Abstract

The present application relates to a method, device, electronic device and storage medium for associating detection frames of multiple parts of a human body, wherein the method includes: acquiring a video stream, which includes multiple frames of video images; performing target detection processing on the video images to obtain video images The face detection frame, the head and shoulders detection frame and the human body detection frame; according to the preset external expansion ratio, the face detection frame and the head and shoulders detection frame in the video image, determine the distance between the face detection frame and the head and shoulders detection frame The first association relationship; according to the preset relative ratio, the head and shoulders detection frame and the human body detection frame in the video image, determine the second association relationship between the head and shoulders detection frame and the human body detection frame; according to the first association relationship and the second association relationship to obtain the face detection frame, head and shoulders detection frame, and human body detection frame corresponding to the same person in the video image. Through this application, the problem in the related art that the detection frames corresponding to multiple parts of the human body cannot be accurately correlated is solved.

Description

technical field [0001] The present application relates to the technical field of computer vision, in particular to a method, device, electronic device and storage medium for associating detection frames of multiple parts of a human body. Background technique [0002] Tracking technology has always been one of the hot spots in the field of computer vision research. The core tasks of tracking technology include the prediction of target trajectory and the matching of multiple target historical detection positions. However, the current technologies on target frame matching are almost all about the matching of the same detection position belonging to the same person in two consecutive frames of video images, but rarely involve the association matching of multiple detection positions corresponding to the same person. [0003] In related technologies, by calculating the intersection ratio between the face detection frame and the human body detection frame, the face detection frame...
