不同扫描方式对平面标靶拟合精度的影响

Effects of Different Scanning Modes on Target Plane Fitting Precision

由于地面三维激光扫描仪扫描精度对扫描距离、扫描分辨率及扫描方向具有很强的依赖性,因此研究其与扫描距离、扫描分辨率及扫描方向的关系对实验分析及工程应用具有很重要的意义。本文利用Faro Focus 3D激光扫描仪从不同距离、扫描分辨率、扫描方向对不同形状的平面标靶进行实验,研究不同的扫描方式对平面标靶拟合精度的影响,并进一步判断扫描仪是否存在较大的轴系误差,为后期的自检校提供依据。

Because the scanning accuracy of terrestrial 3D laser scanner is strongly dependent on the scan range , resolution and scan-ning direction, the study of its relationship with the scanning range , resolution and scanning direction is very important for the experi-mental analysis and engineering application .This paper, using the Faro Focus 3D laser scanner experiments from different distance , scanning resolution , scanning direction plane target of different shape , to study the effect of different scanning modes on the target plane fitting precision , and further judge whether there is large error scanner system , provides the basis for the self -calibration later .
