Mapillary, a Swedish technology firm, has published the Mapillary Vistas Dataset consisting of 25,000 annotated street-level images to help researchers train autonomous driving systems. The images, taken at different times of the day and in varying weather conditions, come from 190 countries and Mapillary groups them into 100 different categories, including “bike lane,” “pedestrian area,” and “traffic island.” The Mapillary Vistas Dataset is free for both academic and commercial research.
