Cortexia has developed an AI-supported technology for smart cities that enables cities to be cleaned more efficiently by collecting cleanliness data in the cityscape. With the Cortexia solution, cameras are mounted on cleaning vehicles that use computer vision to precisely recognize different types of dirt such as leaves, chewing gums or cigarette butts in public spaces along the roads. Their images are analyzed directly on a mini-computer attached to the vehicle. The software then displays the cleanliness of each street on a city map.
