Drones, which have long been used in warfare, are now popular not only with professional and amateur filmmakers but also with researchers.

Outdoor image processing is difficult in typical European metropolitan areas due to various obstructions to perspectives such as wires, overhangs, poles, and other parts of a building as well as dynamically changing weather conditions affecting the quality of UAV imagery.<\/p>\n<p>A team of researchers, including Rytis Maskeli\u016bnas from the Kaunas University of Technology (KTU), Department of Multi<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a> Engineering, chose to study the fa\u00e7ades of buildings in Vilnius Old Town and surrounding areas.<\/p>\n<p>&#8220;Vilnius is a very unique place architecturally. The city&#8217;s Old Town is a UNESCO World Heritage Site and is full of buildings that vary in style, from Gothic church spires to state-of-the-art glass structures,&#8221; says Andrius Katkevi\u010dius professor at the Department of Electronic Systems, Vilnius Gediminas Technical University, stressing that this is what motivated them to investigate whether algorithms would be able to work across such a wide range of styles.<\/p>\n<p>Such a challenge, according to Maskeli\u016bnas, requires the use of smart signal processing solutions based on artificial intelligence to detect identify and classify buildings in the overall background of the city.\n<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2023\/artificial-intelligenc-5.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2023\/artificial-intelligenc-5.jpg\" data-sub-html=\"Separation of area contours with a Canny filter with a threshold value of 0.16 when (a) the sun is shining, (b) overcast.

Imagine if suddenly part of the fa\u00e7ade of an old building in the Old Town was glazed or redecorated in some avant-garde manner. A drone flying by would record such a change\u2014perhaps it is illegal construction or urban blight,&#8221; says Darius Plonis, professor at the Department of Electronic Systems, Vilnius Gediminas Technical University.<\/p>\n<p>As the drone flies through the city and photographs building fa\u00e7ades, the data is sent wirelessly to a computing platform that can determine what class of fa\u00e7ade a particular building belongs to.<\/p>\n<p>Maskeli\u016bnas believes that the drone&#8217;s photographs of the fa\u00e7ade could also be used to assess the technical condition of buildings: &#8220;Water penetration through seams, cracks in the decor or structure, discolouration of fa\u00e7ade elements or potentially even dents in the surfaces\u2014all these determine the classification of a building and could potentially allow for a fairly accurate and automated assessment.&#8221;<\/p>\n<p>The Kaunas University of Technology researcher stresses that the parts monitored by the drone can also be analyzed independently of the fa\u00e7ade as a whole, and their durability can be assessed by comparing the changes, both by visual inspection and concerning the building&#8217;s design documentation, construction materials, and the different extent and severity of the damage.\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"An_overcrowded_city_is_a_challenge\"><\/span>An overcrowded city is a challenge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to the researchers, the study aims to detect the boundaries of a building&#8217;s fa\u00e7ade in the face of changing weather and light conditions and to determine its actual style of it based on fa\u00e7ade taxonomy. The complexity of the task depends on the shape of the building&#8217;s fa\u00e7ade, the natural conditions and the urban background behind it.<\/p>\n<p>&#8220;For the algorithm, a congested city is the most difficult task to extract useful information, as buildings in city centers or old towns are very often obscured by various objects such as wires, trees and even festive decorations, and advertisements. Nevertheless, the UAV can collect a detailed, high-quality image of the fa\u00e7ade from all angles,&#8221; the researchers note.<\/p>\n<p>Previously, using rudimentary mathematical models, the researchers could only identify buildings with a simple fa\u00e7ade structure. In addition, the buildings to be classified had to be separated from each other, i.e. not share any common walls or at least be distinguishable stylistically.<\/p>\n<p>According to Maskeli\u016bnas, identifying buildings with a similar fa\u00e7ade structure poses many problems.<\/p>\n<p>&#8220;Distance and environmental factors make it difficult to distinguish the contours of fa\u00e7ade elements, and false contours can be caused by shadows or reflections, as well as camera angle and lens distortion. Simply extracting the correct shape does not guarantee successful further classification,&#8221; says the researcher, emphasizing that these are the reasons why artificial intelligence-based signal processing solutions were used in this study.<\/p>\n<p>Images of the urban landscape captured by drones can also be used for visual landmarks and to identify defects in historic buildings, and urban heritage sites, or for planning urban development.<\/p>\n<p>&#8220;This is a very promising technology for monitoring high-rise buildings and apartment blocks, as it is difficult to see the top from the ground,&#8221; the researchers add.<\/p>\n<p>The research is published in the journal <i>Electronics<\/i>.\n                                                                                                                            <\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n                                                Rytis Maskeli\u016bnas et al, Building Fa\u00e7ade Style Classification from UAV Imagery Using a Pareto-Optimized Deep Learning Network, <i>Electronics<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.3390\/electronics11213450\">DOI: 10.3390\/electronics11213450<\/a><\/p>\n<\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Kaunas University of Technology<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/ktu.edu\/en\"><br \/>\n                                                        <svg><use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/><\/svg><\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Artificial intelligence to help prevent illegal construction (2023, January 16)<br \/>\n                                                retrieved 17 January 2023<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2023-01-artificial-intelligence-illegal.html<\/p>\n<p>                                            This document is subject to copyright.
