想要pcie视频采集卡只将屏幕截图放入内存中 [英] want pcie video capture card put only screenshot image in memory

问题描述

你好







我想做模式识别。

有没有办法在不知道驱动程序的情况下与pcie驱动程序通信？

我必须向pcie卡制造商索取信息？





如何做到这一点？ ：

.....



mem1 = malloc（xx）;

getpattern（mem1）; //将特殊图像模式的数据库放入mem1



mem2 = malloc（xx）;

getpicture（mem2）; //获取pcie视频采集卡的截图并输入mem2



patternrecognition（）; //在模式和截图之间进行图像比较



......

对我有什么建议吗？

Hello



I want to do pattern recognition.
Is there a way to communicate with pcie driver without knowledge of the driver ?
I have to beg for information to the pcie card manufacturer ?


How to do this ? :
.....

mem1 = malloc(xx);
getpattern(mem1); // put database of special image pattern in mem1

mem2 = malloc(xx);
getpicture(mem2); // get screenshot of pcie video capture card and put in mem2

patternrecognition(); // do image compare between pattern and screenshot

......
Have you any advice for me ?

推荐答案

好吧，它有点难以知道什么制造/型号的pcie卡 - 通常你不必去乞求信息，它应该在制造商的SDK中，通常隐藏在他们网站上的支持下，如果它是一个受欢迎的品牌/型号，即使是所有知识字体的谷歌应该有一些点击



确定制作/型号，在这里更新这些信息，有人可能能指出你正确的方向



我只是使用[c ++ pcie视频捕捉进行了快速搜索这些卡片有很多点击，所有人都说他们有一个c ++兼容的SDK

Well, its a bit hard not knowing what make/model pcie card - usually you wouldn't have to go begging for the info, it should be in an SDK from the manufacturer, usually hidden under 'support' on their site, and if its a popular make/model even the font-of-all-knowledge Google should have some hits

Determine the make/model, update that info here, and someone may be able to point you in the right direction

I just did a quick search using [c++ pcie video capture interface] and had lots of hits for such cards, all saying they had a c++ compatible SDK

通常你不直接处理显示卡驱动程序，而是使用库（例如 GDI 或 GDI + 在 Windo ws ，请参阅：在GDI +中使用LockBits [< a href =http://supercomputingblog.com/graphics/using-lockbits-in-gdi/target =_ blanktitle =New Window> ^ ]）。其他平台也提供用于访问图像数据的库。

Usually you don't deal directly with the display card driver, instead you use a library (like for instance GDI or GDI+ on Windows, see for instance: "Using LockBits in GDI+"[^]). Other platforms provide libraries for accessing image data as well.
