Abstract:
Automatic traffic control requires various types of sensors including GPS, LIDAR, RADAR, and camera sensors. Theses sensors are used together to detect, track and locate objects of interest such as vehicles, pedestrians, and traffic signs. A camera plays a main role in traffic control because it offers a cost-effective solution for object detection and tracking. This talk introduces the operation principle of a camera sensor capturing an image, enhancing its quality, and compressing the data for transmission and storage. The characteristics for automotive applications are discussed and then recent advances in this research field including the use of AI techniques are presented. Object detection and tracking with cameras are introduced together with the localization of the detected object. This talk also presents the experiences to use cameras for automatic traffic control for self-driving vehicles and discusses the effectiveness of traffic control with cameras.
