摘要
主要阐述可量测立体像对的3D立体坐标量测系统设计与实现。现存的全数字摄影测量产品要么是价格昂贵的高端专业设备(一般为具有高端图像卡的工作站),要么是功能受约束的简单设备。将说明如何在非高端图形PC设备上,运用面向对象程序设计、OpenGL、软件模块化和硬件无关性等技术实现所要求的立体量测系统功能。
In this text, a stereo system designed and used for the measurement of 3D-coordinates within metric stereo image pairs will be presented. As the systems which have been developed up to now are either very special ones, founded on high-end graphics workstations with an according pricing or simple ones with restricted measuring function, a new conception will be shown, which avoiding special high-end graphics hardware but providing the measuring function required. The presented stereo system is based on PC-hardware equipped with a graphic PC and uses an object oriented programming, modularity and hardware independence technique.
