Waymo, the self-driving technology company owned by Google's parent company, Alphabet, released a dataset containing sensor data collected by their autonomous vehicles during more than five hours of driving. The set contains high-resolution data from lidar and camera sensors collected in several urban and suburban environments in a wide variety of driving conditions, and includes labels for vehicles, pedestrians, cyclists, and signage. The Waymo team announced the release of the Waymo Open Dataset in a blog post, describing it as "one of the largest, richest, and most diverse self-driving datasets ever released for research." The data was collected by Waymo's vehicles operating in the USA in Phoenix, AZ, Kirkland, WA, Mountain View, CA and San Francisco, CA, at various times of day and night, and in good and bad weather. The dataset consists of 1,000 segments of 20 seconds each, collected at 10Hz (i.e., 200,000 frames) which contain: Waymo also released a Google Colab notebook containing tutorials and a GitHub repository containing TensorFlow helper-code for building models.
