The current types of the multi-layer lidar sensors are expensive. Besides, these types of lidar are not able to scan the above space because of the limited pitch angler movement, which leads to uncompleted three-dimensional (3-D) spatial reconstruction. This paper proposes an approach to solve these problems fusing the point cloud data from a single-layer lidar and yaw angler data from a stepping motor. The three-dimensional normal distribution transforms (3D-NDT) registration algorithm shows higher accuracy than iterative closest point (ICP) one in this application. The experiments show that this approach represents a full field spatial reconstructing method along with region of interest (ROI) scanning. The 3D-NDT algorithm is employed in this approach that shows a robust registration result.
