【摘要】：自动成像协会(Automated Imaging Association,AIA)在2013年初发布了用于高速图像数据传输的USB3 Vision标准。首先简要介绍了基于该标准的EMCCD相机高速数据传输系统的设计方案,重点介绍了传输系统的构建和图像采集软件的设计。其中,传输系统的构建主要是在QUARTUS II的开发环境下,移植EMCCD相机数字控制器,使用VHDL语言编程设计一个控制器,产生USB3.0芯片USB3014的读写时序以及相关的逻辑信号,并且完成模拟图像产生和针对USB3 Vision标准的数据传输格式转换的功能;图像采集软件的编写是在VS2010开发环境下利用CYPRESS公司提供的应用程序接口(API),采用C++语言实现。最后进行了模拟图像的采集实验,并且进行了误码率估算。
[Abstract]:Automated Imaging Association (AIA) released the USB3 Vision standard for high-speed image data transmission in early 2013. Firstly, the design scheme of EMCCD camera high-speed data transmission system based on this standard is briefly introduced, with emphasis on the construction of transmission system and the design of image acquisition software. Among them, the construction of transmission system is mainly in the development environment of QUARTUS II, transplant EMCCD camera digital controller, use VHDL language programming to design a controller, and generate the reading and writing timing and related logic signal of USB3.0 chip USB3014. And the function of generating analog image and converting data format according to USB3 Vision standard is completed. The software of image acquisition is realized by C language under the environment of VS2010 development using the application program interface provided by CYPRESS company. Finally, the acquisition experiment of simulated image is carried out, and the bit error rate is estimated.
