Research on Application of Plan Surveying Technology in Shot-Put Sports
Jian Zhang, Wan Juan Song · Applied Mechanics and Materials · 2014
As there may be measuring errors caused by elasticity of measuring tools, uneven fields and man-made interface, thus impacting scientificity and fairness of contests when adopting manual measurement in shot contests, this article puts forward apply monocular vision measuring technique to achievement measure based on domestic and international research status of monocular vision measuring technique and combines characteristics of shot fields to propose an approach to measure throwing range with plane calibration. The experiments proved that this approach is feasible in throwing events.
