Abstract

The invention discloses a standing long jump detection method based on marks and computer vision. The standing long jump detection method solves the problems that a manual measurement mode is large inworkload and large in result influence, and infrared detection equipment is heavy, very inconvenient to carry and complex to assemble. The method comprises a preprocessing stage, a long jump stage and landing judgment and distance measurement. A contour detection technology is adopted, the influence of texture and noise interference inside a background and a target is avoided, the process of target contour extraction is achieved through digital image processing, and the detection mode is gradually developed into an electronic detection mode from a traditional manual measurement mode. The overall structure is simple, only one camera and equipment with a processing function are needed, the size is small, carrying is convenient, a cost is low and the method is not prone to being affected byperipheral factors.

Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a standing long jump detection method based on markers and computer vision. Background technique [0002] At present, there are many solutions for long jump detection, including: [0003] Manual measurement method, when the athlete takes off and lands, record the long jump distance with a meter ruler through manual measurement method; [0004] A long jump test device and a long jump performance evaluation device, relating to a long jump test device and a long jump performance evaluation device. The long jump testing device includes a distance measuring device and a processing device. The distance measuring device includes an installation mechanism and an infrared range finder, and the infrared range finder is arranged on the installation mechanism. The processing device includes a column, a device main body, an information reading device, a data transmission devic...
