AI Technical Summary

Technical Problem

Existing standing long jump measurement methods suffer from poor measurement accuracy, inability to identify some violations, high equipment installation requirements, and poor environmental adaptability.

Method used

By receiving images of the standing long jump mat, calibrating and obtaining the perspective transformation matrix between the original plane and the new visual plane coordinate system, recognizing the test subject's facial information, sending a take-off preparation prompt, converting the test subject's skeletal data image in real time, judging whether the test subject stepped on/crossed the take-off line, the take-off situation and the landing situation, identifying violations, and calculating the long jump distance.

Benefits of technology

It enables accurate identification of violations, improves the accuracy of standing long jump measurement, simplifies equipment installation, and enhances environmental adaptability.

Abstract

The application discloses a standing long jump measuring method and device, and the method comprises the following steps: calibrating a received standing long jump mat image and obtaining a perspective conversion matrix of an original plane coordinate system and a new view plane coordinate system; sending a take-off preparation prompt information after identifying that the face information of a tester is consistent with the pre-stored information; converting the original plane image including the real-time acquired tester bone data into a new view plane image through the perspective conversion matrix; receiving a first image of the tester in a standing long jump mat take-off area in the new view plane image, determining that the tester does not step / cross the take-off line, detecting the take-off condition of the tester, and detecting the landing image of the tester after determining that the tester takes off; determining whether the tester commits a rule violation through the landing image; if no rule violation is committed, obtaining the long jump distance of the tester based on the landing image; and if a rule violation is committed, sending a rule violation prompt signal. The application can accurately identify the rule violation actions of the tester in the standing long jump process, and improve the measuring accuracy.
