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。
In the field of deformation monitoring, three-dimensional laser scanning measurement technology has a good application prospect. Aiming at the three-dimensional laser scanner can identify the minimum deformation of the monitored object, that is, the recognition of deformation, which is of guiding significance to the design of the deformation monitoring scheme. A method to detect the deformation of 3D laser scanner is proposed. By constructing the theoretical error model of deformation monitoring, the error model is validated experimentally. The results show that the effect of scanning distance and angle on the recognition of deformation is in good agreement with the experimental results. The correctness of the model is verified, which shows that the method is feasible.
