建筑物重建中的三维激光扫描精度分析

The Accuracy Analysis of 3D Laser Scanning in Building Reconstruction

针对三维激光扫描技术在建筑物重建中数据采集、处理方面存在的误差,从三维激光扫描仪测站定向误差、仪器扫描误差、数据拼接误差进行分析,并构建了点位误差模型,为三维激光扫描技术在建筑物的重建中测量成果的精度评定及测量方案的优化设计提供了理论基础.最后以脉冲式三维激光扫描仪为例对建筑物重建进行精度分析.

According to the error of data collection and data processing,when we use 3D laser scanning technologyin the process of building reconstruction,the paper mainly aims at analyzing station directional error,instrumentscanning errors and data splicing errors of 3D laser scanner,and forms point error model. It provides theoreticalfoundation for accuracy evaluation in the measuring outcomes and optimized design of the measurement program.Finally,we analyze the accuracy of the reconstruction of building using pulsed laser scanner.
