“…Актуальным направлением развития обзорных систем технического зрения (СТЗ) являются системы с распределённой апертурой (РА). Такие СТЗ формируют панорамное фото-или видеоизображение с широким полем зрения [1,2] по информации от нескольких пространственно разнесённых камер, т.е. являются альтернативой применению обзорных СТЗ с механическим перемещением линии визирования (ЛВ).…”

We derive analytical expressions for calculating the number of elementary computational operations required to generate several personal regions of interest in a panoramic computer-vision distributed-aperture system using two alternative strategies: strategy 1 involves acquisition of a complete panoramic frame, followed by the selection of personal regions of interest, while with strategy 2 the region of interest is directly formed for each user. The parameters of analytical expressions include the number of cameras in the distributed system, the number of users, and the resolution of panorama and user frames. The formulas obtained for the given parameters make it possible to determine a strategy that would be optimal in terms of a criterion of the minimum number of elementary computational operations for generating multiple personal regions of interest. The region of interest is generated using only a priori information about the internal and external camera parameters, obtained as a result of their photogrammetric calibration with a universal test object, and does not take into account information about scene correspondences at the boundaries of intersecting fields of view.

The paper is devoted to the problem of increasing the adequacy of perception of the environment by the mobile robot operator using remote control. A variant of a real-time surround-view system for mobile robot based on the multiple cameras with fisheye lenses and overlapping fields of view is proposed. A prototype of the circular view system has been developed. In this paper, the key features of the architecture and software of the surround-view system are considered. The algorithms for determining the internal parameters of cameras and distortion correction are researched. New models for describing the distortions of wide-angle and fisheye lens are used. Algorithms for finding the external parameters of cameras, as well as homography matrices using invariant descriptors, are implemented. Static homography matrices are used during stitching images into panorama. Various image-stitching techniques based on the overlapped images region blending are investigated and implemented. The methods of projective geometry and augmented reality were studied to obtain a perspective third-person view. A surface variant for projecting panorama of a surround view is proposed. For the implementation of the software selected cross-platform game engine "Unity". Directions for further research are identified.
