Bicycling for Mapillary

Posted by smathermather on August 2, 2014

We’ve got two wheels now, baby! (and I’ve refined this a bit from a bungee only setup).  Here’s my rig for bicycling for Mapillary photos.  This uses the same gimbal for stabilizing and leveling the photos, so it should have similarly great output.

Mapillary output yet to come for this one.  In the mean time, you can watch the camera gimbal come alive:

Also you can look at the stabilized unicycle versions here: https://mapillary.github.io/mapillary_examples/seven_hills.html and here: http://www.mapillary.com/map/im/16/41.38742655884223/-81.69359564781189

Unicycling for Mapillary

Posted by smathermather on August 1, 2014

I really dig the crowd-sourced street-view service, Mapillary, and like to contribute to it, but doing a good job of getting blur-free images is a little tricky. This is double true in dark, under forest canopy trails. So, we solved it with some technology. Enter, a GoPro camera, a gimbal for an RC copter (drone), and some old bicycle parts:

The gimbal is a two axis gimbal which keeps the roll and pitch constant to 0.01-degrees, so it eliminates shake, and keeps the orientation of the photos consistent. The one we got costs around $180, although now I find them for as low as $130 (not my video):

And then we attached it to a makeshift unicycle:

Some post-processing to match it to our GPS and voila!
