Treffer: Speed traffic sign detection on the CARLA simulator using YOLO

Treball fi de màster de: Master in Intelligent Interactive Systems ; Tutor: Federico M. Sukno ; Research on the self-driving and on the autonomous vehicles field is constantly increasing. The administrations are putting all their efforts to raise awareness among drivers about the responsibility that driving a vehicle implies. By their side, researchers are working hard to make vehicles as safe as possible in order to decrease the number of fatal accidents in our roads. Around 30% of these accidents have a key factor: speeding. Since some decades ago until our days, speeding has become a widely investigated topic by the large automotive companies. The European Union (EU) has recently announced new measures that will be taken in 2022 aiming to reduce car accidents. The most relevant one, is the measure that forces new vehicles manufactured at that year to have an intelligent speed assistance device integrated to make the driver aware when exceeding the speed limit of the road. Unfortunately, the oldest cars will remain without that system. The aim of this project is to contribute to this research by integrating into a realistic driving simulator a system able to detect and recognise the speed traffic signs of the road, taking decisions that help the user make the driving process easier and safer. The simulator used in this study is the CAR Learning to Act (CARLA), an open-source simulator for autonomous research that mainly consists of two modules: the CARLA Simulator and the CARLA Python API module. To detect its road signs, a cutting-edge object-detection algorithm is used: the You Only Look Once (Yolo) algorithm. Instead of using a sliding window over several locations within an image, Yolo sees the entire image during the training and testing phases encoding contextual information about the object classes as well as their appearances. This characteristic allows it to be extremely fast while an image is being evaluated. Identifying the speed traffic signs of a road can have a wide range of utilities. In this ...
