摘要 介绍了利用 863项目“机载激光影像制图系统”获得的激光测距数据 ,飞机 GPS位置数据和姿态数据进行 3维直接对地定位的一系列技术 ,及其在计算机视觉方面的应用 [1]。致力于解决如下 3个方面的问题 :1 .如何解算激光测距点末端的 3维坐标 ;2 .如何解算已识别目标 (高程已知 )中每一点的 3维坐标 ;3 .影像存在扭曲 ,如何将现实空间中的直线映射成影像空间中的曲线。本文方法适用于线扫描方式与圆扫描方式。 This paper introduces a series of 3D positioning techniques by utilizing the laser ranging data, the GPS data, and the attitude data from “Airborne Laser ranging and Multi spectral Imaging Mapping System”, and their application in computer vision, such as automatic buildings extraction. The techniques try to deal with such problems: 1. How to compute the 3D coordinates of the laser ranging points? 2. How to compute the 3D coordinates of an extracted object with known height? 3. Since the distortion of the image changes a straight line in the physical space into a curve on the image, how to compute the curve?
