摘要：
A passive method for estimation of cloud base height using digital images is proposed. The method is based on the property of a perspective change in the angular size of an object moving parallel to the observation plane, depending on the angle of its observation. The estimation of the height of uniformly moving clouds is carried out using a sequence of images from one stationary ground-based camera directed to the zenith. To analyze one-point object, a series of three images is required. And the analysis of an extended two-point object can be carried out using a series of two images.
