Linear or 1D cameras are used in several areas such as industrial inspection and satellite imagery.Since 1D cameras consist of a linear sensor, a motion (usually perpendicular to the sensororientation) is performed in order to acquire a full image.  In this paper, we present a novellinear method to estimate the intrinsic and extrinsic parameters of a 1D camera using a planarobject. As opposed to traditional calibration scheme based on 3D-2D correspondences of landmarks,our method uses homographies induced by the images of a planar object. The proposed algorithm islinear, simple and produces good results as shown by our experiments.
