Systems and methods for constructing a three-dimensional panorama model of an object are disclosed. An exemplary system includes a storage device configured to receive a plurality of point clouds each acquired at a different view angle. Each point cloud includes three-dimensional positions of a plurality of target points on a surface of the object. The system further includes at least one processor configured to determine elevation and normal at each target point in each point cloud and convert the elevation of each target point to color information. The at least one processor is further configured to register every two adjacent point clouds among the plurality of point clouds based on the three-dimensional positions, the normal, and the color information of the respective target points of the two adjacent point clouds. The at least one processor is also configured to render the three-dimensional panorama model based on the registered point clouds.
