- Аннотация: For the reconstruction of the parameters of clouds a method was developed based on taking pictures of the sky by a pair of digital photocameras and subsequent processing of the obtained sequence of stereo frames by a method of the morphological analysis of images. The report describes a mathematical model of measurements, poses and solves the problem of calibration of direction of sight of the cameras, describes methods of combining the image fragments by morphological method. The problem of estimating the cloud height and speed of their movement is formulated and solved. The examples of such evaluations from real photos are analyzed and validated by the way of comparing with the results of measurement by laser rangefinder.
