(video) Lidar vs. camera in the rain

Have a look at how the OS1 lidar sensor performs in the rain. We got some of the first rains of the winter last week, so we took a drive through San Francisco; you can see the camera feed from a GoPro on the left.

In the first view, the three images in the top right are visuals that are natively output by they lidar sensor — no camera involved. You can see that water doesn’t obscure the lidar images, even though there are water droplets on the lidar sensor window.

Other observations to note are the way the sensor doesn’t pickup the rain drops falling due to the large aperture of the sensor, and also how the range is reduced on the roadway due to the wet road acting as a specular mirror-like surface, reflecting less light back to the sensor.

Ouster builds high-resolution 3D lidar sensors that are powering autonomy in the industrial, smart infrastructure, robotics, and automotive industries. We are a team with deep knowledge of semiconductors, optics, signal processing, computer vision, and high-volume manufacturing. Our breakthrough digital lidar technology produces sensors that are high-resolution, reliable, and affordable. We are working to make 3D sensing lidar technology ubiquitous throughout our everyday lives.
