摘要
本文给出了一种基于车载的激光点云与线阵CCD相机图像进行数据融合的方法。车载数据采集系统集成了GPS,激光扫描仪,IMU和线阵相机。该方法基于POS的定位定姿数据,利用时间信息和各个传感器的相对空间位置信息建立激光点与CCD相机扫描线之间的对应关系,进而确定CCD扫描线上与该激光点对应的像素。将该像素的颜色属性赋给激光点,可得到具有颜色属性的三维激光点云。最后给出具体融合结果。
An algorithm to integrate laser points and CCD images was presented. The data collection system includes GPS, LS, IMU and CCD line camera. The algorithm found the CCD image＇s scan line for each laser point, and then found the sequence number of the pixel on the scan line for the point by the pose of the system which is offered by POS and corresponding time and space of the sensors. The pixel＇s color is set to the point. A real colored point cloud is given at last.
