摘要
结合线阵相机的成像特点以及正在研制的车载三维数据采集系统本身的特性,提出一种利用激光扫描数据为基准,标定线阵相机内参数的技术方法,以实现激光扫描数据和线阵相机扫描影像精确对准。应用激光扫描仪原始数据中的角度信息,结合线阵相机的成像原理,建立线阵相机的内参数标定模型,并设计相应的试验方法,计算出了高精度的畸变参数,为实现真实纹理映射奠定基础,为同类产品的检校提供参考。
Based on the characters of the line scan camera and the vehicle-borne 3D data acquisition system,this paper presented a method to calibrate the line scan camera（LSC） based on the laser scanner.Using the angle information in the original laser scanner data,combing the principle of the line scan camera,it built a calibration model for LSC and designed some experiment methods for that.Then it computed high precision calibration parameters,which provides basis for the texture mapping in the future and gives references to the similar sensors calibration.
