【摘要】 针对车载移动测图系统无控制点成像的特殊要求,设计并实现了一种基于 IMU/GPS 的车载移动测图系统用高性能位置姿态系统;采用了前向滤波和后向平滑的后处理方法,以提高 POS 系统精度。最后,进行了车载成像试验,试验结果表明,该系统可以满足车载移动测图系统对 GPS 失锁2min 定位误差小于2m 的精度要求。更多还原

【Abstract】 Aiming at the special requirements of Mobile Mapping System which imaging without control points,a high-performance Position and Orientation System is designed and realized based on IMU/GPS.In order to improve the precision of the system,post-processing method including forward filter and backward smoothing is adopted.Finally,the results of imaging tests indicate that the system can meet the requirements of the MMS,and the position error is within 2 meters during GPS outage periods for 2 minutes.更多还原
