Researchers at Waymo and Uber presented new technologies at the Conference on Computer Vision and Pattern Recognition 2020 that aim to make their self-driving systems safer and more reliable.
Waymo’s Drago Anguelov demonstrated ViDAR, a camera and range-centric framework created in partnership with Google Brain.
ViDAR uses motion parallax to learn three-dimensional geometry from image sequences, like frames captured by car-mounted cameras.
The technology spurred the creation of models that, for instance, estimate depth from camera images and predict the direction that obstacles, like pedestrians, will travel.
Meanwhile, Uber’s Advanced Technologies Group’s Raquel Urtasun highlighted the V2VNet system, which allows autonomous cars to share information, such as timestamps and location, over the airwaves.
An artificial intelligence model helps compensate for time delays and selects only relevant data, like LiDAR sensor readings, from the data sets.
V2VNet’s error rate was 68% lower than that of single vehicles.
