摘　　要：针对目前多相机摄影测量系统中相机标定技术研究较少，而且其标定方法的可靠性、稳定性以及标定精度针对高精度工业测量检测要求存在缺陷的问题，将四元数理论引入共面条件方程，提出了一种三目立体摄影测量系统的标定技术，有效解决了多相机立体摄影测量在工业测量现场高精度实时标定问题，实现点位精度优于±2mm，距离精度优于±3mm。Aimed at the problems that it is lack of the study on camera calibration of inore-cameras stereophotogrammetry,and it is no way to satisfy the need of the high precision industrial measurement via the reliability andstability and the precision of the presently technique. Base on the quaternions theory and coplanarity equation,and the newtechniques of camera calibration in the trinocular stereo photogrammetry system is proposed,which efficaciously resolves thequestion of the real-time high precision calibration in industrial field measurement, and the measurement precision ofcalculated object points coordinates （R_MS） is better than ±2 mm,the distance precision is better than ±3 mm in the test.
