问题描述
我下载了一款Android相机2 ，运行良好。
I downloaded an Android camera2 demo, it ran well.
现在我想通过查询。
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
}
}
内在函数应该是一个5元素数组但 intrinsic = characteristics.get（CameraCharacteristics.LENS_INTRINSIC_CALIBRATION）返回null。
The intrinsic is expected to be a 5-element array but intrinsic = characteristics.get(CameraCharacteristics.LENS_INTRINSIC_CALIBRATION) returns null.
推荐答案
只有在相机设备支持。
The lens intrinsics are only guaranteed to be defined if the camera device supports the DEPTH_OUTPUT capability.
截至目前，camera2 API的深度扩展是新的，基本上任何Android设备都不支持。
As of right now, the depth extensions to the camera2 API are new, and not yet supported by basically any Android device.
