android - 相机应用的全景解决方案

Question

相机应用程序有panorama开源解决方案吗？Android我遇到了这些选项：

1. 全景gl-android

2. WideAnglePanoramaModule.java

但是他们看起来有点老，没有支持，有什么更新的吗？

我也遇到了这个页面：

但是我找不到太多关于它的文档。

我想获得一个完整的解决方案，包括捕获图像、拼接和显示。

Answer 1

看看这篇文章：

我不喜欢的是所有图像都来自资产。我用来自firebase的图像做到了：

添加依赖：

  dependencies {
  /*
  * Google VR SDK
  * Release version: https://github.com/googlevr/gvr-android-sdk/releases
  * */
  implementation 'com.google.vr:sdk-panowidget:1.180.0'
  implementation 'com.github.silvestrpredko:dot-progress-bar:1.1'
  }

添加类

public class SimpleVrPanoramaActivity extends Activity {

@BindView(R.id.progressBar2)
DotProgressBar dotProgressBar;

@BindView(R.id.pano_view)
VrPanoramaView panoWidgetView;

private String bar_panorama1;
private String mPost_key = null;
private Bitmap[] bitmaps = new Bitmap[1];
private DatabaseReference databaseReference;
private VrPanoramaView.Options panoOptions = new VrPanoramaView.Options();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_panorama);

    ButterKnife.bind(this);


    if (getIntent().getExtras() != null) {
        mPost_key = getIntent().getExtras().getString("bar_id");
    }

    panoOptions.inputType = VrPanoramaView.Options.TYPE_MONO;

    databaseReference = FirebaseDatabase.getInstance().getReference().child("bars").child(mPost_key).child("pano");

    fetchPanorama();
}

private void fetchPanorama() {

    databaseReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

            bar_panorama1 = dataSnapshot.child("i1").getValue(String.class);

            glideImage(bar_panorama1);
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

            Toast.makeText(SimpleVrPanoramaActivity.this, "Проверьте подключение к интернету!", Toast.LENGTH_LONG).show();
        }
    });
}

public void glideImage(String bar_panorama) {

    Glide.with(SimpleVrPanoramaActivity.this)
            .asBitmap()
            .load(bar_panorama)
            .into(new CustomTarget<Bitmap>() {
                @Override
                public void onLoadFailed(@Nullable Drawable errorDrawable) {

                    dotProgressBar.setVisibility(View.GONE);
                }

                @Override
                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {

                    bitmaps[0] = resource;

                    panoWidgetView.loadImageFromBitmap(bitmaps[0], panoOptions);

                    dotProgressBar.setVisibility(View.GONE);
                }

                @Override
                public void onLoadCleared(@Nullable Drawable placeholder) {
                }
            });
}

@Override
protected void onPause() {
    panoWidgetView.pauseRendering();
    super.onPause();
}

@Override
protected void onResume() {
    super.onResume();
    panoWidgetView.resumeRendering();
}

@Override
protected void onDestroy() {
    // Destroy the widget and free memory.
    panoWidgetView.shutdown();

    super.onDestroy();
}


}
