alt Hacker NewsI have a degree in Computer Vision, and, whether Pickle is lying about various capabilities or not, this guy is talking completely out of his ass and a whole lot of what he says is just extremely idiotic.
> tracking blah blah 6DoF blah blah IMU
This whole section is just wildly false. Tracking like shown in the video is easily done with just a camera, 1980s-era sparse optical flow, and basic fucking geometry. No IMU needed. People have been doing far more complex and stable motion tracking with no more input than single camera video for literally decades. And this device doesn't just have a camera; it has two HD stereoptic cameras, so they also get a depth map. You can absolutely do what they show with the hardware that Pickle claims is in the glasses.
(If you want a fantastic example, see the intro sequence to the movie Stranger Than Fiction from 2006.)
> It would take time to affix an open source SLAM pipeline and even more for them to build their own.
And this is a complete non sequitur, as SLAM is also not needed for what they show in the video. Nothing shown requires mapping the area. It's also a joke to say that it would "take time to affix an open source SLAM pipeline" unless by "time" he means a few minutes.
> This would indicate either the software is using real-time depth tracking blah blah
The glasses have fucking binocular cameras in them! What the fuck else would they be for?
> But in the photos of Pickle 1, there is no sign of any spot to charge the device.
There is zero reason whatsoever to believe that those images are photos of the final product and not renders or props. It's like he's never seen marketing material before.
I can't even with this.
This guy's LinkedIn bio says "Aug 2022 - Mar 2023: Attended UVA as a first year studying economics and commerce before dropping out to build in VR full time." So it seems he's a self-important child with zero background. That explains a lot tbh.

Given the amount of tech I own that is supposed to do this (higher end VR headsets with hand tracking, AR glasses with environmental tracking, etc.), I wouldn't dismiss the author's claims.
But I'd be interested in your examples that can achieve what Pickle is offering in a single pair of glasses.
If you really believe Pickle's claim so much and disbelieve OP's analysis so much, you should contact Pickle's CEO to get more info from him. Once you build more trust, you should join the CEO and take on OP's bet.
(I probably should have said sparse feature tracking and not optical flow. People tend to get the wrong idea about what optical flow fundamentally requires. Spatial regularity and density are not inherent but people may assume they need to be.)
Well I hope you never get into this business because I doubt your glasses will work in the dark or on red eye flights.

Not with imperceptible latency
SLAM is needed for world locked content.
>1980s-era corner feature detection, and basic fucking geometry
Which are pieces of how SLAM works.
>You can absolutely do what they show with the hardware that Pickle claims is in the glasses.
World locked content is not novel. Existing glasses can do it today. The claim is that Pickle didn't build it. The obvious answer would be that they are using what Qualcomm or someone else built it as opposed to Pickle building all of this within a month.
