无法使EMGU.CV中的SURF示例正常工作？ [英] Cannot get SURF example in EMGU.CV to work?

问题描述

我正在尝试检测两个图像中显示的图案。因此，我一直试图使用在emgu.CV中找到的SURF算法，但是给出的 SURFFeature示例给了我以下错误：

  Emgu.CV.dll中发生了类型为'Emgu.CV.Util.CvException'的未处理异常
 
其他信息：OpenCV：规范== NORM_L1 ||规范== NORM_L2 ||规范== NORM_HAMMING 
  

有什么办法解决此问题吗？

当我尝试 Hello World示例和面部检测示例时，两者似乎都可以正常工作。

感谢您的建议！

武器。

解决方案

显然，构建被搞砸了。

啊哈， 找到了。这里的错误是在Emgu.Cv.Gpu / GpuBruteForceMatcher.cs第22和27行中。

第22行当前显示为：
L2Dist，

它应该显示为：L2Dist = 4，

第27行当前显示为：HammingDist

它应该显示为：HammingDist = 6

使用这些更改重建Emgu.CV.Gpu dll，并且可以正常工作。 / p>

I am trying to detect a pattern shown in two images. Hence I have been trying to use the SURF algorithim found in emgu.CV, but the "SURFFeature" example that is given gives me the following error:

    An unhandled exception of type 'Emgu.CV.Util.CvException' occurred in Emgu.CV.dll

Additional information: OpenCV: norm == NORM_L1 || norm == NORM_L2 || norm == NORM_HAMMING

Any ideas how to fix this?

When I try the "Hello World" example and the face detection example, both seem to work fine.

Thanks for any advice!

Fouad.

解决方案

Apparently the build was messed up.

http://www.emgu.com/bugs/show_bug.cgi?format=multiple&id=74

Aha, found it. The error here is in Emgu.Cv.Gpu/GpuBruteForceMatcher.cs lines 22 and 27.

Line 22 currently reads: L2Dist,

It should read: L2Dist = 4,

Line 27 currently reads: HammingDist

It should read: HammingDist = 6

Rebuild the Emgu.CV.Gpu dll with those changes and it works.
