Abstract:In the field of Intelligent Transportation Systems (ITS), traditional combinations of single radar and checkpoint cameras suffer from high costs and difficulties in data fusion. The radar-visual integration system, which integrates millimeter-wave radar and cameras, optimizes costs and deepens data fusion, gradually becoming a key device in the perception layer of ITS.
