The tech trade has spent the decade asking whether or not self-driving vehicles want lidar sensors, cameras, or the entire above. Lidar corporate Ouster says it has a brand new resolution: put them each in the similar sensor.
On Monday, the San Francisco-based corporate introduced a brand new lineup of lidar sensors it calls “Rev8,” all of which give so-called “local colour lidar.” Those sensors are in a position to taking pictures colour imagery and third-dimensional intensity knowledge on the similar time, doing the paintings of 2 sensors in a single.
Ouster CEO Angus Pacala mentioned the advance has been a decade within the making at his corporate, and he wasn’t shy about his ambitions for the brand new product lineup in an unique interview with TechCrunch, calling it the “holy grail of what a roboticist has all the time sought after.”
“For all of human historical past, it’s been: you purchase a lidar sensor, you purchase a digicam, and also you attempt to make sense of the combo with some upper stage reasoning, and waste a huge period of time doing this,” he informed TechCrunch. “And corporations most effective get actually midway there in the case of calibrating and fusing the information streams.”
Ouster’s new sensors, he mentioned, trade this equation.
“The purpose is to obviate cameras. There’s no explanation why that one sensor can’t do each,” he mentioned.
The Rev8 lineup arrives at a dynamic second for lidar corporations. There was a years-long wave of consolidation going down, with Ouster purchasing Velodyne, and Luminar’s property lately getting received in chapter.

On the similar time, the marketplace for sensors is exploding. Waymo and others have in any case deployed operating robotaxis and are scaling briefly. Robotics corporations — humanoid and business — are hoovering up funding greenbacks and want sensors to understand the arena. There’s such a lot pastime within the area that new corporations like Boston-based Teradar are stoning up and trying out the waters with fully new modalities. (In Teradar’s case, it’s the use of terahertz imaging.)
A colour lidar that mixes pinpoint intensity knowledge with camera-quality symbol knowledge might be particularly precious to the robotics avid gamers, Pacala mentioned. And he mentioned Ouster labored with Fujifilm and symbol science corporate DXOMARK to grasp “what it way to construct an ideal digicam.”
Actually, Pacala claims Ouster’s colour lidar is “bettering in some ways on a contemporary digicam” due to the best way the corporate already designs and builds its sensors.
Ouster makes use of so-called “virtual lidar” structure. As a substitute of the analog method, which comes to many transferring portions, Ouster captures the lidar data at once on its customized chip the use of what’s referred to as unmarried photon avalanche diode (SPAD) detectors.
The corporate is the use of this similar SPAD era to seize the colour symbol knowledge within the Rev8 sensors. Pacala mentioned this novel methodology permits its symbol seize to be extra delicate than an ordinary digicam.
“It’s 48-bit colour, 116 dB of dynamic vary, like mega pixel answer. Those are best line numbers that make it pound for pound excellent digicam. But it surely simply so occurs it’s coming as a pre-fused knowledge move as a three-D colorized level cloud,” he mentioned. “You’ll in fact use the information as a digicam move as neatly, however it’s that’s one of the vital powers of the program, is you’ll use simply the lidar knowledge move, you’ll use simply the digicam knowledge move, or you’ll use the pre-fused knowledge move, relying on how more or less forward-thinking your belief crew is.”
Pacala mentioned his corporate has already shipped samples to present consumers and that it’s now taking orders. He mentioned he’s in particular happy with the OS1 Max sensor, which he mentioned he considers to be “the trade’s very best lengthy vary lidar.” It will probably see 500 meters in all instructions and is smaller than different lengthy vary lidar “through a large margin.”
“We’ve had a protracted vary LiDAR, however it hasn’t been identical to obviously a reduce above the entirety else,” he mentioned. “That’s a large jump for Ouster. I believe it signifies that we’ll begin to see it a lot more on high-speed robo-trucking, robotaxi packages, I believe numerous drone stuff will transition to the OS1 Max.”
Different new lidars constructed at the Rev8 platform will come with the OS0, OS1, and OSDome, in keeping with a press free up.
Ouster isn’t the one corporate that has began speaking about colour lidar. Final month, Chinese language corporate Hesai introduced its personal colour lidar platform that it says will input mass manufacturing through the tip of this yr. Different corporations, like Innoviz, have in the past pitched their very own takes on “colour lidar.”
Pacala says maximum different avid gamers seeking to “fuse” cameras and lidar sensors are mainly packaging them in combination in a field, despite the fact that. The method Ouster (and, to be honest, Hesai) is taking is striking the lidar and imaging tech at the similar chip.
This dramatically cuts down at the quantity of labor Ouster’s consumers need to do to make sense of the competing sensor streams, Pacala mentioned, and it additionally units the ones consumers as much as sooner or later eschew cameras altogether — all whilst being less expensive and smaller than Ouster’s earlier era.
“This is more or less basically converting the price proposition of what we’re promoting to a buyer from this level ahead,” he informed TechCrunch.
