摘　　要：介绍了目前基于三维光栅扫描测量标定技术的国内外发展状况，提出自由置位固定编码多目标跟踪提取连续图像轮廓的全自动标定技术，同时给出了此技术的具体算法实现。利用本文提出的全自动标定技术。得出了相应的实验结果。并将该实验结果与利用通用的MARR算法得到的结果对标定精度进行了比较、分析。最后。得出本文所提出的全自动标定技术不仅可以使操作更加便捷，而且能够很好地保证标定图像轮廓边缘的定位精度。同时使整个系统的标定精度保持在0．005—0．02mm范围内的结论。This paper introduced nowadays conditions of calibration technology based on three - dimensional measuring at home and abroad. At the same time, the author propounded a sort of auto - calibration technology, which was named multiple target tracking for checking outline, based on random placement and regular code. In addition, the author gave a concrete arithmetic. Then, according to the arithmetic, the author gained relevant experimental result. Furthermore, the author compared and analyzed the calibration precision between the arithmetic and MARR arithmetic. Finally, the author arrived at a conclusion that the operation was simplified and orientation precision of edge of the calibration image outline was ensured by the arithmetic. Moreover, the calibration precision was kept within 0. 005 -0. 132 mm
