Ouster, a San Francisco-based lidar manufacturer, has unveiled its new Rev8 lidar sensors, aiming to combine the functionality of lidar and traditional cameras into a single device. This innovation comes amidst a decade-long debate within the tech industry regarding the necessity of optical sensors for self-driving vehicles. Ouster’s Rev8 lineup features “native color lidar,” which captures both colourful images and 3D depth data simultaneously, effectively merging two sensors into one.
CEO Angus Pacala highlighted the significance of this development, asserting that the Rev8 represents a long-awaited breakthrough in robotics. Historically, integrating lidar with cameras required hefty calibration efforts to make sense of data from two distinct streams, often leading to inefficiencies. Ouster’s new technology aims to streamline this process, with Pacala stating that the goal is to render traditional cameras unnecessary.
At a time when the lidar sector is undergoing considerable consolidation—including Ouster acquiring Velodyne—market demand for sensor technology is booming. Companies such as Waymo are deploying operational robotaxis, while robotics ventures across various applications are securing substantial investments and require advanced sensing capabilities. Ouster’s collaboration with Fujifilm and DXOMARK has led to the development of a lidar system that Pacala claims outperforms modern cameras, achieving superior image quality through its architecture.
Utilising “digital lidar” technology, Ouster’s sensors operate on custom chips equipped with single photon avalanche diode (SPAD) detectors, capturing both lidar data and colour images more sensitively than standard cameras. The Rev8 sensors are capable of producing 48-bit colour and possess a dynamic range of 116 dB. This allows users to select between different data streams, whether it be purely lidar, only camera data, or a combined version, based on their specific needs.
Early orders for the Rev8 have already begun, with Pacala particularly proud of the OS1 Max sensor, which he claims to be the best long-range lidar on the market. Capable of detecting objects 500 metres away while being smaller and more efficient than previous models, the OS1 Max is expected to enhance applications in robo-trucking and drone technologies.
Ouster is not alone in developing colour lidar; competitors such as China’s Hesai are also making strides in this area, with plans for mass production of similar technology. However, where Ouster differentiates itself is in tightly integrating lidar and imaging technology on the same chip, thus simplifying data processing for users.
Overall, this new approach not only decreases processing complexity and cost but also enhances the fundamental value offered to customers, suggesting a significant shift in the lidar market landscape going forward.
