Description

Technical Field

[0001] The utility model relates to the technical field of machine vision, in particular to a recognition device based on machine vision. Background Art

[0002] Machine vision is a rapidly developing branch of artificial intelligence. Simply put, machine vision is the use of machines instead of human eyes to make measurements and judgments. The machine vision system converts the captured target into an image signal through machine vision products, transmits it to a dedicated image processing system, obtains the morphological information of the captured target, and converts it into a digital signal based on pixel distribution, brightness, color and other information. The recognition device based on machine vision is a turnstile. The turnstile is a channel blocking device used to manage the flow of people and regulate the entry and exit of pedestrians.

[0003] When the existing recognition device is used, the recognition interval is short when there are many people passing through, which makes it impossible for people to grasp the closing time of the gate, causing the gate plate to hit the legs of people and cause injuries. Therefore, a recognition device based on machine vision is proposed to solve the above problem. Utility Model Content
