Just bought a Garmin XE Virb and a GoPro suction cup. Looking for some guidance. The only mount place that did not capture part of the car was on the front of the hood. That is kind of low, and captures a lot of road.
I had been hoping to put it on the car roof to get shots from a bit higher up. But then I got parts of the car in the pictures.
If you mount the camera on the roof, you need to aim the camera a bit upwards until you don’t see the car anymore.
An alternitive could be to take pictures backwards
@Andblu I have the same setup and am happy to help. I put mine on the front of the hood as well. This tends to get a lower angle view, but it isn’t that bad. The wide angle Virb lense doesn’t have any trouble getting the entire scene.
Here’s an example of the front of the hood mount. Map location.
Update from my earlier post with the GoPro. I’m now using two Garmin Virb XEs. These are great cameras, good for much more than Mapillary. I still rely on the GoPro suction cups because they’re the best ones out there, in my experience. I don’t use the tether anymore though, as the charging cable acts as a bit of a tether. I suppose this is risky, but I’ve never had an issue. I’ve seen videos where this suction cup is stuck to the side of a rocket, so I think it will stay stuck.
Here are some photos of the Garmin Virb XE on the front, and then on the side of the vehicle. The front of the hood works best for the front view, and the side window is great for side view.
Hi @talllguy, I was just wandering how you make sure that the orientation or compass direction (what is the correct term here?) is saved to the images and interpreted correctly by Mapillary?
I record with my gopro and was wandering if this is something that needs to be set/written to the files prior to upload.
@seb The image direction (technically the gpsImgDirection tag in the image’s metadata) is what we’re talking about.
When you record with GoPro, the photos don’t have any GPS information, so you’ll have to enjoin that information using a tool or script. Which are you using?
The best way I’ve found to update the gpsImgDirection tag is to use Mapillary’s interpolate_direction.py script. Find it here with instructions on usage. With this script, you can specify the angle of an image to apply an offset, e.g. 90 degrees to the right. That is how I keep ensure the orientation / compass direction is correct.
I read a post in the following threat Anyone from Australia? where @tastrax wrote, he used an aerial mount. No idea what that is, but googling let me to this site with mounts for antennas. Looks really interesting and could be worthwhile to see if something could work with a rammount for exemple
I initially had a RAM 25mm ball and a small arm attached but it wobbled around too much for my liking. I now have a old mount from the top of a tripod that is much better. Lower to the car and not as much flex.
I actually like the look of this one because its adjustable
My fixed mount I needed to get just right for the correct field of view. Not easy but I managed by sliding washers under the mount to ‘rake it upwards’
I made myself a low-cost homemade mount and posted about it in my OSM diary (was featured in WeeklyOSM too), but have after this changed to suction mounts that several users have described above. I have mostly run sequences with two cameras, one forward pointing, and one reverse, but hope to soon be able to cover a complete 360º with action cams + a 360º cam (360 cams seems to give lower quality images so maintaining the use of action cams for details.

I used a GME mount Harry[/quote]
Ive used GME mounts for years for UHF and VHF antennas. They are metal so built to last. The one you show there are designed to mount on the fender but doesnt have to be a antenna on it
If I remember correctly, I’ve already drive up to 110km/h. And I think that 130km/h is safe.
The speed is not really a problem for the front and back cameras, but for the side one, the rolling shutter is a big problem if objects are too close.
