The present disclosure relates to a method, a device, an electronic device and a storage medium for acquiring a position of a human face, and relates to the field of computer technology. The method includes: acquiring the ratio of the face area where the human face is located outside the first screen to the human face; when the ratio satisfies the target condition, acquiring the first position of the target part in the second screen and the first position of the target part in the second screen. The first target area including the target part; acquire the position change information of the image feature points in the first target area and the second target area, the second target area is the area including the target part corresponding to the first target area in the second screen ; Based on the first position and the position change information, acquire a second position of the target part in the first screen image. In the present disclosure, when the screen picture only includes part of the human face, the accurate position of the human face can still be obtained, the accuracy is good, there is no recognition situation, and the recognition effect is good.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, electronic device and storage medium for acquiring the position of a human face. Background technique [0002] With the development of computer technology, face recognition technology is more and more widely used. For example, face recognition technology can be combined with augmented reality (Augmented Reality, AR) technology to perform face recognition on the screen, Add other virtual objects. [0003] In the related art, the method for obtaining the position of the face part is usually to collect a screen image, and directly perform face recognition on the collected screen image to obtain the position of the face part. [0004] In the above method, sometimes only part of the human face is located in the screen image. In this case, face recognition is performed directly on the screen image, and the position of the obtained human face may be ina...
