Abstract

The apparatus comprises the camera composed of the black or color linear CCD chip integration board (including A / D converter, RAM, PLD, I / O port and USB port), optical system (lens and light source), data collecting card, computer, light barrier board having tunable margin and glare shade. The camera is located at one side of manufactured products, and the manufactured products are exposed through a direction-tunable light source, and then the reflected light is coupled into the CCD sensing surface through the lens. The components in the integration board complete the A / D conversion, image processing and transmission. Through the image collecting card the images are transmitted to the computer to implement the saving of consecutive image. It can be used for field supervision, the PLD can make pre-process for the defect in collected image and send alarm signals. The consecutive image saved in the computer can provide a reference for the product classification.

Description

technical field

[0001] The invention relates to a method and a device for collecting large-format industrial product images by using a linear array CCD (Charge Coupled Device), belonging to the technical field of computer vision. Background technique

[0002] In many industrial sites, it is necessary to automatically detect the surface of industrial products, and analyze the images of industrial products after collecting them, so as to guide the production of products, such as grading, grading, and alarming. Some industrial products have a large size and format, such as rolled steel strips, printed and dyed textiles, printed printed matter, and wood rotary-cut veneer strips, etc., and some of their format sizes can reach more than 3000mm. At present, the identification of industrial product defects in many fields is still carried out manually, which has caused a bottleneck in the automatic production of products. At the same time, the accuracy of manual identification is low...
