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

Raspberry Pi gets a comeback as the Star Trek communicator with OpenClaw! Raspberry Pi was popular in the 2010s and now faces a comeback as the personification of OpenClaw in a Tamagotchi shape - it listens, it thinks and it even talks! And it is not even that expensive! Sebastian Volkl created his Raspberry Pi project with just $100. Do you want your own OpenClaw Tamagotchi? #tamagotchi #openclaw #raspberrypi #ai #tech Sebastian Völkl

🇮🇷 Iran’s “low-cost” cruise missile navigation is smart layering They combine 3 layers: -Cheap commercial GPS for basic positioning -Inertial navigation to keep flying without signals -Terrain matching to correct errors using preloaded maps and ground scans The key is terrain matching, where the missile compares the ground below with stored elevation maps and continuously corrects its path in real time, even if GPS is jammed. Nothing revolutionary. This tech exists for decades. What matters is the approach: cheap components, open data, and multiple backups working together. End result: not perfect, but reliable enough to hit targets without needing a military satellite network. Source: loadedlore YT

Haven't seen any demos of using vibe coding to prototype gadgets like this So I made one. Everything here is generated with code Parts of the code and logic can even be reused on a Raspberry Pi to build the real thing Some tips ↓

Total insanity. This is using an adaptive LOD scheme in sparksjs (not merged yet). The entire scene has 16million splats and this is real time navigation ... 😱😱

We've mapped our 28,000 sq ft office and built this fly-through in real-time on-device using NVIDIA Orin Nano 4GB and 5 consumer-grade cameras (<$10 at scale). This exact flythrough feature is now live to everyone in the Matic App. Designed for homes, our sensing stack and algorithms scale to larger spaces such as warehouses, malls, and more!

I saw Alex Aljoe do this with Luis Diaz earlier in the season and was hugely impressed. It’s such a skill to talk and translate in real time whilst live on camera with producers in your ear the whole time.
