Adaptive reflector code on roadside for acquiring information by infrared laser range scanner

Abstract

We have proposed an information acquisition method with detecting the reflector code on roadside by using infrared laser range scanner. The scanner on vehicle scans the reflector code on roadside while traveling. However, we cannot change the code pattern according to the road information, GPS location and so on. Hence, we propose an adaptive reflector code by switching infrared LED to express appropriate information. Through some experiments, we show that the vehicle can obtain different information from roadside according to the use case.
