【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。更多还原

【Abstract】 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.更多还原
