Constrained Multi Camera Calibration For Lane Merge Observation

For the trajectory planning in autonomous driving, the accurate localization of the vehicles is required. Accurate localizations of the ego-vehicle will be provided by the next generation of connected cars using 5G. Until all cars participate in the network, un-connected cars have to be considered as well. These cars are localized via static cameras positioned next to the road. To achieve high accuracy in the vehicle localization, the highly accurate calibration of the cameras is required. Accurately measured landmarks as well as a priori knowledge about the camera configuration are used to develop the proposed constrained multi camera calibration technique. The reprojection error for all cameras is minimized using a differential evolution (DE) optimization strategy. Evaluations on data recorded on a test track show that the proposed calibration technique provides adequate calibration accuracy while the accuracies of reference implementations are insufficient.
