基于控制点约束的地面三维激光扫描仪自检方法研究

摘要

以FARO公司的Focus3D X330扫描仪作为检测对象,提出了一种以控制点为约束的地面三维激光扫描仪自检方法.该方法利用仪器自带的对称基座和半球形标靶,采用高精度的全站仪现场测设的控制点为参考基准,对扫描仪的标靶拟合距离、测距精度、水平角和竖直角的测量精度进行了检测评估.该方法简而易行,对未来扫描仪检测行业标准的制定具有一定的指导作用.%Taking Focus3D X330 scanner of FRAO as the checked object,a self-check method of terrestrial 3D laser scanner based on the constraint of control points is proposed.By using of accessory symmetric bases,hemispheric target,and reference points measured by precise total station in the field,the longest distance of fitting coordinates of targets and the accuracy of the scanner for measuring distance,horizontal angle,and vertical angle are checked.The self-check method,which is simple and easy,will provide a guidance for the formulation of the professional standard for checking terrestrial 3D laser scanner.
