World’s first native color LiDAR gives machines human-like vision

[hist78]

"For years, machines have navigated the world color-blind. LiDAR sensors – the laser-based eyes of self-driving cars, industrial robots, and inspection drones – build precise 3D maps of their surroundings, but everything is built of monochrome geometric shapes. Ouster's new Rev8 sensor family aims to change that, not by bolting a camera onto a LiDAR unit, but by fusing color directly into every point of data the sensor captures."

"The flagship model of the Rev8 family is the OS1 Max, a 256-channel sensor with a detection range of up to 200 m (656 ft) at 10% reflectivity – meaning it can spot surfaces that absorb most of the light hitting them – and up to 500 m (1,640 ft) under optimal conditions. Its field of view spans 45 degrees vertically and 360 degrees horizontally, and Ouster claims it doubles both the range and resolution of its previous generation, the Rev7."

I guess in this timeline, color cameras haven't been invented yet?

(not a poke at you hist78 - just knocking the marketing of this Lidar company )

Cameras have difficulties under heavy snow, rain, or fog for FSD. They are also challenged by direct sunlight conditions, such as during sunrise or sundown. LiDAR with color capability can greatly improve the accuracy and safety of FSD.

FWIW, it's not as clean as a scenario as it sounds -- Lidar also has issues in these scenarios, too:

“While lidar works well on clear days, it can be unreliable in foggy, rainy, or snowy weather—creating a potential hazard for all road users,” says Will Northrop, professor in the Department of Mechanical Engineering and the project’s principal investigator.

..

The challenge with Lidar + Camera Vision is, as the amount of input increases, the compute power required to 'resolve' and drive the car properly also increases substantially (perhaps more than 2X because of the need to combine and deconflict data).

I agree more sensors should mean more safety, but 6-8 cameras + software that doesn't get distracted should be able to beat human eyes and reaction times for overall safety - especially given cameras can be coated and tuned to see better in low light and snow conditions than human eyes through a windshield).

It was published by a research team at the University of Minnesota in August 2022 (the research itself was probably completed in March 2022). Four years later, I’m wondering whether the analysis would be different given the advances in technology.

Can Automated Vehicles "See" in Minnesota? Ambient Particle Effects on LiDAR

This project will use a combination of laboratory experimentation and road demonstrations to better understand the reduction of LiDAR signal and object detection capability under adverse weather conditions found in Minnesota. It will also lead to concepts to improve LiDAR systems to adapt to...
