In some possible implementations, the photographing method may be implemented by a processor calling computer-readable instructions stored in a memory. As shown in fig. 1, the method includes steps S11 through S13.

In step S11, a posture shooting request for requesting shooting based on the posture of the photographic subject is received.

In one possible implementation manner, when the gesture shooting button in the shooting interface is in the off state, if it is detected that the gesture shooting button is clicked, it is determined that the gesture shooting request is received, and the gesture shooting button is switched to the on state.

In one possible implementation, the gesture capture request is an image capture request. In this implementation, the gesture capture request may be for capturing an image.

In one possible implementation, the gesture capture request includes a gesture capture mode start request; after receiving the gesture photographing request, the method further includes: and starting the posture shooting mode based on the posture shooting mode starting request.

In one example, the gesture capture request may include only the gesture capture mode turn-on request, and not the gesture selection request. In this example, all of the alternative gestures may be determined to be preset gestures, respectively, without requiring the user to select from among the alternative gestures.

Fig. 2 illustrates a schematic diagram of a gesture photographing button in a photographing method according to an embodiment of the present disclosure. In fig. 2, the posture shooting button 21 is in an off state, that is, the posture shooting mode is in an off state.

In one example, the gesture capture mode is in an off state by default. That is, when the user starts the camera application, the gesture shooting button and the gesture shooting mode are in the off state by default. The gesture shooting mode is defaulted to the closed state, and the memory occupation can be reduced.

In one example, as shown in fig. 2, the gesture shooting button is one of the function items of the shooting interface, and the priority presented may be the same as the delay shooting button.

In one possible implementation, the gesture capture request further includes a gesture selection request; after receiving the gesture photographing request, the method further includes: based on the gesture selection request, one or more of the alternative gestures are determined to be a preset gesture. In this implementation, the preset gesture may be selected by the user from the alternative gestures.

Fig. 3 shows a schematic diagram of an alternative gesture selection interface in a shooting method according to an embodiment of the present disclosure. In fig. 3, the posture shooting button 21 is in an on state, that is, the posture shooting mode is in an on state. In the example shown in FIG. 3, the alternative poses include a "horse dance" pose, a "space step" pose, and a running pose.

It should be noted that although alternative attitudes have been described above with "horse dance" attitude, "space step" attitude, and running attitude as examples, those skilled in the art will appreciate that the present disclosure should not be limited thereto. Those skilled in the art can flexibly set alternative gestures according to the requirements of the actual application scene and/or personal preference.

In step S12, based on the orientation photographing request, a preview image is captured, and orientation information of the photographic subject in the preview image is acquired.

In one possible implementation, the method further includes: and determining the object of the specified type in the preview image as the shooting object. For example, the specified type is a human body or at least a part of a human body.

In one possible implementation manner, the preview image is continuously acquired in response to the gesture shooting request, and the gesture information of the shooting object in the preview image is acquired in real time.

In step S13, if the posture information of the photographic subject matches the information of the preset posture, a photographing operation is triggered.

In the embodiment of the present disclosure, the number of the preset gestures may be one or more.

In a possible implementation manner, if the number of the preset gestures is multiple, when the gesture information of the shooting object matches with the information of any one preset gesture, the shooting operation is triggered.

In a possible implementation manner, the attitude information of the photographic subject may be matched with the information of the preset attitude in real time to determine whether the attitude information of the photographic subject is matched with the information of the preset attitude.

In a possible implementation manner, if the posture information of the photographic object matches with the information of the preset posture, triggering a photographing operation includes: and if the preview image has a plurality of shot objects and the posture information of at least one shot object in the plurality of shot objects is matched with the preset posture information, triggering the shooting operation.

In one possible implementation, triggering a shooting operation includes: the countdown is started and the shooting is started after the countdown is finished. In one example, the countdown may be a 3 second countdown of 3, 2, 1. In this example, in response to the posture information of the photographic subject matching the information of the preset posture, 3, 2, 1 of 3 second countdown is started, and the photographing is started after the countdown is ended.

In the embodiment of the present disclosure, the key point of the photographic subject may be a feature point capable of representing the posture of the photographic subject. For example, the number of key points of the photographic object is 18 or 20, which is not limited by the embodiment of the present disclosure.

In one possible implementation, the key points of the photographic subject are determined at least from the joint points of the photographic subject. For example, the key points of the photographic subject include a plurality of or all of a nose key point, a neck key point, a left shoulder key point, a right shoulder key point, a left upper arm key point, a right upper arm key point, a left elbow key point, a right elbow key point, a left wrist key point, a right wrist key point, a thoracic vertebra key point, a lumbar vertebra key point, a sacral vertebra key point, a caudal vertebra key point, a left hip key point, a right hip key point, a left knee key point, a right knee key point, a left ankle key point, and a right ankle key point.

In one possible implementation manner, the attitude information of the photographic subject comprises relative position information of a first key point of the photographic subject relative to a second key point of the photographic subject, wherein the first key point represents any key point except the second key point in the key points of the photographic subject; the information of the preset posture comprises relative position information of a third key point of the preset posture relative to a fourth key point of the preset posture, wherein the third key point represents any one key point except the fourth key point in the key points of the preset posture; after acquiring the pose information of the photographic subject in the preview image, the method further includes: determining a position deviation value of the first key point according to the relative position information of the first key point relative to the second key point and the relative position information of the third key point relative to the fourth key point; and judging whether the attitude information of the shot object is matched with the preset attitude information or not according to the position deviation value of the first key point.

In one example, the relative position information may be relative coordinates. For example, for a photographic subject, the relative coordinates of a first key point of the photographic subject with respect to a second key point may be determined with the second key point of the photographic subject as the origin; for the preset posture, the relative coordinates of the third key point of the preset posture relative to the fourth key point can be determined by taking the fourth key point of the preset posture as an origin.

In another example, the relative position information may be a vector. For example, the relative position information of the first keypoint with respect to the second keypoint may be a vector of the first keypoint pointing to the second keypoint; alternatively, the relative position information of the first keypoint with respect to the second keypoint may be a vector of the second keypoint pointing to the first keypoint.

In one example, determining whether the posture information of the photographic subject matches the information of the preset posture according to the position deviation value of the first key point includes: if the average value of the position deviation values of the first key points of the shot object is smaller than a first threshold value, judging that the attitude information of the shot object is matched with the information of the preset attitude; and if the average value of the position deviation values of the first key points of the shot object is greater than or equal to the first threshold, judging that the posture information of the shot object is not matched with the preset posture information.

In another example, determining whether the posture information of the photographic subject matches the information of the preset posture according to the position deviation value of the first key point includes: if the sum of the position deviation values of all the first key points of the shot object is smaller than a second threshold value, judging that the attitude information of the shot object is matched with the information of the preset attitude; and if the sum of the position deviation values of the first key points of the shot object is greater than or equal to the second threshold, judging that the posture information of the shot object is not matched with the information of the preset posture.

In one example, the second key point is a lumbar key point of the photographic subject, the fourth key point is a lumbar key point in the preset posture, the first key point of the photographic subject includes a nose key point, a neck key point, a left shoulder key point, a right shoulder key point, a left upper arm key point, a right upper arm key point, a left elbow key point, a right elbow key point, a left wrist key point, a right wrist key point, a thoracic vertebra key point, a sacral vertebra key point, a caudal vertebra key point, a left hip key point, a right hip key point, a left knee key point, a right knee key point, a left ankle key point and a right ankle key point of the photographic subject, and the third key point of the preset posture includes a nose key point, a neck key point, a left shoulder key point, a right shoulder key point, a left upper arm key point, a right upper arm key point, a left elbow key point, a right elbow key point, a left wrist key point, a right wrist key point, a nose key point, a neck key point, Thoracic vertebra, sacral vertebra, coccygeal vertebra, left hip, right hip, left knee, right knee, left ankle and right ankle key points.

For example, if the relative position information is a relative coordinate, a distance between a relative coordinate of a nose key point of the photographic subject with respect to a lumbar key point and a relative coordinate of a nose key point of a preset posture with respect to a lumbar key point may be determined as a position deviation value of the nose key point of the photographic subject. By analogy, the position deviation value of each first key point of the photographic subject can be determined.

For another example, if the relative position information is a vector, an included angle between a vector of the nose key point of the photographic subject relative to the lumbar key point and a vector of the nose key point of the preset posture relative to the lumbar key point may be determined as a position deviation value of the nose key point of the photographic subject. By analogy, the position deviation value of each first key point of the photographic subject can be determined.

In another possible implementation, the pose information of the photographic subject includes coordinates of a plurality of key points of the photographic subject; the preset posture information comprises coordinates of a plurality of key points of the preset posture; after acquiring the pose information of the photographic subject in the preview image, the method further includes: determining the similarity between the plurality of key points of the shot object and the plurality of key points of the preset posture according to the coordinates of the plurality of key points of the shot object and the coordinates of the plurality of key points of the preset posture; and judging whether the posture information of the shooting object is matched with the preset posture information or not according to the similarity.

In this implementation, similarity between a plurality of key points of the photographic subject and a plurality of key points of the preset pose may be determined using a feature matching model in the related art.

In one example, if the similarity between the plurality of key points of the photographic object and the plurality of key points of the preset posture is greater than a third threshold, determining that the posture information of the photographic object matches the information of the preset posture; and if the similarity between the plurality of key points of the shooting object and the plurality of key points of the preset posture is smaller than or equal to a third threshold value, judging that the posture information of the shooting object is not matched with the information of the preset posture.

In one possible implementation manner, if the gesture shooting request is a video shooting request, after triggering the shooting operation, the method further includes: acquiring attitude information of a shot object in a shot video frame; and if the posture information of the shooting object is matched with the preset posture information, ending the shooting.

In one example, the preset posture corresponding to ending the photographing may be different from the preset posture corresponding to starting the photographing.

In another example, the preset posture corresponding to the end of the photographing may be the same as the preset posture corresponding to the start of the photographing.
