Embodiment Construction

[0014] The logical structure block diagram of the innovative experimental platform of the present invention is shown in FIG. 1 , including a speed-adjustable motor 5 arranged inside the chassis 1, which is used to drive the circular inspection table base 7 on the chassis 1 to rotate at a constant speed through the transmission mechanism 6, so that the The test sample 8 on the inspection table base 7 is aligned with the camera 10 . The speed control knob 3 is set on the chassis panel, and the speed of the motor 5 is adjusted according to the requirements of the test task.

[0015] Several marks are engraved on the base 7 of the inspection table, and the tested sample 8 is placed at the marked position. A photoelectric sensor 4 is installed inside the chassis 1. During the rotation of the inspection table base 7, when the photoelectric sensor 4 detects the marked position, it indicates that the sample under test 8 is directly under the camera 10, and the photoelectric sensor 4 s...

Abstract

The invention discloses an innovating experiment platform for the machine vision teaching, which comprises a machine case, a power button, a speed adjustment knob, a photoelectric sensor, a motor, a transmission mechanism, an inspection table base, an annular light source, a camera, a camera bracket and an image processing unit, wherein, the power button controls the power supply of the whole system, a variety of arithmetics used for realizing the machine vision teaching innovating experiment are arranged in the image processing unit, an mage processing software platform comprises a code window, a parameter window, an image window and a variable window; twenty innovating experiments with different difficulty degree are provided, which comprises ten image measuring and treating foundation experiments, five pattern recognition experiments and five machine vision field study hot point problems. Through the experiments, students can thoroughly understand and firmly grasp the basic theoretical knowledge relative to the machine vision, image measuring and pattern recognition aspects, and has direct experience to the product vision detection and determination simulation process of an industrial automatic production line and improves the ability of independently solve the technical difficult problem.

Description

technical field [0001] The invention belongs to the technical field of machine vision image measurement and pattern recognition, relates to an experimental platform, and further relates to an innovative experimental platform for machine vision teaching. Background technique [0002] In recent years, with the rapid development of image processing and pattern recognition technology, major colleges and universities have successively opened courses related to image processing and machine vision. Such courses not only require students to master the basic theoretical knowledge of image processing, but also require students to be able to Use image processing methods to solve some practical problems, such as size measurement, classification and identification of workpiece products, product surface defect detection, license plate number recognition, barcode recognition, etc. Whether it is undergraduate teaching or postgraduate teaching, most colleges and universities currently only s...
