摘要

对带自标定的束平差作了基本评述。介绍了标定与定位的数学模型、参数估计和质量分析。描述了使用现成的CCD(电荷耦合器件)相机、镜头和帧采集器进行精度调查的校准程序、硬件和测试场。经经纬仪独立测量,物象空间的相对精度为1/ 30000,影像空间的相对精度为1/45。

Accurate calibration of CCD-cameras
A basic review of the bundle adjustment with self-calibration is given. The mathematical model, parameter estimation, and quality analysis of calibration and positioning are covered. The calibration procedure, hardware, and testfield of an accuracy investigation with off-the-shelf CCD (charge-coupled device) camera, lens, and frame grabber are described. A relative accuracy in object space of 1 part in 30000 and an accuracy of 1/45 in image space were verified by independent measurements with theodolites.<>
