至於如何在專案中如何新增OpenCv的SDK在此不再贅述：我引入的OpenCv-SDK版本為OpenCV-3.1.0-android-sdk

在Activity中實現CameraBridgeViewBase.CvCameraViewListener2介面並重寫其方法,在

Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame)方法中可以使用OpenCv的儲存圖片的方法，如下：

Imgcodecs.imwrite("/storage/emulated/0/" + "OpenCvimwrite.jpg", inputFrame.rgba());
 

    int size = mFrameWidth * mFrameHeight;
    size  = size * ImageFormat.getBitsPerPixel(params.getPreviewFormat()) / 8;

    size = size * ImageFormat.getBitsPerPixel(params.getPreviewFormat());
 

public void tackPhoto(final String name) {
        if (mCamera != null) {
            mCamera.takePicture(null, null, new Camera.PictureCallback() {
                @Override
                public void onPictureTaken(byte[] data, Camera camera) {
                    Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
                    saveMyBitmap(bmp, name);
                }
            });
        }
 

 public void saveMyBitmap(Bitmap mBitmap, String photoName) {
        if (isMediaMounted()) {
            String SDCardPath = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
            createFileDir(SDCardPath + File.separator + "OpenCv");
            String FilePath = SDCardPath + File.separator + "OpenCv" + File.separator + photoName + ".jpg";
            File file = new File(FilePath);
//        "/storage/emulated/0/OpenCv" + "OpenCv.jpg",
            BufferedOutputStream bos = null;
            try {
                FileOutputStream fos = new FileOutputStream(file);
                bos = new BufferedOutputStream(fos);
                mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
                bos.flush();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                try {
                    if (mBitmap != null) {
                        mBitmap.recycle();
                    }
                    bos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        } else {
            Log.e(TAG, "saveMyBitmap: 沒有掛載記憶體卡，無法儲存圖片");
        }
    }
