能否快速、经济、准确地获取地理空间信息取决于车载移动测量系统( MMS)性能的优劣。针对当前车载移动测量系统存在的精度不高、价格昂贵、灵活性不高、检校麻烦等一系列问题，利用低成本硬件，包括无人车、GPS/IMU模块、数码相机、RGB-D相机、太阳能移动电源等，设计出了一种经济高效、适用可靠的多源多目视觉无人车移动测量系统，可为数字城市的建设提供一条经济适用且便捷高效的目标物空间信息获取新途径。%The performance of vehicle mobile measurement system ( VMMS) determines whether it can obtain the spatial infor-mation quickly and accurately. In view of the currently existed problems of vehicle mobile measurement system, namely lower ac-curacy, expensive, poor flexibility, fussy check and calibration, a new type of VMMS was designed with some low cost hardware, such as automated vehicle, GPS/IMU module, digital camera, RGB-D camera and solar mobile power sources. The practice proves that this system is efficient and practical, which can provide a new method to obtain spatial information of target economi-cally and effectively for digital city construction.
