摘要: Inventory of road signs are part asset management systems for a roadway agency. Detection, recognition, and positioning critical components system. In this research stereo vision based system is developed to conduct automated sign inventory. Such techniques may be also used detect other objects on the or by roadside. The in real-time integrates synchronizes data streams from multiple sensors high-resolution cameras, differential global receivers, distance measurement instrument, inertial unit. Algorithms sets determine positions moving vehicle orientation cameras. key findings include feature extraction analysis that applied detection recognition right-of-way (ROW) images, implementing tracking algorithm candidate region among image frames so same not counted more than once an sequence, technique compute world coordinates stereo-paired ROW images. Particular employed all acquisition board vehicle. This advanced alternative traditional inventory methods terms safety efficiency. It anticipated future studies employ automatically presence man-made around areas security purposes.
