Re: Sony Unveils the Smallest and Lightest Lidar Depth Sensor
#2A very meandering article, here's the info you want:
~30deg fov 24x24 resolution 940nm IR
50g, approx 3cm^3
max range in 15fps mode @ center of fov, 50% albedo
outdoor 20m indoor 40m
30fps default mode (range expectations not stated for this mode)
5mm accuracy @ 10m (unclear in which mode)
no word on price

It's a cute package, but that resolution is wild. 24x24? I suppose it might have a place in manufacturing automation tasks.
I don't know where you'd have room for one of these but no room for something like the D435 which has a resolution of 1280 × 720 on the depth side and an RGB sensor. Maybe robotic vacuum cleaners or something.

It is like a fancy occupancy sensor, 24x24 over that huge volume and only 15fps.

I've posted the news a few days back with more info but better to go to Sony website for more details [1].

This is still useful if you combine this method with other methods to make depth map more dense and metric e.g. photogrammetry or ML depth estimation model. AFAIK this is how apple depth api works with their lidar.
Here bytedance release very good model that combine their depth anything v2 with such low density apple lidar depth map: https://promptda.github.io/

These are fundamentally different technologies, the camera you linked uses structured light and stereo vision + ML to get depth. It has an order of magnitude less range and an order of magnitude more error. The Sony sensor is time of flight SPAD, it's much closer to giving you a ground truth you can trust than the Intel camera and much more capable of rejecting environmental noise.

#8There are already LIDAR units for drones about that size.[1] About the same weight, better resolution, available now. There are smaller phone time of flight cameras, with better resolution.
Really needs price info. There's good expensive stuff, and not very good cheap stuff, in this space.

#9Wait, haven't iPhones and iPads had lidars for several years now? Aren't they much smaller?

This Sony one looks huge in comparison. Am I missing some fundamental difference between them?

My guess would be that's not "true" LIDAR. It's probably something akin to the Kinect hardware; an infrared pattern is projected, then distance is inferred depending on how it gets distorted, while LIDAR sends photons and measures them back (technically the first does that as well but w/e).
