Research on precision 3D modeling close-up photography technical
In order to obtain the resolution within 2mm of the geological outcrop section and three-dimensional scene model results within 1cm of the relative accuracy by close-up photography.In this paper,the acquisition technology re-search of high-precision oblique photography and close-up photography on typical mountain cross-section is carried out.A set of targeted technical solution route was explored including precision indicators meaning,performance-matched hardware configuration,software selection for functional adaptation,meet the requirements of the static control net-work,precise measurement of image control points on rock wall sections,outcrop profile fine route planning,application of UAV control measures in complex environment,precision 3D scene modeling for oblique photography and close-up photography,quality control of model precision,the expected goal was achieved successfully.
