The invention relates to methods for determining oscillations of high buildings. The method involves shooting at two basis points with a digital imaging camera, processing the resulting stereo pair on a digital photogrammetric station with determination of coordinates of points on the surface of the high-rise building and calculation of its vibrations by those. According to the invention, additionally a second digital imaging camera is used, the cameras are switched on in periodic synchronous shooting mode, and processing of the resulting stereo pair is performed by measuring the coordinates of given points. At that the scale factor is taken into account, and by the difference of distances of points to the vertical axis of the high-rise building its linear and angle deviation are determined, by those judgment on vibrations is made. The technical result: provision of accurate determination of the actual position of high-rise building in a fixed time instant, with obtaining the amplitude of its oscillations in the degree or linear measure, improvement of accuracy of determination of vibrations, reduction of prime cost of the method. |
