In recent years, machine vision has been widely used in industries such as industry, agriculture, national defense, military, transportation, medical, finance, and even sports, entertainment, etc., and will revolutionize our lives, production, and work. It is reported that machine vision started late in China and officially entered the high-speed development period after 2009. At present, China has become the world's third largest machine vision market after the United States and Japan. In 2015, the scale of China's machine vision market has reached 6.12 billion yuan, China's manufacturing is expected to maintain a 20% growth rate in machine vision between 2016 and 2020. By 2020, the market size will reach 15.2 billion yuan. Machine vision is to use the machine instead of the human eye to make measurements and judgments. The working principle of the machine vision system: through the machine vision product (ie, the image capture device, which can be divided into CMOS and CCD), the captured target is converted into an image signal and transmitted to a dedicated image processing system, according to pixel distribution and brightness, color. The information is converted into a digitized signal; the image system performs various operations on the signals to extract the features 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. Let's summarize the mainstream machine vision image processing technology solutions. The Accordo 5 product family is the latest generation of ST's successful Accrodo product line, integrating the ARM® Cortex®-A7 processor with parameters that are ahead of other brands of digital infotainment chips on the market. The Accordo5 family offers designers a variety of configuration options, with the single-core Cortex A7 supporting external 16-bit high-performance DDR3 memory and the dual-core Cortex-A7 supporting external 16- or 32-bit high-performance DDR3 memory. Graphics and audio and video capabilities are the most prominent features of Accordo 5, although the main mid-range automotive market, but the 500MHz 3D graphics processor core makes its graphics processing performance far superior to its peers. The system architecture supports 2D and 3D graphics at 1080p resolution. Common formats include OpenVG and OpenGLES-2.0 with graphics effects. High-performance audio DSP, six stereo analog channels and audio interfaces supporting multiple industry standards, built-in display controller supports full HD resolution TFT-LCD touch screen. High-performance audio and video processing can be embodied, such as displaying user interface, reversing images, navigation maps, and video previews simultaneously. The playback function supports major video encoding formats such as H.264 and DivX®, as well as 2D and 3D graphics involving graphics blending and overlaying. The new product provides a USB interface and an SD memory card interface. In addition, the Accordo 5 Series allows smartphones to interact with the in-vehicle system, screened on the car display screen for secure viewing or use of content on the phone, such as music and navigation services. In addition, in terms of security, an ARM Cortex-M microcontroller is integrated internally to manage the security of the CAN interface between the digital instrument panel and the car's main network. The Accordo 5 chip integrates three CAN ports, one of which supports the latest CAN FD high-speed transmission standard, the on-chip hardware cryptographic accelerator supports SHA-2, PK and AES encryption algorithms, and the one-time programmable (OTP) memory is used to store the master key. Prevent data from being tampered with. The microcontroller's standby current is extremely small, and the power consumption of the entire chip is carefully optimized to minimize battery consumption in the car. The Accordo 5 product family consists of three products, STA1275, STA1285 and STA1295. Among them, STA1295 is equipped with dual-core Cortex-A7 processor and is available in 19mm x 19mm x 1.7mm LFBGA529 package. The Xilinx All Programmable solution and the Zynq®-7000 All Programmable SoC platform support a variety of machine vision interfaces such as GigEVision, LVDS-based CameraLink and emerging USB3 technology. Single-chip processing provides a highly flexible IO architecture, while the dual-core Cortex A9 processor supports analysis and system software. Xilinx Smart Solutions includes not only All Programmable FPGAs and SoCs, but also a range of customizable SmartCORE and LogiCORE IP cores to meet your unique market needs. Xilinx Vivado® Design Suite works with highly integrated development tool flows and uses OpenCV libraries, Vivado high-level synthesis and IP Integrator to deliver the most differentiated products to the market faster and more flexible than AISC and ASSP solutions. At the same time reduce risk and cost of ownership. The following diagram demonstrates an example of image processing, analysis, custom IP, and a highly flexible machine vision interface on a single chip that significantly reduces bill of materials costs and significantly improves system performance. Main features: High resolution VGA to 5 megapixel sensor Change resolution to support 5-120 fps Image signal processing Wide dynamic range Intelligent video analysis Low resource occupancy H.264 encoding Flexible video output interface After more than 20 years of development, machine vision technology has gradually become an emerging comprehensive technology, which has been widely used in automotive assisted driving, industrial automation control, image pattern recognition, etc., and has also improved the equipment. The level of automation and intelligence, and the reliability and efficiency of the equipment have been further improved. It is believed that in the near future, machine vision technology will play a greater role in all areas of the national economy. 72V 125Ah Power Battery,Portable Solar Power Station,72V Camping Power Battery,Rv Mobile Energy Storage Power Supply Sichuan Liwang New Energy Technology Co. , https://www.myliwang.com
