A kind of object scanning modeling method and its application

Abstract

The invention discloses a physical scanning method. The physical scanning method comprises the following steps that a modeling robot is equipped, modeling equipment is arranged on the modeling robot,a modeling visual sensing camera and a posture sensor are arranged on the modeling equipment, a modeling working table is arranged on the side of the modeling robot, a workpiece is placed on the modeling working table, and a plurality of constraint points are arranged, so that the modeling robot drives the modeling equipment to sequentially pass through the constraint points in a specified path and a specified posture, the workpiece is photographed, and all image data and posture data are integrated, a physical three-dimensional model of the workpiece is generated. The posture sensor can sensethe posture of the modeling visual sensing camera when taking photos. The posture sensor can enable the posture setting of the modeling robot to be more in line with the setting requirements, the requirements on the own motion accuracy of the modeling robot is greatly reduced, and the calculation amount of a driving system is reduced. Finally, high-efficiency and high-precision physical modelingis realized. The physical scanning method is used for physical scanning modeling.

Description

technical field [0001] The invention relates to the field of three-dimensional scanners, in particular to a physical object scanning modeling method and its application. Background technique [0002] A 3D scanner (3D scanner) is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. [0003] The collected data is often used for 3D reconstruction calculations to create digital models of actual objects in the virtual world, and these models have a wide range of uses. [0004] Existing 3D scanners are either hand-held, or set up a guiding structure so that it has a specific scanning trajectory, but the scanning accuracy of the hand-held scanner is poor, the workload is heavy, the time is long, and professional training is required, while it has a specific It is difficult for a scanner that scans a trajectory to perform a complete scan of some comp...
