现有平面标靶均是与激光扫描仪相配套的特制标靶,制作成本较高且标靶不具有通用性。然而野外测量通常需要大量标靶。为此,依据测量需要,选取设计一种材料简单易得、价格低廉、方便携带的自制标靶,通过一定算法,获得自制平面标靶中心三维坐标。通过对Leica Scan Station2型地面激光扫描仪获取的实测数据进行实验分析,结果表明,该算法能够获取自制标靶中心坐标,获取精度优于5 mm,在一定程度上满足野外测量需求。研究结果可为通用标靶选取与中心识别提供参考与借鉴。

Existing plane target is a special target matching laser scanners with higher production costs and the target does not have the versatility. However, field measurements usually require a lot of targets. To meet the measurement needs, design a homemade target with simple and easy material, inexpensive, easy to carry, based on a certain algorithm to obtain three-dimensional coordinates of the target homemade plane center. Through the measured data Leica Scan Station2 type terrestrial laser scanner to obtain the experimental analy-sis, the results show that the algorithm can get homemade target center coordinates, with accuracy better than 5mm to meet the needs of field measurements to some extent. The results can provide reference for common target selection and center identification.
