The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the related art, a panoramic camera supports a panoramic photographing function of a 360-degree photographing angle, a user uses the panoramic camera to photograph panoramic photos/videos of the 360-degree photographing angle, the panoramic camera can be connected with a panoramic camera App installed on a mobile phone or a tablet personal computer or other terminals, and the user can remotely control the panoramic camera to photograph or preview the panoramic photos/videos in the camera through the panoramic camera App. However, in a panoramic photo obtained by a user using a panoramic camera for self-photographing, a human body image only occupies a part of the whole panoramic photo, and when the human body image is out of the default preview angle of the panoramic photo, the user cannot see the image of the user when previewing the panoramic photo, so that the preview effect of the panoramic photo is affected, and the user experience is reduced.
In order to solve the above problem, an embodiment of the present disclosure provides a method for displaying a panoramic photo, where the method includes: carrying out image recognition on the panoramic photo, and determining a target portrait area in the panoramic photo; acquiring a relative angle of a target portrait area in the panoramic photo; and determining a target preview angle of the panoramic photo according to the relative angle of the target portrait area in the panoramic photo, wherein the image area corresponding to the target preview angle of the panoramic photo comprises the target portrait area. According to the panoramic photo display method provided by the embodiment of the disclosure, the target portrait area in the panoramic photo is determined through the image recognition technology, the target preview angle of the panoramic photo is determined according to the relative angle of the target portrait area in the panoramic photo, and the target portrait area can be located in the image area corresponding to the target preview angle of the panoramic photo, so that a user can see the image of the user when previewing the panoramic photo, the preview effect of the panoramic photo is ensured, and the user experience is improved.
Based on the above analysis, the following specific examples are proposed.
Fig. 1 is a flowchart illustrating a method of displaying a panoramic photograph according to an exemplary embodiment. The execution main body of the method can be a terminal, for example, the terminal can be a panoramic camera, a smart phone supporting a panoramic shooting function, a tablet personal computer or wearable equipment and the like; as shown in fig. 1, the method comprises the following steps 101-103:
in step 101, image recognition is performed on the panoramic photo to determine a target portrait area in the panoramic photo.
For example, when a user needs to preview a panoramic photo, image recognition analysis is performed on the panoramic photo to determine a target portrait area in the panoramic photo; the target portrait area in the panoramic photograph refers to a portrait area that can be displayed on the screen at the time of preview of the panoramic photograph.
For example, when two or more portrait areas are included in the panoramic photo, the implementation manner of determining the target portrait area in the panoramic photo at least includes any one of the following manners:

For example, when the panoramic photo needs to be previewed, the panoramic photo is analyzed, and the human body area containing the front face is preferentially determined as the target human image area.
Mode 2) carrying out image recognition on the panoramic photo to obtain at least one candidate portrait area in the panoramic photo; acquiring the number of people in each candidate portrait area; and determining the candidate portrait area with the largest number of people as the target portrait area in the panoramic photo.
