The article is devoted to the problem of 3D reconstruction of objects in dynamic scenes by stereo images. When performing any complex tasks by autonomous robots (repair work, inspection of the seabed), there is a need to simultaneously restore the trajectory of the autonomous robot and build a 3D model of the environment using video information. Data on the trajectories of robots and information about the environment are necessary for specialists to further correct drone operation and track the progress of work performed. Сurrently existing object identification solutions help to restore the geometry of dynamic objects with imposed restrictions that prevent from reconstructing the entire scene with the necessary accuracy. Also, the existing methods do not involve detailed visualization of the entire 3D scene using previously unknown point data and do not include the restoration of invisible parts of object surfaces. An approach to solving the problem of identification and 3D reconstruction of objects based on video information in relation to dynamic scenes is proposed. The basis of the software system implementing the proposed algorithmic and architectural solutions is described. Data on model scenes and features of scene objects are given. The results of computational experiments with virtual scenes are discussed. The regularities discovered as a result of tests affecting the accuracy of model reconstruction are considered.
