In order to enhance the instantaneity of SLAM for indoor mobile robot, a RGBD SLAM method based on Kinect was proposed. In the method, oriented FAST and rotated BRIEF(ORB) algorithm was combined with progressive sample consensus(PROSAC) algorithm to execute feature extracting and matching. More specifically, ORB algorithm which has better property than many other feature descriptors was used for extracting...
Two hybrid methods, rank integration and hierarchical methods, are proposed for 3D model retrieval by using features based on geometric ratios and statistical information. Both methods are capable of taking advantage of each single retrieval method very well. A contrast experiment for the hybrid methods, single retrieval methods, and weighted method is conducted. Experimental results show that, the...
Case based design is an effective method to reuse existing resources in an enterprise. The similarity between 3D models of parts is measured by shape distribution method. Fuzzy c-means clustering algorithm is applied to classify products 3D models. The classes of 3D model form high dimension Euler space and the vector space model is used to represent the product case. The process to construct product...
