Abstract

The invention provides a test paper sorting system and method based on machine vision. The test paper sorting system comprises a conveying device, a camera obscura, a camera, a sorting device, lighting equipment and a controller. The sorting method mainly comprises the steps of image acquisition, image preprocessing, inclination correction, template matching, image recognition, sorting and the like. Automatic detection and sorting of test paper on a production line can be realized, so the sorting efficiency and accuracy are greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a test paper sorting system and sorting method based on machine vision. Background technique [0002] During the production process of the test paper, it is usually necessary to pack the test paper in a test paper bag or a test paper box in a certain order. For the test paper bags or test paper boxes that are put in the wrong order, they are mainly checked and sorted manually. The manual method has the following disadvantages: the difference between some test papers is very small, and the workers need to have skilled operation skills; the size of the test paper and The words printed on it are usually very small, and workers are prone to eye fatigue and make mistakes; a bag or a box of test strips usually contains many pieces of test strips, and it is difficult for workers to quickly check a bag or a box of test strips, so a large number of workers are usually required, thereby impro...
