Abstract

The embodiment of the invention discloses an identification method and system for heel key points of standing long jump and a test method. According to the method, a human-containing image and a background image are taken as input, and the problem of identification of the heel key points is decomposed into three steps: human body identification, foot frame identification and heel key point identification through an algorithm; in each step, the output of the previous step is used as the input, the complexity of the problem is gradually reduced, the algorithm utilizes the information that the key points of the heel is a certain point on the human body contour, the feature information of human body segmentation is introduced in the middle, and the features of human body segmentation and key point identification are fused for multiple times in the algorithm; the method assists in the identification of the key points of the heel, directly outputs the key points of the heel after analysis, improves the recognition precision of the heel of the standing long jump, and guarantees the effectiveness and reliability of the distance measurement of a standing long jump result.

Description

technical field

[0001] The invention relates to the technical fields of image segmentation and IT application, in particular to a method, system and test method for identifying key points of the heel of a standing long jump. Background technique

[0002] In the field of human key point recognition and human body contour recognition, including the recognition of human skeleton key points and human body contour recognition, the basic framework of the algorithm is to describe the problem as a regression problem of key points or a classification problem of pixel points. The determination of the parameters of the algorithm model is based on supervised learning. By learning a large number of pictures marked with key points, the optimal or better value of the parameters is found. The key point identification algorithm described above is a general-purpose algorithm. Key point recognition in special fields can be combined with application scenarios to improve the accuracy of key poi...
