How to catch native OpenCV’s errors code (CVException handling)

In order to display the native opencv’s error code, please enclose the code in Utils.setDebugMode(true) and Utils.setDebugMode(false). Example Code: // // CVException handling example // // 32F, channels=1, 3×3 Mat m1 = new Mat (3, 3, CvType.CV_32FC1); m1.put (0, 0, 1.0f, 2.0f, 3.0f, 4.0f, 5.0f, 6.0f, 7.0f, 8.0f, 9.0f); // 8U, channels=1, 3×3 Mat m2 = new Mat (3, 3, CvType.CV_8UC1); m2.put (0, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9); // dump Debug.Log (“”m1=”” + m1); Debug.Log (“”m1.dump()=”” + m1.dump ()); Debug.Log (“”m2=”” + m2); Debug.Log (“”m2.dump()=”” + m2.dump ()); #if UNITY_STANDALONE || UNITY_EDITOR // Publish CVException to Debug.LogError. Utils.setDebugMode (true, false); Mat m3 = m1 / m2; Utils.setDebugMode (false); // Throw CVException. Utils.setDebugMode (true, true); try { Mat m4 = m1 / m2; } catch (Exception e) { Debug.Log (“”CVException: “” + e); } Utils.setDebugMode (false); #else Debug.Log (“”The setDebugMode method is only supported on WIN, MAC and LINUX.””); #endif Execution Result: m1=Mat [ 3*3*CV_32FC1, isCont=True, isSubmat=False, nativeObj=0x820637680, dataAddr=0x820295296 ] m1.dump()=[1, 2, 3; 4, 5, 6; 7, 8, 9] m2=Mat [ 3*3*CV_8UC1, isCont=True, isSubmat=False, nativeObj=0x820637792, dataAddr=0x820619712 ] m2.dump()=[ 1, 2, 3; 4, 5, 6; 7, 8, 9] core::divide_12() : OpenCV(3.4.1-dev) C:\Users\xxxxx\Desktop\opencv\modules\core\src\arithm.cpp:683: error: (-5) When the input arrays in add/subtract/multiply/divide functions have different types, the output array type must be explicitly specified in function cv::arithm_op m3=Mat [ […]
