tensorflow lite的示例对象检测中相机的屏幕尺寸 [英] Screen Size of the camera on the example object detection of tensorflow lite

问题描述

在tensorflow lite示例对象检测中，摄像头并不能完全占据整个屏幕，而只是整个屏幕。

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

我试图在CameraActivity中找到一些常量，CameraConnectionFragment和大小类，但没有结果。

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

所以我只想一种将照相机放在所有屏幕上的方法，或者只是一种解释。

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

谢谢。

推荐答案

我刚刚找到了解决方案，它在CameraConnectionFragment类中：
受保护的静态大小choiceOptimalSize（final Size []选择，最终int宽度，最终int高度）{
final int minSize = Math.max（Math.min（width，height），MINIMUM_PREVIEW_SIZE）;
最终大小期望的大小=新的大小（1280，720）;

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);
  }
}

只需将1280，720替换为我们想要的。

just replace 1280, 720 by what we want.
