Title: KEY POINT DETECTION METHOD AND DEVICE, STORAGE MEDIUM AND ELECTRONIC DEVICE
Abstract:
The embodiments of the present application provide a key point detection method and device, a storage medium, and an electronic device. The key point detection method comprises: acquiring video optical flow data according to a first video frame and a second video frame in a video sequence, wherein the video optical flow data is used to indicate displacement data of at least one pixel between the second video frame and the first video frame, and the second video frame comprises at least one temporally consecutive video frame in the video sequence and located before the first video frame; and acquiring, according to acquired second key point data of a target object in the second video frame and the acquired video optical flow data, first key point data of the target object in the first video frame. The embodiments of the present application can accurately position a key point in consecutive video frames by using timing information of the consecutive video frames.
