Abstract

The invention discloses a method of detecting product quality through three-dimensional reconstruction. The method includes the following steps: mounting Kinect equipment on a movable platform, wherein the platform can perform circular motion around a fixed center of circle, and the shooting direction of the Kinect equipment is toward the fixed center of circle; establishing a rotary steering engine in the fixed center of circle where the platform is moving, fixing an object on a rotary end of the rotary steering engine which can drive the object to rotate in a vertical direction; and connecting a computer equipped with a VTK to the Kinect equipment, using the Kinect equipment, obtaining point cloud data of the object through the movable platform and rotation of the rotary steering engine, drawing a three-dimensional model of the object through the VTK on the basis of the obtained point cloud data, and detecting the quality of the object through an image feature matching algorithm. Therefore, the quality of products on a production line can be detected in real time.

Description

technical field [0001] The invention relates to the field of product quality detection, in particular to a method for detecting product quality through three-dimensional reconstruction. Background technique [0002] In the process of product testing, at present, a large number of human resources are mainly used to conduct random sampling inspections on products to achieve the purpose of product quality testing. In this process, it is inevitable that substandard products will flow into the market, resulting in a bad reputation of the product and unnecessary after-sales problems. [0003] Therefore, a more scientific product quality detection method is provided, which can detect the quality problems of products on the production line in real time, and this method is an urgent problem to be solved by the present invention. Contents of the invention [0004] The object of the present invention is to provide a method for detecting product quality through three-dimensional reco...
