Abstract

The invention discloses a product morphology detecting method based on Kinect. According to the method of the invention, three-dimensional reconstruction is performed on a product in a streamline by means of Kinect deep sensing equipment, and then the reconstructed model is compared with a preset product model for determining whether the product is a qualified method. The product morphology detecting method is advantageous in that a new improvement method is presented for multi-camera calibration, namely a cylinder manner is utilized for calibration; and a rotation translation matrix of the camera can be obtained accurately in higher speed. Compared with a method for performing integral filtering processing on a depth image for eliminating holes, the product morphology detecting method isadvantageous in that a target area is preliminarily selected by means of a rectangular block; and then an improved K-means clustering method is utilized for sufficiently eliminating product backgroundnoise and effectively extracting the product morphology. Compared with a traditional product detecting method, the method according to the invention has advantages of easy configuration, simple structure, high practicability, high speed and remarkable enterprise production cost reduction. Furthermore an error detecting rate of the product is reduced to a certain extent.
