可将图像文件直接转换为bin文件,方便烧写,存储。在fpga或者其他开发时,如果想直接把图像存储进flash,可以通过这个工具把图像文件转换成bin文件,很方便

其余图像处理算法的实现,主要在图像处理模块(rgb_gray)进行修改即可。若要查看rtl图,需要在图像生成模块中,引去initial的部分,否则不可综合。

图像采集是数字化图像处理的第一步,开发图像采集平台是视觉系统开发的基础。视觉检测的速度是视觉检测要解决的关键技术之一,也是专用图像处理系统设计所要完成的首要目标“3。传统的图像采集卡只能将采集的图像数据实时传输给计算机,而不能传输给专用图像处理系统,因此需要研制专用的图像采集系统,既能够实时高速获取视觉图像,又能实时将图像数据传输给计算机和专用图像处理系统。   FPGA(FieldProgrammableGateArray)运算速度快,实时性强,易于并行运算和实现流水线结构,编程相对复杂,它实现图像底层处理速度快,易于通过VHDL(VeryHighSpeedIntegrateCircuitHardwareDescripTIonLanguage)语言编写程序实现。以FPGA为底层运算和控制核心,能够通过软件编程无限次更改内部硬件逻辑,改变功能,编程后的FPGA相当于专用集成芯片,采用硬件电路实现软件功能,具有很高的运行速度。典型的视觉应用系统可由下列五个部分组成:图像获取、预处理、特征的提取、分类和识别、响应等5个部分组成,其中预处理、特征提取、分类一识别三个阶段分别对应了视觉任务的底层、中层和高层。视觉检测中图像处理的特点是底层图像处理数据量大,算法简单,占有2/3的计算量,高层图像处理算法复杂,但数据量小。因此,底层图像采集及控制过程由FPGA实现;高层图像处理算法由DSP(DigitalSignalProcessor,数字信号处理)实现。高速完成视觉传感器的数据处理任务。

基于FPGA的嵌入式图像处理系统设计,英文版,非扫描版,内容清晰。 作者简介 Donald G Bailey is Associate Professor in the Institute of Information Sciences and Technology at Massey University, where he leads the Image and Signal Processing Research Group. His research interests include most aspects of image analysis, but in particular the algorithm development process, and training. Bailey has developed a Vision Image Processing System package which has been used in a wide range of image analysis applications. Current and recent projects include: image processing using FPGAs, real time produce grading using machine vision, super-resolution, and sub pixel measurement techniques, camera calibration, and coastal monitoring using automated video analysis. He has been working as an electronics and computer systems engineer in the field of image analysis and machine vision for over 25 years. He began applying FPGA technology to image processing in 2002, and since then has published about 25 papers on issues and applications of FPGAs to image processing. 目录 Preface.
