Abstract

The invention discloses a method for detecting product quality through three-dimensional reconstruction. The method includes: installing a Kinect device on a movable platform, and the platform can perform circular motion around a fixed circle center, and the shooting direction of the Kinect device faces the fixed circle center; A rotating steering gear is built at the center of the fixed circle where the platform moves, and the target object is fixed on the rotating end of the rotating steering gear. The rotating steering gear can drive the target object to rotate in the vertical direction; connect the computer installed with VTK to the Kinect device , use the Kinect device, and obtain the point cloud data of the target object through the rotation of the mobile platform and the rotating steering gear. According to the obtained point cloud data, the 3D model of the target object is drawn through VTK, and the image feature matching algorithm is used to achieve the target object. Quality inspection of target objects. Therefore, the quality problems of products on the 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...
