Taillight Detection Algorithm Based on Four Thresholds of Brightness and Color

This paper proposes a new vehicle taillights detection algorithm for the night view rear-end collision alarm system of smart vehicle.The algorithm combines with routine geometry parameters,makes use of four thresholds of brightness and color to detect vehicle taillights.The TB_L is used to locate the suspected taillights facular areas,the routine geometry parameters are employed to check and eliminate the suspected taillights facular areas,the TRP_L and TBP are adopted to determine the facular areas of bright taillights,the TRP_H is used to determine the facular areas of dim taillights.Experimental results show that the algorithm can detect taillights accurately and quickly.
