Research On High-definition Image Data Real-time Recording System

The rapid development of modern electronic technology has driven the rapid progress of image acquisition and storage technology.As the image clarity and frame rate requirements become higher and higher,the amount of high-definition image data is also increasing,which leads to problems such as high reliability of high-speed transmission of large amounts of data,and difficulty in real-time acquisition and storage of high-definition image data.In view of the above problems,this paper proposes a high-definition image data real-time recording system design.The targeted scheme is designed as follows:(1)Data transmission designFor the problem of high-definition image data transmission,this paper selects HDMI high-definition image data line and USB2.0 protocol data line with relatively mature technology and high adaptability as the transmission channel,and designs high-definition image data interface module and compressed data transmission module.(2)Compression designAiming at the problem that the amount of high-definition image data is large and it is difficult to realize real-time transmission and storage,a compression design scheme based on JPEG2000 image compression standard with FPGA+ADV212 as the core processing chip is proposed.The design scheme is simple to implement and can reduce the amount of high-definition image data.It is easy to carry out subsequent processing.(3)Storage designAiming at the problem that high-definition image data is difficult to realize real-time mass storage,a design scheme is adopted for processing the compressed data stream ping-pong buffer and using a highly stable U disk for storage.The storage device has high modular adaptability and is convenient for data.Instant access and large storage capacity.In this paper,the design principles of the above related targeted problems and solutions are analyzed separately,and the two aspects of the system hardware platform and the software platform are realized.Finally,through a series of experimental analysis,the feasibility of the design scheme and HD are verified.The functional integrity and reliability of the image data real-time recording system have certain practical engineering application value.
