Furthermore, authorities are finding a record number of tunnels along the U.S.-Mexico border; therefore, underground tunnel characterization is becoming a high priority for U.S. Homeland Security as well. This thesis investigates the performance of a new image registration technique based on a two camera optical- flow configuration using phase correlation techniques. These techniques differ from other image based navigation methods but present a viable alternative increasing autonomy and answering the tunnel based navigation problem. This research presents an optical flow based image registration technique and validates its use with experimental results on a mobile vehicle. Results reveal that further extension to pose estimation yields accuracy within 1:3 cm.\u003c\/p\u003e","brand":"Biblioscholar","offers":[{"title":"Paperback","offer_id":46862452064407,"sku":"9781288305841","price":5096.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781288305841.webp?v=1769966257","url":"https:\/\/atlanticbooks.com\/products\/optical-flow-based-odometry-for-underground-tunnel-exploration-9781288305841","provider":"Atlantic Books","version":"1.0","type":"link"}
