3D modeling based on point clouds is an efficient way to reconstruct and create detailed 3D content. However, the geometric procedure may lose accuracy due to high redundancy and no explicit structure. In this work, we propose a human-in-the-loop sketch-based point clouds reconstruction framework to leverage the users’ cognitive ability in geometry extraction. We present an interactive drawing interface for 3D model creations from point cloud data with the help of user sketches. We adopt an optimization method that the user can continuously edit the contours extracted from the obtained 3D model and retrieve the model iteratively. Finally, we verify the proposed user interface for modeling from sparse point clouds.
