摘要
田赛中的投掷项目需要精确测定投掷距离,可采用全站仪和计算机联机作业,对于TC1700全站仪,投掷距离的测定误差为±3.42mm,所报运动员成绩的可靠度为86.36%,为确保成绩的真实性,应选用测距中误差不大于2mm+2ppm·D且测角中误差不大于5″的全站仪。
The thrown distance in throw event of track meet can be online accurately determined with a total station and a computer.When a TC1700 total station is used,the accuracy of±3 42mm and reliability of 86 36% can be reached.The authors suggest that a total station ,which standard accuracy of distance and angle measurement are better than 2mm+2ppm and 5″ respectively,must be selected for this purpose.
