A novel method for projecting points onto a point cloud, possibly with noise, is presented based on the point directed projection (DP) algorithm proposed by Azariadis P., Sapidis N. [Drawing curves onto a cloud of points for point-based modelling. Computer-Aided Design 2005; 37(1): 109–22]. The new method operates directly on the point cloud without any explicit or implicit surface reconstructi...

3D object recognition is a basic research in the machine vision field. Microsoft KINECT V2 is utilized to collect external environmental information. The point cloud file is obtained after processing the collected information. In order to filter the point cloud and obtain point cloud model of a single object in the environment after region growing segmentation, the point cloud is applied to poi...

The alignment, or rigid registration, of three-dimensional (3D) point clouds plays an important role in many applications, such as robotics and computer vision. Recently, with the improvement high precision automated 3D scanners, registration algorithm has become critical a manufacturing setting for tolerance analysis, quality inspection, reverse engineering purposes. Most currently developed a...

How will you repair a physical object with large missings? You may first recover its global yet coarse shape and stepwise increase local details. We are motivated to imitate the above procedure address point cloud completion task. propose novel network (SPCNet) for various 3D models missings. SPCNet has hierarchical bottom-to-up architecture. It fulfills in an iterative manner, which 1) infers ...
