Abstract

The present invention relates to a method and a system for three-dimensional automatic scan based primitive, and estimates a three-dimensional model of an object from three-dimensional scan data of the object, recognizes a shape of the three-dimensional model by using fitting with at least one primitive, evaluates confidence of each of surface points of the three-dimensional model based on similarity between the at least one primitive used for shape recognition and the shape of the three-dimensional model, and scans the object in a series of views determined based on the confidence of each ofthe surface points, and thus, accuracy of the three-dimensional scan of the object is improved and time required for scan may be reduced.

Description

technical field [0001] The present invention relates to a three-dimensional automatic scanning method and system for automatically and repeatedly performing three-dimensional scanning of an object until the reliability is satisfied. Background technique [0002] A 3D scanner is a device that uses an image sensor to generate a 3D model representing a 3D shape of an object. The three-dimensional scanning method is divided into a manual method in which a person holds a scanner and adjusts its position to scan various parts of the object, and an automatic method in which a robot or the like automatically adjusts the position of the scanner or the object to scan various parts of the object. In the manual method, since personnel arbitrarily judge and set the position of the scanner, the accuracy of the scanned data is low and there are many unnecessary repeated scanning. [0003] Although the automatic method can solve the problem of the manual method to a certain extent, it adju...
