摘要
为了对轨道检测系统中的线阵相机进行标定,文章设计出了一种高精度标定装置,建立了标定系统的非线性的数学模型。使用实验采集到的数据对该模型进行迭代求解,可以求出相机内部和外部的参数。经过验证,数学模型和标定设备精度较高,标定误差在±0.5mm以内。
In order to calibrate linear array CCD cameras in high-speed rail detection system,we designed calibrationdevices and proposed a accurate mathematical model.By using data collected in experiments,we can resolve the internaland external parameters of the cameras.The calibration results show that the data we collected by our device are wellmatched with the model,and the errors are between±0.5mm.
