ov5640 驱动调试

hudei21 2012-11-23 01:30:35

最近搞摄像头，移植，调试信息如下，大虾帮看看错在哪里，整了2周，没有出来。我是摸不到头绪了。

OV5640摄像头调试简单步骤

用verilog编写的OV5640摄像头DVP接口寄存器驱动程序，经过调试的，可以直接拷贝。已在Xilinx Spartan6 FPGA调试验证。

本课程讲解sensor直接采集的图像都有各种不理想性，因此在编码前都会经过一个软件方式处理，这个处理就叫ISP，图像的IQ调试就是研究这些处理算法和实现的。常见的IQ调试技术如：线性纠正、噪声去除、黑电平校正、坏点去除、颜色插补、Gamma 校正、RGB2YUV 转换、主动白平衡处理、主动曝光控制、AE评估等。随着通信行业发展，网速越来越快，网络也从文本时代发展越过语音时代到了现在视频时代，“优酷、爱奇艺”、“微视频”、“直播”等的出现也是视频逐步成为主流媒体的证据和表现。航拍、视频监控、刷脸过关检测、汽车ADAS系统等应用也是视频在主流行业中的应用，因此视频的采集、编解码、传输、识别等技术变得越来越有价值，涌现出了“海康威视”、“大华股份”、“深圳英飞拓”等一批明星企业，名扬海内外，动辄市值几百亿。同时在芯片级，国产华为海思HI35xx系列视频编解码方案也逐步取代进口芯片（如TI、安霸）成为主流方案。视频行业技术含量高、难度大、学习周期长、发展变化快而资料少，因此行业比较缺人、工资较高。如海康威视，普通高校硕士研究生应届进入年薪普遍高于15-20万，在嵌入式linux领域也算高工资技术方向了。本项目是朱老师及其团队推出的一个嵌入式linux领域重量级企业级实战项目，选用华为海思HI3518E方案，结合OV9712/AR0130 Sensor实现图像采集和H.264编码压缩，并通过ethernet和WIFI，以socket实时流和RTSP等方式，实现720P/960P高清视频传输。本项目共分11季，从海思SDK开发环境搭建，到sample程序讲解、SDK中API函数解析，到H.264编解码、RTSP流媒体传输、MP4文件打包，到图像IQ调试、图像识别等视频领域高阶内容，可以说从零基础入手，对图像采集、编解码、网络传输、图像存储和识别做了全方位的详细讲解和代码分析，是目前市面上**一套系统讲解图像和视频技术的视频课程。
