在图像上找到一个点(x,y) [英] find a point (x,y) on an image
问题描述
我正在寻找一种方法来检测图像上的点/像素,根据我从用户那里得到的数据。 />
我希望用户扫描物品条形码,并通过它 - 找到图像中的相关项目并标记它(我可以用红点或其他东西来解决)。 。)
例如,如果我在屏幕上显示带有笔,笔记本和订书机的桌面图像,现在用户扫描条形码(一个真正的笔,它会在图像上标记笔。
我想我需要调整我想找到的图像上任何项目的每个项目的x,y然后我问自己我怎么能相对做(如果用户更改屏幕分辨率,例如)
任何想法我该怎么做?
我认为我宁愿使用winform而不是webform,因为该软件假设在特定的计算机中。
谢谢!
我同意ZoltánZörgő的观点。
但是,如果你想深入了解图像识别领域,你需要阅读一些相关主题的文献。我建议你使用计算机视觉和人工智能库AForge.NET:
http:/ /en.wikipedia.org/wiki/AForge.NET [ ^ ],
http://www.aforgenet.com/ [ ^ ]。
我'使用它,它是一个非常强大的东西;它也适用于.NET。
另外,请参阅AForge.NET作者Andrew Kirillov撰写的CodeProject文章(http://www.codeproject.com/Members/Andrew-Kirillov [ ^ ]):

Hi,
I''m looking for a way to detect points/pixels on an image, according to a data I get from the user.
I want the user to scan an item barcode, and by that- to find the relevant item in the image and mark it (I can settle with a red dot or something ..)
for example, if I have on my screen an image of a desk with a pen, a notebook and a stapler and now the user scan the barcode on (a real) pen, it will mark the pen on the image.
I guess I need to adjust the x,y of each item of any item on the image I want to find but then I ask myself how can I do it relatively (if the the user change the screen resolution for example)
Any idea how can I do that?
I think I rather use winform and not webform since the software suppose to be in a specific computers .
thanks!
I agree with Zoltán Zörgő.
However, if you want to dig in the field of image recognition, you need to read some literature on related topics. I would recommend you to use the computer vision and artificial intelligence library AForge.NET:
http://en.wikipedia.org/wiki/AForge.NET[^],
http://www.aforgenet.com/[^].
I''m using it, it''s a very robust thing; and it''s for .NET.
Also, see the CodeProject articles by the AForge.NET author, Andrew Kirillov (http://www.codeproject.com/Members/Andrew-Kirillov[^]):

Good luck,
