OpenCV / Array应该是CvMat或IplImage /释放捕获对象 [英] OpenCV / Array should be CvMat or IplImage / Releasing a capture object

问题描述

编辑： 数组应该是CvMat或IplImage 不是特定于此问题的错误消息，这是唯一最相关的错误消息。

Edit : Array should be CvMat or IplImage is not an error message specific to this issue, that's the only most relevant error message i got.

我试图使用opencv从一个应用程序中创建一个* .exe。

I'm trying to make an *.exe out of an application using opencv.

我正在使用 Python 2.6 和 openCV 2.1 。

运行的一部分* .exe，我有一个菜单，我可以选择从两个不同的源处理一些图片我的网络摄像头&静态图像。静态图像部分工作，但当我选择网络摄像头这里是输出：

I can run part of the *.exe, i'm having a menu from where i can choose to process some pictures from 2 differents sources my webcam & a static image. The static image part works but when i'm chosing the webcam here is the output:

我的 pyar.py 文件。

使用py2exe构建* .exe给我这个输出：

Building the *.exe with py2exe gave me this output :

The following modules appear to be missing
['ICCProfile', '_imaging_gif', '_scproxy']

我不知道，与我的来源。我试图打包我的应用程序与py2exe& pyinstaller，但输出是一样的。

I don't get it, this is working with my sources. I tried to pack my application with py2exe & pyinstaller, but the output is the same.

我猜* .exe缺少一些东西，但我不知道如何调试它。

I guess the *.exe is missing something but i don't know what neither how to debug it.

推荐答案

这与包装商无关。

问题是我wasn不关闭网络摄像头捕获，我的应用程序的几个进程实际上在后台运行。

The problem was that I wasn't closing the webcam capture, several processes of my app were actually running in the background.

doc 是关于 ReleaseCapture ，但是这个函数显然不是在python绑定，调用：

The doc is talking about ReleaseCapture but this function is apparently not in the python bindings, calling :

del（self.cam）

做得很好， self.cam 是我的 CvCapture 对象。

did the job just well, self.cam being my CvCapture object.
