Abstract

Embodiments of the invention provide a key point detection method and apparatus, a storage medium and an electronic device. The key point detection method comprises the steps of obtaining video optical flow data according to first video frames and second video frames comprised in a video sequence, wherein the video optical flow data is used for indicating displacement data of pixels between the second video frames and the first video frames, and the second video frames include at least one video frame having a continuous time sequence and located before the first video frames in the video sequence; and according to obtained second key point data of target objects in the second video frames and the video optical flow data, obtaining first key point data of target objects in the first videoframes. By adopting the method and the apparatus, the time sequence information of the continuous video frames can be effectively used for accurately locating key points in the continuous video frames.

Description

technical field

[0001] Embodiments of the present invention relate to machine learning technology, and in particular to a key point detection method, device, storage medium and electronic equipment. Background technique

[0002] Key point detection of objects (such as pedestrians, animals, vehicles, etc.) is an important technology used in applications involving video content analysis and retrieval, and is widely used in robotics, game entertainment, content analysis and recommendation of video websites, etc. At present, the research on object key point detection is divided into image-based key point detection and video-based key point detection.

[0003] For example, in video-based human key point detection, most still rely on image-based human key detection to process continuous video frames, which can easily cause problems such as inaccurate key point positioning, large amount of calculation, and time-consuming calculation.
