提出一种带有微小转角修正的车载激光成像系统外方位元素标定方法。针对全球定位系统(GPS)、惯性测量单元(IMU)和激光扫描仪(LS)集成的车载激光成像系统(车载移动测绘系统),该方法使用6个微小旋转角参数和6个微小平移参数对传统标定模型参数进行修正。试验数据表明,方法可对系统的安装误差和时间同步误差进行有效改正。 更多还原

【Abstract】 A calibration method with small rotation-angle corrections for the exterior orientations of vehicle laser imaging system was proposed.In the vehicle laser imaging system,mobile surveying and mapping platform system(MSMP),integrated GPS with both IMU(inertial measurement unit) and LS(laser scanner),the method used six small rotation-angle parameters and six small translation parameters to correct the parameters of traditional models.The experiments show that the new method efficiently corrected t... 更多还原
