研究目的
Proposing a code change method by switching infrared LED to allow vehicles to obtain different information from roadside according to the use case.
研究成果
The proposed code changing method by switching infrared LED on the reflector code is feasible, as demonstrated by the ability to detect the infrared LED ON and OFF states to recognize one bit of information. Future work should focus on increasing the number of LEDs to enable dynamic code changing according to use cases.
研究不足
The study is conducted in a controlled environment without direct sunlight, which may not fully represent all real-world conditions. The number of LEDs used is limited, suggesting a need for future work to increase the number of LEDs for dynamic code changing.
1：Experimental Design and Method Selection:
The study involves constructing a 2D reflector code composed of corner cube mirror reflector, glass beads reflector, white board sheet, and LED on black vinyl chloride plate. The infrared laser radar on the vehicle scans the reflector code while traveling.
2：Sample Selection and Data Sources:
The experiments are conducted in a sunny day with the infrared laser radar set without direct light from the Sun.
3：List of Experimental Equipment and Materials:
Infrared laser radar, corner cube mirror, glass beads, white board sheet, black vinyl chloride plate, infrared LED.
4：Experimental Procedures and Operational Workflow:
The vehicle travels along the reflector code on roadside at speeds of 5 and 10 km/h, with the radar detecting different positions of each reflector.
5：Data Analysis Methods:
The received signal strength indicator (RSSI) in case of ON and OFF of the LED are compared to distinguish the ON and OFF states.
