摘要
研究了基于近景数字摄影原理的现场三维精密视觉测量方法,对其核心技术:数字成像器件模型及标定、高精度亚像素图像处理算法以及光学编码与精密测头技术进行了深入的讨论,给出了实现思路,为工业现场近景数字摄影精密测量系统的设计提供了理论依据。
This paper studies an on-field 3D precise visual measurement technique based on digital close range photogrammetry. The key concerned content: model and calibration of the digital imaging device, high preecise image processing algorithm, optical coding and precise optical probe are discussed in details, and the implement idea is also presented, these can provide design reference for industry on-field close range photogrammetry 3D precise measurement system.
