摄影测量中编码标志点设计方案概述
|
摘要
大尺寸三维测量中,通常在被测物体表面设置一些具有唯一特征的编码标志点,通过解码可实现不同图像中同名点的匹配。本文首先介绍了摄影测量技术中编码标志点的作用和分类,分析了点状编码标志点和环状编码标志点的编码原理及存在的问题,总结了各种改进方案的特点,然后根据编码标志点的设计要求讨论了两类编码标志点的特点,最后对编码标志点的设计提出了一些改进思路。
Some coded marker points with unique features are usually set on the surface of the measured object in large-scale 3D measurement. The decoding can achieve fast and accurate matching of points of the same name in different images. This article summarizes the research of coded marker points design from the following aspects: requirements for coded marker points design,the encoding principles of point-coded marker points and circular-encoded marker points,and the characteristics of different improved methods of circularly encoded marker points.At last we discussed the advantages and disadvantages of the two types of coding points according to design requirements and put forward some ideas to improve the design of circular coding marker points.
