摘要
在变形监测领域,三维激光扫描测量技术有着良好的应用前景。针对三维激光扫描仪能够识别被监测物体的最小变形量,即变形识别度,对变形监测方案设计的指导意义,该文提出了一种检测三维激光扫描仪变形监测识别度的方法。通过构建变形监测的理论误差模型,用实验对误差模型进行验证。结果显示,扫描仪扫描距离、角度对变形识别度的影响与实验结果较一致,验证了模型的正确性,说明该测试方法具有可行性。
3D laser scanning technology has a good prospect in the field of deformation monitoring, and the deformation recognition known as the minimum distortion of object identified by laser scanner is helpful for deformation monitoring design. In view of this, a detection method of deformation recognition for 3D laser scanner was proposed in this paper. The error model of deformation monitoring was built and validated through experiments. The results showed that the influence of the distance and angle of scanners on the deformation recognition had the same effects with the experimental results, which verified the cor- rectness of the error model and the feasibility of the proposed method.
