Abstract

The invention provides an optical measurement method for long-distance running, the method comprising: athletes wear reflective signs; a modulated light source and an image capture device are installed at the physical end point of the track; Shooting images continuously towards the physical end point under the light of the second intensity, further comprising the steps of: acquiring a bright frame image taken by the image capturing device under the light of the first intensity; Frame image; differentially process the bright frame image and the dark frame image to obtain a differential image; detect whether a logo appears in the differential image, if so, identify the identity of the athlete through the logo, and mark the frame where the logo appears. The invention also provides a corresponding optical measurement system. Compared with other photographic identification methods, the present invention has beneficial effects such as strong resistance to ambient light interference, low identification cost, high accuracy, and easy operation.

Description

Technical field [0001] The present invention relates to the field of sports testing, in particular to an optical measurement method and system for long-distance running. Background [0002] At present, with the improvement of people's living standards and the emphasis on physical health, physical exercise has become a popular activity of the people. Among them, running is a fitness method that not only trains people's physical fitness but also increases people's patience. This is especially true for long-distance running. Long-distance running can increase the body's respiratory system and cardiovascular system function, and promote people to maintain long, rhythmic breathing, which helps to soothe the mood and is conducive to physical and mental health. At the same time, because long-distance running has the characteristics of not introducing complex sports equipment and the sports field is more accessible, it is often considered by the public to be a generally implementable exe...
