Abstract: Combining terrestrial laser point cloud and fisheye image are high efficiency on panoramic information analysis. Registration of fisheyes panoramic image and terrestrial LiDAR data is a prerequistite for its information complement each other. But it is necessary to overcome the difficulties of data dimensional difference transformation and feature matching. In this paper, a new semi-automatic method is brought up to registered these two data based on Hough algorithm, both fisheyes image and LiDAR points are reprojected to a same cylindrical surface. Line features are extracted from these two images based on Hough algorithm. And then, the modified Iterated Hough transform is employed to registered LiDAR range image and fisheye cylindrical surface image. Experimentation shows that the model has capability to register these two data in 3D screen with less manual intervention, and obtain high register precision within the area near fisheyes image viewing point.
