A Method for Automatic 3D Measurement of Unknown Objects Based on the Structured Light System

This paper proposes a novel approach to determine three-dimensional (3-D) model from a minimum number of viewpoint of an object. Calculating the position relation location of two coordinate system in order to splice the multi- view point cloud. The Next Best Views (NBV) is calculated by the visibility classification and Mean-shift algorithm and then the overall morphology of the measured object can be acquired. The view planning method not only reaches a fast measurement speed, but also possesses a high fidelity to the complex regions of the measured object by the experiments.
