摘要
随着图像传感器分辨率及数据传输速率的提高,其传输接口由并行DVP接口逐渐转变为MIPI CSI-2接口。然而,目前国内学者较少针对该接口设计图像采集系统。基于此,提出了一套基于MIPI CSI-2接口的图像采集系统的解决方案。该设计采用自主设计的软硬件平台开发,以安森美公司的AR1337 CMOS图像传感器为视频源,采用Xilinx公司的FPGA作为核心处理器,利用其强大的并行处理能力,实现MIPI CSI-2数据接收、协议解析、图像格式转换以及视频输出等操作。经测试,该设计支持的最大视频分辨率为1920×1080,从采集到输出端显示总延时小于100 ms,满足图像采集系统对实时性的需求,为如今越来越广泛的超高清视频应用场景提供了一个完整的解决方案。
With the improvement of image sensor resolution and data transmission rate,its transmission interface has gradually changed from a parallel DVP interface to a MIPI CSI-2 interface.However,at present,domestic university scholars rarely design image acquisition systems based on MIPI CSI-2 interface.Based on this,this paper proposes a set of image acquisition system solutions.This design was developed by an independently designed software and hardware platform,choosing the AR1337 CMOS image sensor made by ON Semiconductor as the video source,regarding FPGA made by Xilinx as the core processor.The system uses FPGA’s powerful parallel processing capabilities to recept MIPI CSI-2 data,analyze MIPI protocol,convert image format,and output video.In the test,the design supports a maximum video resolution of 1920×1080,and the total delay from the acquisition to display is less than 100 ms,which meets the real-time requirements of image acquisition systems.This paper provides a complete solution for more and more widely used ultra high-definition video application scenario.
