问题描述
在阅读 RAW图像格式的维基百科页面这是任何图像的数字负片。
要查看或打印,从相机图像传感器的输出具有
进行处理,即,转换成的照相渲染
场景,然后存储在一个标准光栅图形格式如
JPEG。该处理中,是否进行在相机或稍后在一个原始文件
转换器,涉及多项业务,通常包括
块引用>我有些.RAW文件从我的罗技C920使用 V4L2例如抓起但是当我展示它看起来像这样的形象:
RAW图像,其中在其它帧我可以看到我的影子有谁知道如何处理这样的文件,查看完整的帧?
解决方案的ffmpeg -f -s rawvideo 640×480 -pix_fmt yuyv422 -i帧1.raw帧1.JPG
选项分别设置根据
V4L2
code相连,且产生的图像是你所期望得到的。After reading Wikipedia page of Raw image format which is the digital negative of any image.
To be viewed or printed, the output from a camera's image sensor has to be processed, that is, converted to a photographic rendering of the scene, and then stored in a standard raster graphics format such as JPEG.

I have some .raw files grabbed from my Logitech c920 using v4l2 example but when I display the image it looks like this: a raw image where in other frames I can see my shadow
Does anyone knows how to process such files to see the complete frame ?
Here is a link to the original .raw file
解决方案ffmpeg -f rawvideo -s 640x480 -pix_fmt yuyv422 -i frame-1.raw frame-1.jpg
The options were set based on the
v4l2
code linked, and the resulting image is the one you would expect to get.这篇关于使用的ffmpeg或OpenCV的处理.RAW图像的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
