Embodiment Construction

[0028] Such as figure 1 As shown, the multi-camera visual inspection system provided in this embodiment includes a plurality of miniature cameras 1 and an image processing unit 2 . Multiple micro-cameras 1 are arranged around the detected object 100 , and the multiple micro-cameras 1 acquire multiple images of the detected object 100 by auto-focusing. The image processing unit 2 is electrically connected to a plurality of miniature cameras 1, and matches the acquired images with the preset corresponding image templates; when all the images match the preset corresponding image templates, it is judged that the detected object It is a qualified product, otherwise, it is judged that the detected object is a non-conforming product.

[0029] The multi-camera visual inspection system provided in this embodiment is provided with a plurality of miniature cameras 1, and each miniature camera has an auto-focus function. When the detected object has multiple planes with different height...

Abstract

The invention provides a multi-camera vision detection system and detection method. The detection system comprises multiple miniature cameras and an image processing unit. The multiple miniature cameras are arranged above a to-be-detected object and obtain a plurality of images of the to-be-detected object in an automatic focusing manner. The image processing unit is in electric connection to the multiple miniature cameras and matches the obtained images with a preset corresponding image template. When all the images match the preset corresponding image template, the to-be-detected object is judged as a qualified product, or otherwise, the to-be-detected object is judged as an unqualified product.

Description

technical field [0001] The invention relates to the field of product detection, and in particular to a multi-camera visual detection system and detection method. Background technique [0002] With the continuous advancement of computer technology, the detection of industrial products has been gradually converted from traditional manual detection to automatic detection of automated equipment. Automatic detection not only greatly reduces the cost of manual detection, but also improves the detection efficiency of products to a certain extent. [0003] The existing automatic detection method is that a single CCD camera on the automatic equipment acquires the image of the detected object, and compares the obtained image with the standard image. When the two are the same, it is considered a qualified product, otherwise, it is a non-conforming product . Since a single CCD camera can only clearly capture the image of a certain plane of the detected object, and for the detected obj...
