Machine vision market size
Machine vision has been widely used in industries such as industry, agriculture, defense, military, transportation, medical, finance, and even sports, entertainment, etc., and will revolutionize our lives, production, and work.
According to the analysis of foreign research institutions MarketsandMarkets, the global machine vision market will be US$8.08 billion in 2015. By 2020, the market size will reach US$125 billion. The global machine vision market will grow at a compound annual growth rate of 9.1% from 2016 to 2020.
China's machine vision industry started late, the market base is small, but the development speed is fast (into the rapid development period after 2009), and it has become the world's third largest machine vision market after the United States and Japan.
In 2015, China's machine vision market reached 6.12 billion yuan, a year-on-year growth rate of 28.57%, the fastest growth rate in the world, far higher than the global average. It is expected that China's manufacturing will maintain a 20% growth rate for machine vision from 2016 to 2020, and the market size will reach 15.2 billion yuan by 2020.
Machine vision system
Machine vision is to use the machine instead of the human eye to make measurements and judgments. Machine vision system refers to the conversion of the ingested target into an image signal by machine vision products (ie, image capture device, divided into CMOS and CCD), and transmitted to a dedicated image processing system, which is transformed according to pixel distribution, brightness, color, and the like. Digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the action of the device on the basis according to the result of the discrimination.
Machine vision systems involve multiple technologies. The most basic systems also require lighting, imaging, image digitization, image processing algorithms, computer software and hardware. A slightly more complex system will also use mechanical design, sensors, electronic circuits, PLCs, Motion control, database, etc.
In the entire machine vision system, semiconductor components and software development account for 80% of the cost, of which imported core components and underlying software development account for 60% of production costs.
