| 摘 要： | 照相机标定是进行交通事故现场照相测量的首要工作。相机标定的Tsai两步法是一种理论上的探讨，缺乏方法的完善性和完整的标定程序以及实际验证。对Tsai标定法进行了改进和完善，提出了完整的标定步骤，编制了相应的标定程序，并用实倒对标定方法和程序进行了验证。

| Abstract: | Determining a set of camera parameters is the first task of measuring with camera in traffic accident field. Tsai method is a method in theory without perfect calibration procedure and validation. Under improving on Tsai method, it puts forward a perfect calibration steps, the whole calibration procedure showing the whole calibration process, and validates the arithmetic in the traffic accident field measuring with example. |
