Abstract:
A seamless vehicle localization capability with high accuracy and integrity is essential for the safe operation of automated vehicles. This study integrates a map-matching based detection scheme and a low-cost Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU) system to enhance the localization capability in a challenging environment. Existing vehicle navigation systems typically use a GNSS/IMU navigation suite to provide position, velocity, and attitude. Such a navigation suite is subject to the error characteristics of the IMU and the operating environment of the GNSS. If the GNSS signals are affected for a long period of time and the quality of the IMU is not well calibrated, erroneous navigation results may occur. It is noted that a challenging environment is featured with some landmarks such as traffic lights. The significant visual feature can be detected robustly by using a deep learning model in a whole day time, which means the availability of the proposed method is better than previous vision-based localization schemes. The paper investigates the fusion of a low-cost GNSS receiver, IMU, vehicle odometer, monocular camera, and an HD map to render seamless navigation. The system is implemented in a vehicle and tested at Taiwan CAR Lab. The effectiveness of the proposed scheme is demonstrated.
