一、前言田径跑道的丈量方法是向着越来越精确、操作方法越来越简化的方向发展的。目前常用的丈量方法,有以下两个共同点: 1、丈量点在跑道的分道线上; 2、依据一个丈量点,靠人的视觉画分道线和分道线切线的垂直线。而分道线的可变性较跑道内、外突沿要大得多。同时,分道线若消失,丈量点亦消失。因此,每画一次分道线,则需重新丈量。靠人的视觉画线,难以保证所画线段方向的
I. Introduction Track and Field runway measurement methods are toward more and more accurate, more and more simplified method of operation in the direction of development. Commonly used measurement methods, the following two things in common: 1, measuring points in the runway of the lane; 2, based on a measurement point, depending on the person’s visual line and lane dividing line of the vertical line tangent. The variability of the lane separation is much larger than that of the runway. At the same time, the dividing line disappears and the measuring point disappears. Therefore, each draw lane line, you need to re-measure. Draw lines by people’s vision, it is difficult to guarantee the direction of the line drawn by the
