Visual Positioning System for Navigation

[ppoirier]

Hello,
We had some discussion related to this topic here:

Is there a long range stereo camera that can be used for altitudes up to 200 meters?

@seattleiteFPV , @Mustafa_Gokce I want to do autonomous navigation. my initial thought was to use VIO with a monocular camera, but after couple of searching it turns out, VIO especially with monocular cameras are not robust and are usually used in confined spaces like indoors, when we go outdoors, and especially when our drone should fly at varying altitudes (based on how high the obstacles are or what the mission is) its not a good idea. That’s why I searched the commercial drones and noticed…

Basically we are talking about a TERCOM inspired navigation system.
