基于Camera Link接口的CMOS相机小型化设计

Miniaturization Design of CMOS Camera based on Camera Link Interface

基于Camera Link接口设计了一款小型CMOS相机并进行仿真验证。硬件的小型化设计包括硬件功能模块划分、主要器件选型、整机供电分布以及PCB设计等;软件的小型化设计为以FPGA内部集成Camera Link并串转换模块来代替传统的转换芯片。整机实测结果表明相机工作稳定可靠。本研究对于CMOS相机小型化设计具有借鉴意义,同时由于探测器模块配置的灵活性,亦可作为CMOS相机的一种通用处理平台。

With the release and implementation of the"Made in China 2025"strategy,the manufacturing industry has put forward higher and higher requirements for automated product production.This article designs a small CMOS camera based on the Camera Link interface and introduces it from both software and hardware.The miniaturization design of the hardware includes the division of hardware functional modules,the selection of main components,the distribution of the power supply of the camera,and the PCB design.The miniaturization of the software is designed to integrate the Camera Link parallel-serial conversion module inside the FPGA to replace the traditional hardware conversion chip and perform simulation verification.Experimental results show that the camera is reliable and stable.It has reference significance for the miniaturization design of CMOS camera.Due to the flexibility of the configuration of the detector module,the camera can be used as a general processing platform for CMOS cameras.
