For the previous decade, the tech trade has been contemplating whether or not self-driving automobiles want LIDAR sensors, cameras, or all the above. LiDAR firm Ouster says it has discovered a brand new reply: placing 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 those present so-called “native colour riders”. These sensors can concurrently seize colour photographs and three-dimensional depth info, performing the features of two sensors in a single.
Ouster CEO Angus Pacala, who mentioned the corporate has spent a decade growing it, was not shy about his ambitions for the brand new product lineup in an unique interview with TechCrunch, calling it “the holy grail of what roboticists have all the time wished.”
“All through human historical past, we have been shopping for LIDAR sensors, shopping for cameras, attempting to grasp that mixture with higher-level reasoning, and losing tons of time on this,” he instructed TechCrunch. “And companies are solely half approach there on the subject of coordinating and converging knowledge streams.”
Ouster’s new sensor adjustments that equation, he mentioned.
“The objective is to eradicate the necessity for cameras. There is no motive why one sensor cannot carry out each features,” he mentioned.
The Rev8 lineup comes at a dynamic second for lidar corporations. There was a wave of consolidation through the years, together with Auster’s acquisition of Velodyne and, extra just lately, the chapter acquisition of Luminar’s property.

On the similar time, the sensor market can be experiencing explosive development. Waymo and others have lastly launched working robotaxis and are quickly increasing. Humanoid and industrial robotic corporations are elevating funding capital and wish sensors to understand the world. Curiosity on this area is so excessive that startups like Boston-based Teradar are rising and experimenting with the sector in fully new methods. (For Teradar, we use terahertz imaging.)
Pacara mentioned colour lidar, which mixes pinpoint depth info with camera-quality picture knowledge, might be significantly worthwhile to robotics stakeholders. Auster mentioned he labored with Fujifilm and imaging science firm DXOMARK to grasp “what it means to make a terrific digital camera.”
The truth is, Pacara claims that Auster’s colour lidar is “improved in some ways with its newest cameras” due to the way in which the corporate already designs and builds its sensors.
Ouster makes use of a so-called “digital LIDAR” structure. As an alternative of analog approaches that require many shifting elements, Ouster makes use of what is called a single-photon avalanche diode (SPAD) detector to seize LIDAR info immediately on a customized chip.
The corporate makes use of this similar SPAD expertise to seize colour picture knowledge with its Rev8 sensor. Pacara mentioned the brand new expertise permits photographs to be captured with increased sensitivity than common cameras.
“48-bit colour, 116 dB dynamic vary, equal to mega pixel decision. These are the gold normal numbers that make this a terrific digital camera. But it surely simply occurs to be delivered as an information stream that’s pre-fused as a 3D colorized level cloud,” he mentioned. “You’ll be able to really use the information as a digital camera stream, and that is one of many strengths of this method, and relying on the ahead considering of the popularity workforce, you should utilize simply the LIDAR knowledge stream, you should utilize simply the digital camera knowledge stream, you should utilize a pre-fused knowledge stream.”
Pacala mentioned the corporate has already shipped samples to present clients and is at the moment accepting orders. He’s significantly pleased with the OS1 Max sensor, which he believes is “the most effective long-range lidar within the trade,” he mentioned. It could possibly see as much as 500 meters in all instructions and is “considerably” smaller than different long-range riders.
“We had long-range LiDAR, but it surely wasn’t clearly higher than anything,” he mentioned. “It is a big leap ahead for Ouster. I believe it means we’ll begin to see much more of it in high-speed robotic trucking and robotaxis purposes. I believe quite a lot of drone-related merchandise will migrate to OS1 Max.”
Different new LIDARs constructed on the Rev8 platform will embrace OS0, OS1, and OSDome, in accordance with the press launch.
Ouster is not the one firm to begin speaking about coloured riders. Final month, Chinese language firm Hesai unveiled its personal colour lidar platform and mentioned it will enter mass manufacturing by the top of this yr. Different corporations, resembling Innoviz, have additionally pitched their very own tackle “colour LIDAR” up to now.
Nonetheless, most different gamers attempting to “fuse” cameras and lidar sensors are basically placing them in a field collectively, Pacala says. The strategy taken by Ouster (and Hesai, to be honest) is to place the lidar and imaging expertise on the identical chip.
It will considerably scale back the quantity of labor Ouster’s clients must do to grasp competing sensor streams, and finally result in these clients avoiding cameras altogether, Pacala mentioned. On the similar time, it is cheaper and smaller than Ouster’s earlier expertise.
“That is one thing that basically adjustments the worth proposition of what we promote to clients from this level ahead,” he instructed TechCrunch.
