我使用的Java OpenCV的，我尝试加载一张照片，在它运行的模板匹配。 模板匹配方法处理垫的对象，所以我需要加载图像，并将其转换成垫。

I am using Java openCV, and i try to load a photo and run the template matching over it. The template matching method deals with Mat objects, so i need to load the images and convert them into Mat.

我的方式做到这一点是：

The way i do it is:

Bitmap i = BitmapFactory.decodeFile("/sdcard/TVguide/Detection/detected.jpg");
image = Utils.bitmapToMat(i);

这样我加载从我的Andr​​oid SD卡中的照片，并试图将其转换成使用OpenCV的方法bitmapToMat垫目标。 的问题是，在转换时，应用程序崩溃。

This way i load a photo from my android SD card, and try to convert it into Mat object using the openCV method bitmapToMat. The problem is that on the conversion, the application crashes.

下面是LogCat中：

我不明白，如果我做错了什么，或者它仅仅是一个越野车的OpenCV。

I can't understand if i am doing something wrong or it is just a buggy openCV.

谢谢 的Eyal

推荐答案

您需要将您的位​​图转换为RGBA格式为：

You need to convert your bitmap to the RGBA format:

Bitmap bmp32 = i.copy(Bitmap.Config.ARGB_8888, true);

其实这是对Android的OpenCV的用户群讨论最多的问题： https：//开头groups.google.com/group/android-opencv/

有关此问题的解决方法是在OpenCV的树干已经上市，并会被列入到的OpenCV的下一个版本。

The fix for this problem is already available in OpenCV trunk and will be included into the next release of OpenCV.

您也可以使用OpenCV的API读取图像：

Also you can read image using the OpenCV API:

Mat image = Highgui.imread("/sdcard/TVguide/Detection/detected.jpg");
