英文摘要：

Present condition at home and abroad and open question of calibration technique based on three--dimensional measuring system are introduced. At the same time, the author propounds a sort of Auto--calibration technique which is named multiple target tracking for checking outline based on random placement and regular number. In addition, concrete arithmetic is given. Secondly, according to the arithmetic, relevant experimental result is gained. Furthermore, the result＇s precision is analyzed. Finally, a conclusion shows that the operation is simplified and orientation precision of edge of image outline is ensured by the arithmetic. Moreover, calibration precision is kept within 0. 02-0. 05 mm.
