In simpler terms, it involves capturing images and stitching them together to create a digital model of the physical world.<\/p>\n\n\n\n<p>Think of it like assembling a jigsaw puzzle, where each captured image serves as a puzzle piece that contributes to the whole. The technique can be used to create 2D or 3D models which are so incredibly precise that exact measurements and dimensions can be extracted from it, making it invaluable in many industries, including the railway.<\/p>\n\n\n\n<p>Drones, equipped with cutting-edge photogrammetry technology, deliver huge benefits to the rail industry. These unmanned aerial vehicles (UAVs) provide a fresh perspective to maintenance engineers conducting visual inspections and provide a provide all stakeholders with a range of new tools to accurately collect critical track data efficiently and safely.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Enhanced Surveying<\/h2>\n\n\n\n<p>Traditional rail surveying methods involve manual measurements, ground-based equipment, time-consuming processes and undoubtedly a railway \u201cpossession\u201d.<\/p>\n\n\n\n<p>Whilst these solutions are sometimes the \u201conly fit\u201d, drones change the game by capturing high-resolution aerial imagery without the need to interrupt rail services.<\/p>\n\n\n\n<p>The benefits of UAV include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Speed:<\/strong>\u00a0Faster access to site is probable given that a possession is not required.
