Spartan Radar fog test

In the short video below, we’ve compared the performance of LiDAR, a camera, and our Hoplo Radar under foggy conditions. As the video demonstrates, Hoplo maintains sight of all the objects in the room, even as the camera and LiDAR get lost in the mist. Stay tuned for more exciting demonstrations of Spartan’s innovative advances in perception tech and sensor software.

All weather performance is essential for any autonomous vehicle sensor. The radar sensor can also see much further in rainy, foggy or snowy conditions. This is just by virtue of the wavelength a radar sensor uses and how that wavelength interacts with small particles floating in the air.

You’re viewing a comparison of the performance of LiDAR, a camera, and our Spartan Hoplo radar in foggy conditions. On the right we’ve overlaid the LiDAR point cloud which is represented by the colorful points, and the radar data, which is represented by the white dots, and which currently outputs the five largest objects in the scene. On the left, we’ve overlaid the radar data over a camera video stream, with a circle color coded by distance identifying the objects that the radar is detecting. As the fog fills the room you can see that the camera and LiDAR both lose sight of the objects in the scene as the fog clouds both the video stream and the LiDAR point cloud. Meanwhile, our Hoplo radar is unaffected by the fog and maintains sight of all objects in the room.
