How do I rotate the live object detection screen on Temi Robot?

Asked 2021-Jul-02 at 07:51

I am currently using android-demo-app/ObjectDetection/ On Temi Robot, the preloaded images are working so far but when I press "live" to go to live object detection screen, it is rotated 90 degrees to the right.

Temi robot only have a front facing camera on the same side of the screen.

I have tried changing textureView.setTransform() imageAnalysisConfig.Builder().setTargetRotation() imageAnalysis.setTargetRotation() but to no avail

Also tried changing AndroidManifest.xml screenOrientation under activity tag to fullSenor or Landscape but nothing changed.

I have been looking up and down on the Android Developer CameraX page for an answer first link second link but I can't find any. Maybe I am not smart enough to find the solution here.

Any help is much appreciated!

QUESTION

Mapbox in Android - Black color around GEOTiff raster layers

Asked 2020-May-28 at 14:11

Goal

I need to add some aeronautical layers taken from FAA to the map. The layers are provided as GeoTIFF files.

Steps

Downloaded a GeoTiff file from FAA website.
Using QGis app clipped the legend from the file. Actually the issue occurs without this step as well.
Reprojected it to EPSG:3857 using GDAL command gdalwarp -q -t_srs EPSG:3857 -dstalpha -of vrt Albuquerque\ SEC\ 104-cut.tif /vsistdout/ | gdal_translate -co compress=lzw /vsistdin/ Albuquerque\ SEC\ 104-north-up-cut.tif. Otherwise I got Error creating Mapnik Datasource: Invalid raster: Invalid rotation value in geotransform array when uploading to Mapbox.
Created a Tileset by uploading GeoTIFFs to Mapbox.
Created a new style in the Mapbox Studio.
Added the tilesets as layers.

Mapbox Studio Result

The map is showing well in Mapbox Studio:

Android Result

However in Android app this style shows with some black borders of random width depending on zoom level and camera position. Here is how it looks in android:

I tried it on Pixel 3a (Android 10), Nexus 5x (Android 8.1) and Android emulator (Android 10). I have good internet connection and gave it enough time so the tiles are loaded.

The source code where the map is embedded is official Demo app. I just replaced token and style URL:

The black borders should be transparent, but the raster image format Mapbox is using (JPG) does not support transparency, which is a known issue that exists in every gl-native-based SDK. This issue presents itself when you reference a style that has the raster layer built in.

As a workaround, you can follow Mapbox's troubleshooting guide on troubleshooting raster images with black backgrounds to make your tileset transparent and then add the tileset as a RasterSource within your Android application to display the raster tile as expected.

Please take a look at the following example as a reference for adding a RasterSource:

Add a WMS Source

Instead of calling the rasterSource using "mapbox://username.tilesetID", you need to call it similarly to the Add a WMS Source example. The code below will resolve your issue:

style.addSource(RasterSource( "albuquerque-source", TileSet( "tileset", "https://api.mapbox.com/v4//{z}/{x}/{y}.png?access_token=" ), 256 ))

How do I serialize an NLP classification PyTorch model

I worked out how to do this after a while. The issue was that the Fastai model wasn't tracing correctly no matter what shape of input I was using.

In the end, I used another text classification model and got it to work. I wrote a tutorial about how I did it, in case it can help anyone else.

NLP PyTorch Tracing Tutorial

Begin by opening a new Jupyter Python Notebook using your preferred cloud machine provider (I use Paperspace).

Next, copy and run the code in the PyTorch Text Classification tutorial. But replace the line…
