Abstract
This paper presents a calibration method of an omnidirectional stereo camera (ODSC) for the purpose of long distance measurement. Existing calibration methods can be used for calibration of an ODSC, but they may be applicable either to calibration of the ODSC with a small baseline or to individual calibration of its two cameras independently. In practice, it is difficult to calibrate the ODSC with a large baseline. A calibration test pattern, which is simultaneously captured by the two cameras of an ODSC system, appears very small in at least one of the cameras. Nevertheless, the baseline should be large enough for long distance measurement to ensure consistency of the estimated distance. In this paper, therefore, we propose a calibration method of the ODSC with a large baseline and verify its feasibility by presenting the experimental results of its distance estimation.
