At present, the better companies in China are Daheng and Lingyun. I'm not familiar with the market in Chongqing, but as far as the domestic machine vision market is concerned, I think the best companies are Shenzhen and Shanghai. Because there are many processing plants and a lot of project experience in these places. When it comes to machine vision products, I don't think Daheng's is so good (patriotic, their products are independently developed. Because the current machine vision products are still foreign brands, the effect and quality are very good. Therefore, the products of foreign brands represented by these companies are generally good, and of course the prices are also good.
Of course, I have to mention cognex. He is the world leader in vision, the project can be solved, and the product cost performance is not expensive.
Generally speaking, the domestic machine vision market has just started, and the mainland can't keep up now, so stick to it.
I have answered your question.
