SLAM is not required to do what is shown in the video. As is an IMU. And an IMU is also not required for SLAM. Everything about the blog post is factually wrong.

> Having memory of what existed before implies you have a form of a map

Once again, you're just wrong here. Image feature correspondence works even without any spatial mapping. Once again, you're getting things backwards. You need to find correspondences before you can begin to make a map, not the other way around!

Anyway, I don't have the energy to argue more with someone who confidently doesn't actually know what they're talking about. So, good luck, have fun.

I 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…

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.

Pickle's capability claims don't even need to be true for OP's "analysis" to still be extremely factually incorrect on many levels. Also I consider gambling to be on the balance a bad thing and have no desire to encourage it.

> 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. Not with imperceptible latency

(nb. 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.)

First of all, did you watch the video? (the whole thing is kinda annoying and long, but the part in question here is only about 3 seconds so it's worth looking) Two points about the video: 1) The positioning of the overlay is noticeably unstable in relation to the apparent camera motion, so it doesn't even show what the OP claims it does. 2) You don't have any way to know what the latency is because of that.

Anyway, yes even with, and even in the form factor if you optimize for the right things. The kind of simple feature tracking that can accomplish what's shown in the video was real-time in like 2005, and there have been significant hardware and algorithmic advancements in the past 20 years.
