Preview of upcoming Dronecode/PX4 multi-camera VIO feature

Visual Inertial Odometry (VIO) is a way to do position estimation and navigation without GPS, which is both useful for drones inside and for self-driving cars. Coming to the next release of the Dronecode/PX4 stack.

I remember seeing this last year... any news of implementation in the px4 stack?

PX4 stack doesnt fly with GPS properly, now they are trying without GPS?)

PX4 1.7 will be released next week. The VIO stack will be released in 1.8, in Q1

That video looks like SLAM, is that coming from px4?

Thats a handheld demo from a year ago.

Does it have anything to do with px4?  Is it using IMU from px4?  I guess it's not doing the visual processing on the flight controller?

Yes, it will be coming in the PX4/Dronecode release. It uses the Intel Aero Vision 3-camera system and works on the Intel Aero board running PX4

It may be useful to clarify what is coming. The video posted uses 3 camera pairs, not 3 cameras. I look forward to seeing vio in a production flightstack, but am quite frustrated at intentionally misleading information, particularly from Chris. I understand the motivation to promote DroneCode, and follow progress closely- I fly both px4 and ArduPilot. But having to second guess and challenge any announcement doesn’t support my attempts to maintain an open mind.

@Chris that's a vague answer.  I'm interested in px4 and what it has to offer, particularly around vision capabilities.  Hopefully someone will post more useful information closer to the release.
