Abstract. This paper presents two methods to calibrate a photogrammetric-based mobile mapping system.

The paper is organised as follow. The first part presents the problem we are trying to solve, i.e. the calibration of multi-camera head on a mobile mapping system equipped with an Inertial Navigation System (INS). We want to estimate on the one hand the relative pose of images within the head and on the other hand the relative pose between the head and the INS The second part presents the first calibration method which is based on observations of a sub-millimeter accuracy topometric target network. The third part explores a method to determine the calibration on-line, i.e. using the images acquired during the surveys. The final section compare the two methods on an neutral data set and resumes the pros and cons of each method.
