 note = {Limited by the poor vertical resolution of multi-laser LiDAR sensors like Velodyne HDL-32E, the sparsity of 3D points increases drastically in vertical direction as the distance from Velodyne increases. Interpolating in the point cloud is a method that often used to solve this problem. In this paper, we propose a mobile system consist of a Velodyne LiDAR sensor and a panoramic camera(we utilize a Ladybug3 panoramic camera here) for indoor mapping. We call it Velobug(Velodyne and Ladybug) system for practical purpose. Velobug can be used to obtain denser points clouds by deflecting Velodyne and rotating it around plumb line. Also with the Ladybug3 panoramic camera under Velodyne, we can get a colored point cloud by corresponding each 3D point to a pixel on the panoramic image acquired from Ladybug3 after the calibration of Velobug. Generalized Iterative Closet Point(Generalized-ICP) is adopted in frame-to-frame registration of the point clouds for indoor mapping., Limited by the poor vertical resolution of multi-laser LiDAR sensors like Velodyne HDL-32E, the sparsity of 3D points increases drastically in vertical direction as the distance from Velodyne increases.
