摘要 全景影像与激光点云的高精度配准是车载移动测量系统中多传感器数据集成处理的关键环节。本文针对车载多面阵拼接全景影像与激光点云的配准问题,提出了一套高精度的数据配准方法。通过高密度的静态激光点云解算每个面阵CCD在激光扫描仪坐标系下的外标定参数,以实现单张CCD影像与激光点云在扫描仪坐标系下的配准,在全景拼接过程中全景影像与单张CCD影像精确的映射关系已知,利用扫描仪坐标系、POS坐标系及WGS-84坐标系间的转换关系即可获得全景影像与激光点云在物方坐标系下的动态、高精度的配准参数。试验表明该数据配准方法精确可靠、适用性强,能满足基于全景影像与激光点云数据融合的城市道路竣工、部件采集、目标提取、三维重建等高精度量测应用需求。
