The Design Of Multi-channel Image Acquisition And Processing Platform Based On ZYNQ

Image acquisition and processing systems have been widely used in industrial production,medical,aviation,military and other fields with the development of electronic technology.In these fields,the requirements for real-time,portability,stability,and expandable flexibility of the overall system for image acquisition and processing are increasingly high.In response to these new requirements,this paper specifically designs a ZYNQ-based system that meets these requirements: Multi-channel image processing platform design solutions.This paper describes in detail the difficulties that need to be solved in the design of the platform.This design makes full use of the FPGA's parallel processing capabilities and its advantages in image processing,as well as ARM's flexible configuration,which enables the system design to have excellent scalability,excellent performance,and good real-time performance.The internal of the board mainly completes the functions of digital image transmission,preprocessing and storage,and is designed to be composed of hardware logic and software control.The FPGA logic part mainly completes the functions of transmission and image preprocessing.For this reason,IIC bus control state transition algorithm,image decoding algorithm and coding algorithm,data matching algorithm,image memory data read-write module and hardware accelerated image preprocessing algorithm are designed.The key part of the software is to design and implement the driving algorithm for some IP cores in the logic part of the FPGA,and complete the relevant configuration according to the requirements of some projects such as power-on self-start.The design of this thesis can be used for rapid development and debugging of the entire project,and the use of unique logic analyzers to detect internal signals to quickly find and solve problems.By downloading and debugging the project and the program for the test prototype,this paper implements a design scheme for a multi-channel image acquisition and processing platform based on ZYNQ.The real-time performance of image transmission and processing is stabilized by using the ZYNQ chip.The design of this paper has a very high practical application value,and can be extended design for further research.
