Contributing to Mapillary with GoPro Hero 11

Latest Desktop Uploader support video formats including CAMM file and .mp4 files. @filipc

It’s not expected to have make model is “none none”. I’ll let @tao know on this issue and he can fix it shortly.

This is a known issue. We will fix it soon.

@filipc I see the image quality differs in these two sequences. How did you capture and upload them?

  2. Mapillary

1 is timelapse on a bicycle with the sun behind
2 is video in a car with a partially clouded sky

I think timelapse is best unless my jagged sequence on bicycle remains.

Captures in timelapse mode AFAIK will be saved as a video (.mp4). Did you convert these videos to images with any external tool before uploading with Desktop Uploader?

Can be saved either as individual photos in Timelapse Photo mode, or as a video in Timelapse Video mode. Mapillary recommends to use the Timelapse Photo mode with a 0.5s interval, which I think @filipc did.

@tao I suspect #2 was filmed with either the Narrow or Linear lens mode. The way GoPro does this is by cropping the sensor and upscaling it back to 5.3k. In other words, when in Wide, Linear or Narrow lens modes, the output video is not the same 5.3k the sensor sees, but worse quality.

  1. It gave immediately jpg in my Gopro.

I use linear in my car unless I forget.
The last time I forgot it seemed not so bad. There was only too much dashboard and maybe more image on the sides.

I have tested the three modes with the Max lens.
Before the results are available, I can already say that the uploader log does not show the jpg files.

Edit : the MP4 files do not appear in the ingesting list.
The upload happened so quickly that I think that nothing has happened.

So with the Max Lens I can have a horizontal FOV of 139 degrees.

I shot sequences of 4 photos in an angle of 90 degrees.
I hoped for a enough overlap for a full circle. But usually this does not happen.

Max Photo
Lens Max Superview 16 mm
I suppose that Hypersmooth is off in Photo mode.

Now I am not sure what to try next.
Timelapse or video ? What about the motion blur ?
Is Hypersmooth the same as Horizontal leveling ?
The user interface is not clear to me.

I think that video and other modes do not go together in the uploader.

Max lens
Max time warp
2.7 K Speed 2x SV Horizon leveling off

This gives MP4 files.
Next time I will try 5x speed, because there are just not enough pictures.

I guess, if you increase speed in time warp you will get less pictures

Max video 2.7 K 25 SV on foot

Max video 2.7 K 25 SV on bicycle

139 -113 = 26 degrees difference, but less pictures

The max lens does not do wonders, except for single shots.
It is amazing how much I can get in one picture.

The wide angle is also handy for mapping.
I can see the two corners, the roof, the zebra crossing in one picture.

There are no more excuses for getting it wrong.

Looks fine to me. Mapillary just needs to add HERO11’s lens parameters to the viewer so that things look straight. It’s awful to look at bent pictures. :crazy_face: Nevertheless, I would always prefer a linear lens on the camera over any digital re-projection.
