摘要
本文针对近景摄影测量中编码标志点数目不能满足缺乏纹理的较大区域、大尺寸及复杂物体测量需求的问题,深入分析研究了国内外现有编码标志设计和解码方案,提出了一种具有编码起始标记的条形码设计方案,使得其编码总数得到扩展,并设计了相应的解码算法;最后制作编码标志实物在室内实验室进行场景实拍实验,各项实验结果数据证明课题的研究成果可以满足工程中的实际需要。
Aiming at the problems of coded targets which can not satisfy large determined area where lacks in textures,objects are big and complex in close-range photogrammetry,this paper analyzed the design thinking and decoding strategy of barcode encoding target at home and abroad,and finally proposed a design with a beginning circle target and decoding method for barcode target,which made its number enlarged a lot.What＇s more,the decoding process in real scene image experiments was developed and tested,and these result data proved that this research could fulfill practical projects.
