    String imgPath = "res/image/test_image/plate_judge.jpg";
    opencv_imgcodecs opencv_imgcodecs = null;
    opencv_core.Mat src = opencv_imgcodecs.imread(imgPath);
    String ret=plateRecognise(src); //得到结果 System.err.println(ret);
    System.out.println(ret);

输出的是
川A0CP56
而实际应为
苏A0CP56
如下：

不知这是什么情况。

有没有解决方案

跑res下面的测试图没问题

一旦切换到自己的图片就报错：

OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cv::cvtColor, file C:\projects\bytedeco\javacpp-presets\opencv\cppbuild\windows-x86_64\opencv-3.1.0\modules\imgproc\src\color.cpp, line 8000

一开始以为是图片问题 我还特意拿了手机去楼下拍摄了

结果发现不是那么回事 就是程序无法使用

在安卓上面怎么使用？我安卓里面用的 org.opencv.core.Mat.Mat() 创建的 Mat ，但是调用你的函数就不行，你的函数用的是 opencv_core.Mat ，两个不知道怎么转换
