Physical constitution detection method and system

Abstract

The invention discloses a physical constitution detection method, which comprises the following steps: 1, continuously shooting testee images at a fixed frame rate by virtue of a camera, and extracting human body postures in the images; 2, analyzing the human body postures extracted from each frame of image according to a time sequence, finding a frame of image in which the human body posture is a detected posture, and marking the frame as an initial frame; 3, continuing performing backward searching to the frame of image at an interval of a preset frame number with the initial frame according to the time sequence by taking the initial frame as the first frame, and marking the frame as an ending frame; 4, counting all the frames from the initial frame to the ending frame, calculating duration from the initial frame to the ending frame in combination with the total frame number and the fixed frame rate, simultaneously obtaining the motion displacement of a testee according to human body posture and position changes from the initial frame to the ending frame, and calculating the physical constitution data of the testee according to the motion displacement. The invention further discloses a corresponding physical constitution detection system. According to the method and the system, vertical jumping items during physical constitution detection can be automatically measured, and the measurement accuracy is high.

Description

technical field [0001] The invention relates to the field of motion detection, in particular to a physical fitness detection method and system. Background technique [0002] At present, with the development of society and economy, the improvement of people's awareness of health, and the changes in the international situation, the country's enhancement of the overall national physique has been raised to a strategic level. In this context, there is an urgent need for more efficient and accurate monitoring of the national physique. [0003] In the "National Physique Measurement Standard Manual and Standards (Adult Part)" issued by the Group Department of the State Sports General Administration in 2003, the national physique test is divided into three categories with a total of 11 test indicators. The indicator of the jump item. [0004] The traditional vertical jump measurement method is as follows: the traditional vertical jump measurement method is that the tester stands on...

AI Technical Summary

Problems solved by technology

[0006] The problem to be solved by the present invention is that when the vertical jump event measurement of the physical fitness test is performed manually, the effective landing time of the tester cannot be accurately identified due to human factors, thereby causing errors in the vertical jump height measurement
