从相机回调回来，角度一定要传270吗？换成其他的角度，为什么识别不了呢？

@OverRide
public void onPreviewFrame(final byte[] data, final Camera camera) {
synchronized (lock) {
// 处理data
Camera.Size previewSize = camera.getParameters().getPreviewSize();
Plate[] plates = HyperLPR3.getInstance().plateRecognition(data, previewSize.height, previewSize.width, HyperLPR3.CAMERA_ROTATION_270, HyperLPR3.STREAM_YUV_NV21);
for (Plate plate : plates) {
Log.i(TAG, "" + plate.toString());
}

        if (!isStopReg && plates.length > 0) {
            sendPlate(plates);
        }

    }
}
