SPEED ESTIMATION, DETECTION AND RANGING USING VISIBLE LIGHT IN VEHICLES (OSU # 2017.58)
OSU researchers have developed an advanced method named ViLDAR (Visible Light Detection and Ranging). In this method, the speed of a vehicle is detected using the vehicle’s LED headlight intensity information acquired by a photo-detector (PD) (Figure 1). The experimental results show that ViLDAR method outperforms the traditional RADAR/LiDAR methods (that uses radio frequencies (RF) or laser signals) in speed accuracy for a wide range of incidence angles between vehicle and PD (Figure 2).
