| 摘 要： | 3维激光扫描仪扫描得到的是目标点的相对坐标,无法直接满足需要大地坐标的工程应用的要求,且不同扫描站间点云数据的拼接非常麻烦。对这些问题,让3维激光扫描仪如全站仪一样能够直接获得大地坐标是一种理想的解决办法。分析了3维激光扫描仪的工作原理,介绍了扫描仪的极坐标系和直角坐标系并推导了其转换关系;在扫描仪中引入旋转平台和平台坐标系,推导了平台坐标系与扫描坐标系及大地坐标系之间的转换模型。在此基础上将扫描坐标转化为大地坐标,实现3维激光扫描仪的全站化。

| Abstract: | The 3D laser scanner can get the points cloud of target based on the relative coordinate system,which cannot satisfy the applications straightway when the geodetic coordinates are needed.It is a complicated job to layout the points cloud from different stations.A perfect solution is to improve the 3D laser scanner that could get the points cloud which based on geodetic coordinate system directly.In this solution,a rotary platform and the platform coordinate system are imported into the scanner system and th... |
