数字近景摄影测量辅助三维激光影像扫描的建筑物表面数据采集系统

Collecting System of Building Surface Data with Three-D Laser Scanning Survey Aided with Digital Photogrammetry

根据三维激光影像扫描技术和数字近景摄影测量的特点,以完整地采集复杂建筑物表面的三维坐标数据为目标,提出数字近景摄影测量与三维激光影像扫描测量相结合进行建筑物表面的三维点的采集方案,并根据设计方案和数学模型编制相关程序,初步实现相应的数据采集步骤。

The characteristic of Three-D laser scanning technique and digital photogrammetry are analysed in the paper. Aiming at collecting the Three-D D coordinates of complicated building surface, the collection scheme of combination Three-D laser scanning survey with digital photogrammetry is proposed in the paper. According to the design and mathematical model, the programme of main functions has been completed and the work steps are primarily set up.
