Why is it showed as a 360 pic?

the original file/exif would help - something is messed up there I’d reckon, probably on Huawei’s camera software part

I recently uploaded 360 images where I later descovered they missed the proper EXIF tags to be “official 360” images. But Mapillary did detect them as 360 images.

I can’t speak for Mapillary naturally, but I think this part of your EXIF/image data may clarify things:

The width is exactly double of the height. That is a tell tale property of a 360 image. And I think there are rarely “normal” images with that aspect ratio (2:1). So maybe Mapillary assumes a 360 image solely on that aspect ratio?

Yep, looks like this is indeed the reason.

So that do you/Mapillary want me to do :slight_smile: ?

Equirectangular pictures are interpreted by some software as 360 images whether they are or not. Is there any way you can change the aspect ratio to something other than 2:1?

11

Shave one pixel of the width, or height and up,oad again… I think that’ll work!

I was looking for a discussion about a complete opposite of the described bug, i.e. in my case the 360 sequence renders as a flat image (see Mapillary), but could not find any. Looking at the OP, the bug is still there, so should I just delete the sequence and try to re-submit it to get a 360 rendering?

Also, for whatever reason, all of my 360 sequences display only the first (out of about 500) shots…

Sounds like a bug - since I set the exif info on my video extract stills to get them into 360° stills

Full Pano Height Pixels         : 2880
Full Pano Width Pixels          : 5760
Use Panorama Viewer             : True

Or my full script is this :

exiftool -geotag ${gpxfiles} -ProjectionType="equirectangular" -UsePanoramaViewer="True" -"PoseHeadingDegrees<exif:GPSImgDirection" -"CroppedAreaImageWidthPixels<ImageWidth" -"CroppedAreaImageHeightPixels<ImageHeight" -"FullPanoWidthPixels<ImageWidth" -"FullPanoHeightPixels<ImageHeight" -CroppedAreaLeftPixels="0" -CroppedAreaTopPixels="0" ./
