The tech business has spent the final decade asking whether or not self-driving vehicles want lidar sensors, cameras, or all the above. Lidar firm Ouster says it has a brand new reply: put them each in the identical sensor.
On Monday, the San Francisco-based firm introduced a brand new lineup of lidar sensors it calls “Rev8,” all of which provide so-called “native coloration lidar.” These sensors are able to capturing coloration imagery and three-dimensional depth data on the similar time, doing the work of two sensors in a single.
Ouster CEO Angus Pacala stated the event has been a decade within the making at his firm, 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 wished.”
“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 mix with some increased stage reasoning, and waste an unlimited period of time doing this,” he advised TechCrunch. “And firms solely get actually midway there when it comes to calibrating and fusing the info streams.”
Ouster’s new sensors, he stated, change this equation.
“The objective is to obviate cameras. There’s no motive that one sensor can’t do each,” he stated.
The Rev8 lineup arrives at a dynamic second for lidar corporations. There was a years-long wave of consolidation occurring, with Ouster shopping for Velodyne, and Luminar’s assets recently getting acquired in chapter.

On the similar time, the marketplace for sensors is exploding. Waymo and others have lastly deployed working robotaxis and are scaling rapidly. Robotics corporations — humanoid and industrial — are hoovering up funding {dollars} and want sensors to understand the world. There’s a lot curiosity within the house that new corporations like Boston-based Teradar are popping up and testing the waters with entirely new modalities. (In Teradar’s case, it’s utilizing terahertz imaging.)
A coloration lidar that mixes pinpoint depth data with camera-quality picture information might be particularly helpful to the robotics gamers, Pacala stated. And he stated Ouster labored with Fujifilm and picture science firm DXOMARK to grasp “what it means to construct an awesome digicam.”
In reality, Pacala claims Ouster’s coloration lidar is “bettering in some ways on a contemporary digicam” due to the way in which the corporate already designs and builds its sensors.
Ouster makes use of so-called “digital lidar” structure. As an alternative of the analog strategy, which includes many transferring components, Ouster captures the lidar data straight on its customized chip utilizing what’s generally known as single photon avalanche diode (SPAD) detectors.
The corporate is utilizing this similar SPAD expertise to seize the colour picture information within the Rev8 sensors. Pacala stated this novel method permits its picture seize to be extra delicate than a traditional digicam.
“It’s 48-bit coloration, 116 dB of dynamic vary, like mega pixel decision. These are prime line numbers that make it pound for pound good digicam. Nevertheless it simply so occurs it’s coming as a pre-fused information stream as a 3D colorized level cloud,” he stated. “You may truly use the info as a digicam stream as effectively, but it surely’s that’s one of many powers of this method, is you should utilize simply the lidar information stream, you should utilize simply the digicam information stream, or you should utilize the pre-fused information stream, relying on how type of forward-thinking your notion workforce is.”
Pacala stated his firm has already shipped samples to present prospects and that it’s now taking orders. He stated he’s significantly happy with the OS1 Max sensor, which he stated he considers to be “the business’s greatest lengthy vary lidar.” It might see 500 meters in all instructions and is smaller than different lengthy vary lidar “by a giant margin.”
“We’ve had a protracted vary LiDAR, but it surely hasn’t been identical to clearly a reduce above every little thing else,” he stated. “That’s a giant leap for Ouster. I believe it implies that we’ll begin to see it rather more on high-speed robo-trucking, robotaxi purposes, I believe loads of drone stuff will transition to the OS1 Max.”
Different new lidars constructed on the Rev8 platform will embrace the OS0, OS1, and OSDome, in line with a press launch.
Ouster isn’t the one firm that has began speaking about coloration lidar. Final month, Chinese language firm Hesai introduced its own color lidar platform that it says will enter mass manufacturing by the top of this 12 months. Different corporations, like Innoviz, have beforehand pitched their very own takes on “coloration lidar.”
Pacala says most different gamers attempting to “fuse” cameras and lidar sensors are mainly packaging them collectively in a field, although. The strategy Ouster (and, to be truthful, Hesai) is taking is placing the lidar and imaging tech on the identical chip.
This dramatically cuts down on the quantity of labor Ouster’s prospects should do to make sense of the competing sensor streams, Pacala stated, and it additionally units these prospects as much as finally eschew cameras altogether — all whereas being cheaper and smaller than Ouster’s earlier expertise.
“That is type of essentially altering the worth proposition of what we’re promoting to a buyer from this stage ahead,” he advised TechCrunch.
