Java-Android camera2镜头固有校准

我下载了一个Android camera2 demo,它运行良好.

现在,我想通过查询CameraCharacteristics获得摄像机的固有矩阵.

我的代码是

private void setUpCameraOutputs(int width, int height) {
    Activity activity = getActivity();
    CameraManager manager = (CameraManager) activity.getSystemService(Context.CAMERA_SERVICE);
    try {
        for (String cameraId : manager.getCameraIdList()) {
            CameraCharacteristics characteristics
                    = manager.getCameraCharacteristics(cameraId);
            float[] intrinsic = new float[5];
            intrinsic = characteristics.get(CameraCharacteristics.LENS_INTRINSIC_CALIBRATION);
    //...... leave out the following part
        }
    }

内在函数应为5元素数组,但内在= Characteristics.get(CameraCharacteristics.LENS_INTRINSIC_CALIBRATION)返回null.

解决方法:

只有在摄像头设备支持DEPTH_OUTPUT capability的情况下,才能保证定义镜头的固有特性.

截至目前,camera2 API的深度扩展是新的,并且基本上不受任何Android设备支持.
