Calculation of 3D Coordinates of a Point on the Basis of a Stereoscopic System

Abstract

Abstract:The solution of three-dimensional (3D) coordinate calculation task for a material point is considered. Two at images (a stereopair) which correspond to the left and to the right viewpoints of a 3D scene are used for this purpose. The stereopair is obtained using two cameras with parallel optical axes. The analytical formulas for calculating 3D coordinates of a material point in the scene were obtained on the basis of analysis of the stereoscopic system optical and geometrical schemes. The detailed presentation of the algorithmic and hardware realization of the given method was discussed with the the practical. The practical module was recommended for the determination of the optical system unknown parameters. The series of experimental investigations were conducted for veri cation of theoretical results. During these experiments the minor inaccuracies were occurred by space distortions in the optical system and by it discrecity. While using the high quality stereoscopic system, the existing calculation inaccuracy enables to apply the given method for the wide range of practical tasks.

Elementary Methods for Generating Three-Dimensional Coordinate Estimation and Image Reconstruction from Series of Two-Dimensional Images

“…SV3DVision [23] is a depth-map generating algorithm used for reconstruction of scenes based on a single-photograph input. e above proposed method uses a singlephotograph input whereas a more calibrated method [24] using parallel axes uses a stereoscopic system. Both these studies focus on identification of near-placed and far-placed objects for depth-map generation, focusing on robotic vision applications [25].…”

Development of Information Models for Increasing the Evaluation Efficiency of Wireless Channel Parameters of 802.11 Standard

“…The effective rate of transmission is an amount of information υ, which is transmitted in the channel for a certain time interval t (2). At the channel layer, depending on the transmission system standard, the information is divided into frames (3), where N f -the number of frames; L f -the length of the frame.…”

“…Analysing the works [3]- [10], one can say that, as a rule, all existing studies were aimed at obtaining a general information model of a wireless channel and determining the software conditions for maximum productivity. However, the actual rate of transmission has a direct dependence on the destabilizing factors in the channel.…”

Geometric Spatial Ability as an Element of Cognitive Learning Process

“…In their article, Berkowitz and Stern (Berkowitz and Stern, 2018) have analyzed the effect of cognitive abilities on academic performance. It was noted that space representation has the grates impact on an ability to construct compared to other cognitive abilities (Mussabayev et al, 2018;Kenshimov et al, 2017).…”
