GPS-free visual-inertial navigation in real time on Raspberry Pi 5 with a consumer-grade IMU and camera (and this is not even the slowest CPU this runs on!)

Features of the new Spectacular AI SDK 1.38 include: ⭐ ONNX-based VPS acceleration: allows full VIO+VPS operation even on Cortex A53s ⭐ Built-in IMU-camera calibration Python tool, based on our fork of Basalt (separate post to follow) For more details:

mfw i need to drop ~2kg of hospital supplies on remote hikers in a famously GPS spotty area

This is truly amazing work. I have a friend in the military that was talking about GPS denied environments being a challenge. I have to imagine people like Anduril are going to integrate this into our military systems. $60 of compute + $18 barometer + $5 camera + IMU. Just wow. Sadly, commercial and civilian aviation near war zones can be subject to GPS denial as well. IMO, this is a technology that @doge needs to look at with regard to improving aviation safety. LFG!

What's the ratio of data : navigable area here? Assuming you have either map data or like, latents of map data that you're loading in a mission dependent way right? Like this isn't a pi-sized blob of data that can navigate all of Earth right?

This demo used a 100 x 100 km² map, which easily fits into an SD card (a 1 km x 1000 km map would take practically the same space). The ballpark size is "gigabytes" and is adjustable with a few settings that allow balancing between CPU, disk and accuracy.

Could this be also used for marine navigation? Think celestial navigation with a INS / IMU.

Good question. This solution is not suitable for marine navigation, since VIO does not work at sea. Combining IMU / INS with star trackers probably works in the marine context, but it's not the same thing as this method

Are you developing this for weapons? There seems to be no real usefulness for this in the commercial industry

bookmarked. what's list of benefits of it? more accurate? or cheaper?

raspi5 is a beast.
