METHOD FOR ESTIMATING A UNIFIED PROJECTION MODEL FOR A CAMERA AND APPARATUS PERFORMING THE SAME

摘要

A method for estimating a unified projection model for a camera and an apparatus performing the method are provided. An image captured by the camera is received. A non-metric calibration object is captured in the image. A plurality of feature points associated to the non-metric calibration object on the image is extracted. A camera parameters vector is extracted using the plurality of feature points. An objective function of the camera parameters vector is defined. The unified projection model of the camera is then estimated using the camera parameters vector and the objective function.
