| Abstract: | In this paper,we study the splicing method of tunnel layout map based on FAST feature detection and FLANN feature point matching algorithm,mainly to solve the technical problem of full-frame splicing in the current tunnel image splicing.This article analyzes the two sets of tunnel lining images obtained by the tunnel inspection vehicle in a tunnel.Each set of data contains a certain amount of half-frame tunnel stitching that is triggered by multiple cameras at equal distances and shot simultaneously at the same time.Data,detailed analysis and research on the tunnel's full-frame splicing technology,and proposed effective solutions,which can quickly and accurately splice the tunnel layout to meet the needs of tunnel maintenance. |
