to use the front camera to shoot by self, and it can be determined that the camera to be turned on is the rear camera. At this time, after the terminal determines that the acquired image contains the face image, the camera to be started can be further determined according to the face expression of the face image, and the determination accuracy is high.
It should be noted that the designated expression may be preset, for example, the designated expression may be smiling, and this is not specifically limited in this disclosure. In addition, in actual use, the specified expression may be set by the terminal, and when the terminal sets the specified expression, the terminal may perform facial expression recognition on all facial images obtained by the user using the front-facing camera, and determine the facial expression with the largest occurrence frequency in the recognized facial expressions as the specified expression.
When the acquired image includes a face image, the operation of recognizing the facial expression of the face image may refer to related technologies, which are not described in detail in the embodiments of the present disclosure.
It should be noted that, in the embodiment of the present disclosure, the terminal may determine the camera to be turned on according to the shooting mode corresponding to the current posture data of the terminal directly, and may assist in determining the camera to be turned on by using the image, the face image, or the facial expression acquired by the front-facing camera on the basis of determining the shooting mode corresponding to the current posture data of the terminal. And when the terminal directly determines the camera to be started according to the shooting mode corresponding to the current attitude data of the terminal, the determination efficiency is higher. When the terminal determines the camera to be started by using the images, the face images or the facial expressions acquired by the front-facing camera on the basis of determining the shooting mode corresponding to the current attitude data of the terminal, the determination accuracy is high.
In step 203, the camera to be turned on is turned on.
It should be noted that, reference may be made to related technologies for the operation of turning on the camera to be turned on, which is not described in detail in the embodiments of the present disclosure.
In the embodiment of the disclosure, when a camera opening instruction is detected, current posture data of a terminal is obtained, a camera to be opened is determined based on the current posture data of the terminal, and then the camera to be opened is opened.
