A lasers and cameras calibration procedure for VIAC multi-sensorized vehicles

Abstract

This paper proposes an efficient calibration procedure designed for the vehicle prototypes involved in the VisLab Intercontinental Autonomous Challenge [1]. The perception system is based on laser rangefinders and cameras, for their complementary purpose. An high precision pose estimation must be carried out by a very precise calibration procedure, in order to convert information between different coordinate systems. A modular approach has been extensively tested during VIAC which has offered a unique chance to face pros and cons of different calibration procedures; data collected during the expedition has also become a reference benchmark for further improvements. © 2012 IEEE.
