Originální abstrakt

This article describes methods, how to calculate a solid angle of some object stored in digital photography. Because a digital photography and geometry of the image depends basically on geometry of the camera lens objective and also on CCD sensor resolution, the geometric calibration of the objective should be performed before use this method. An constants used in this paper was derived from measurement with NIKON Coolpix 990 camera and fisheye lens EC-8. This method can be advantageously used in for example disturbing glare evaluation by some knowing method as UGR or other one.
