等高点偏心测量法

On high eccentricity measuring method

通过测量建筑物墙面上两等高点的竖角及其方向,推算两等高点连线的坐标方位角,并在两点连线上设立偏心点并测量其坐标,根据等高点方位角和偏心点坐标可推算两等高点的坐标,指出该方法可部分解决待测房角点因不能立棱镜或视线受阻而无法测量的问题,且测量精度可以达到大比例测图精度要求。

By measuring the vertical angle and direction of the two height points of buildings,the paper deduces the coordinate azimuth of the two lines of the height points,allocates the eccentricity point of the two lines,measures their coordinates,deduces the coordinate of the two height points according to the high azimuth and eccentricity coordinate,and points out the method can partially solve the failure in the measurement caused by the prism or eyesight of the angular points of houses for the measurement and the measurement accuracy can achieve the accuracy of large proportional mapping.
