Validation of Calibration Method for Fish-eye Lens using Equiangular Markers : ∼ Aiming for Remote Car Driving ∼

Remote car control requires images of the area around the vehicle to be transmitted to the remote operator. Fish-eye cameras are often used to acquire full-dome images because of their wide viewing angle. Especially, the fish-eye lens of the equidistant projection model is suitable for developing the equirectangular cylindrical view image used in VR. However, inexpensive mass-productive fish-eye lenses raises projection errors due to lens distortion. It is necessary to project to ideal angle by correction method. Therefore, we have proposed a simple and tiny method for estimating and calibrating lens distortion using equiangular markers in a small equipment. In this paper, we evaluate the effectiveness of the proposed method by reprojecting the distorted image as an equidistant projection method using the estimated distortion parameters.
