Abstract

The invention provides a key point detection model construction method and device, electronic equipment and a storage medium, and relates to the technical field of image processing. According to the technical scheme provided by the invention, the key points in each frame of image are labeled by using the single-frame detection model to obtain the pseudo-labeled data, and the key point prediction result of the time sequence model is supervised by using the pseudo-labeled data, so that the key point detection model applied to detection of the key points of the to-be-detected object in the video image is constructed. According to the technical scheme provided by the invention, the construction efficiency of the key point detection model can be improved, and the key point detection cost of the video image is reduced.

Description

Technical field [0001] The present disclosure relates to the field of image processing, and more particularly to a construction method of a critical point detection model, a key point detection method, apparatus, an electronic device, and a storage medium of a video image. Background technique [0002] With the development of image processing technology, there is a technique for detecting key points of objects such as face, vehicles. For example, a key point detection in a video image is a very important technique, and the accuracy of face key detection is directly related to subsequent applications, such as expression analysis, three-dimensional animation, face three-dimensional reconstruction. [0003] In the related art, when detecting the key points of the object to be detected in the video image, it is necessary to rely on a large amount of manual data set, and by obtaining a critical point detection model, such a key point detection model is obtained. The construction metho...
