设计的多视频接口紫外成像系统,支持通过USB3.0接口输出图像数据至PC上进行显示,并且创造性地提出通过MIPI CSI-2接口将图像数据输出至Hi3519处理器进行显示,同时提出了两种类型的接口转换方法。设计了成像系统的图像采集模块、通过现场可编程门阵列(FPGA)以硬件描述语言(Verilog)构建的图像处理模块、I2C通信模块以及接口桥接转换模块等,其中图像处理模块作为系统的主控核心模块,分别控制图像采集模块完成了图像信息的采集、控制I2C通信模块和接口桥接模块完成开发平台的实时显示,另外该系统针对平滑噪声的处理集成了双边滤波算法、并且设计了图像模式切换、HDR模式切换、图像缩放和图像翻转等多种功能。通过对系统进行测试和验证,结果系统能够稳定提供分辨率为2 048×2 040@44 fps的视频流,结果表明该系统且具备低功耗的优势,最终完成了紫外成像系统和专业领域应用的精准匹配。
The designed multi-video interface ultraviolet imaging system supports the output of image data to the PC for display through the USB3.0 interface, and creatively proposes to output the image data to the Hi3519 processor for display through the MIPI CSI-2 interface, and proposes two type of interface conversion method. Designed the image acquisition module of the imaging system, the image processing module constructed by the field programmable gate array(FPGA) and the hardware description language(Verilog), the I2C communication module and the interface bridge conversion module, among which the image processing module is the main control of the system. The core module controls the image acquisition module to complete the acquisition of image information, controls the I2C communication module and the interface bridge module to complete the real-time display of the development platform, and the system integrates bilateral filtering algorithms for smooth noise processing, and designs image mode switching, HDR mode switching, image zoom and image flip and other modes. Through engineering testing and verification of the system, the system can stably provide a video stream with a resolution of 2 048×2 040@44 fps. The results show that the system has the advantage of low power consumption, and finally completes the precise matching of ultraviolet imaging system and applications in professional fields.
