Screen Size of the camera on the example object detection of tensorflow lite

问题

On the tensorflow lite example object detection, the camera don't take all the screen but just a part.

I tried to find some constant in CameraActivity, CameraConnectionFragment and Size classes but no results.

So I just want a way to put the camera in all the screen or just an explanation.

Thanks you.

I just find the solution, it's in the CameraConnectionFragment class : protected static Size chooseOptimalSize(final Size[] choices, final int width, final int height) { final int minSize = Math.max(Math.min(width, height), MINIMUM_PREVIEW_SIZE); final Size desiredSize = new Size(1280, 720);

protected static Size chooseOptimalSize(final Size[] choices, final int width, final int height) {
final int minSize = Math.max(Math.min(width, height), MINIMUM_PREVIEW_SIZE);
final Size desiredSize = new Size(1280, 720);

// Collect the supported resolutions that are at least as big as the preview Surface
boolean exactSizeFound = false;
final List<Size> bigEnough = new ArrayList<Size>();
final List<Size> tooSmall = new ArrayList<Size>();
for (final Size option : choices) {
  if (option.equals(desiredSize)) {
    // Set the size but don't return yet so that remaining sizes will still be logged.
    exactSizeFound = true;
  }

  if (option.getHeight() >= minSize && option.getWidth() >= minSize) {
    bigEnough.add(option);
  } else {
    tooSmall.add(option);
  }
}

just replace 1280, 720 by what we want.
