Abstract
A calibration method for linking spherical coordinates to texture coordinates is provided. The method comprises: installing a plurality of lamps forming a horizontal semicircle arc and a rotation equipment located at its circle center; mounting a N-lens camera on the rotation equipment; causing the N-lens camera to spin about a spin axis passing through two ends of the horizontal semicircle arc and capture a plurality of lens images for different spin angles by the rotation equipment; and, determining longitude and latitude coordinates of a plurality of calibration points according to the different spin angles and the texture coordinates of the calibration points in the lens images to create a link between the spherical coordinates and the texture coordinates. Different positions of the lamps respectively represent different latitudes and different spin angles respectively represent different longitudes. Heights of the camera and the lamps are the same.
