Laserskaneerimine ehk 3D mõõdistamine on geodeesia valdkonnas üks uudne osa, kuid järjest igapäevaselt kasutatavaks muutumas, sest laserskaneerimise tulemusena on võimalik luua keskkonnast või objektist väga detailne ruumiline punktipilv. Mobiilne laserskaneerimine on mitmekülgne mõõtmismeetod, mida kasutatakse paljudes rakendustes, näiteks teede seisundi hindamisel. Mobiilse laserskaneerimise tulemusena saadud andmeid on võimalik kasutada erinevatel viisidel, mis kiirendavad ja lihtsustavad mitmeid aeganõudvaid ja kulukaid töid suuremahulistel objektidel.
Käesoleva töö eesmärk on tutvustada mobiilse laserskaneerimise kasutamise võimalusi ja analüüsida nende otstarbekust Tallinna Linnavalitsuse tagasiside põhjal ning selgitada välja Tallinna teede seisukord ning teede seisundi hindamise metoodika. Mobiilse laserskaneerimise võimaluste kasutamine on suunatud Eestis asuvatele teedele ja infrastruktuuride toimimisele ning teede seisundi hindamise olulisusele. Uurimistöö eesmärgi täitmiseks kasutati Geodeesia24 poolt 2023. oktoobris mõõdetud Laagna tee punktipilve mudelit. Punktipilve mudeli põhjal on koostatud Eestis kehtivatele nõuetele vastav Laagna tee maa-ala plaan koos tehnovõrkudega ning kirjeldatud ka teisi erinevaid mudeli kasutamise võimalusi.
Töö tulemusena selgus, et Tallinna linnapildis nähakse mobiilse laserskaneerimise tulevikku enim andmete kogumise ja projekteerimislahenduste väljatöötamise valdkonnas. Tallinna Linnavalitsuse töötajad hindavad oma teadmisi enim Tallinna teede seisundi olukorrast keskmiseks või keskmisest kõrgemaks. Tallinna Linnavalitsuses on mobiilse laserskaneerimise andmete kasutamine juba varasemalt kasutatav või tuttav. Varasem kokkupuude on seotud erinevate pilootprojektide või riigihangete väljatöötamisega.
Antud uurimus on oluline ja samuti on edaspidised uuringud vajalikud, sest mobiilne laserskannerimine on kaasaegne tehnoloogia, mille võimalusi töö autorite arvates laialdaselt ei kasutata või ei teata. Töö autorite arvates on võimalik mitmetele erinevatele aeganõudvatele tööülesannete leida üldkasutatav alternatiiv, mille võimalused on laialdased.
Laser scanning, also known as, 3D surveying, is a new part of the field of geodesy, but it is gradually becoming used daily, because as a result of laser scanning, it is possible to create a very detailed spatial point cloud of the environment or object. Mobile laser scanning is a versatile measurement method used in many applications, such as road condition assessment. The data obtained because of mobile laser scanning can be used in various ways, which speed up and simplify several time-consuming and expensive works on large-scale objects. The purpose of this paper is to introduce the possibilities of using mobile laser scanning and analyze their practicality based on feedback from the Tallinn City Government, and to find out the condition of Tallinn's roads and the methodology for assessing the condition of roads. The use of mobile laser scanning capabilities is aimed at the functioning of roads and infrastructures in Estonia and the importance of assessing the condition of roads. The Laagna road point cloud model measured by Geodesia24 in October 2023 was used to fulfill the purpose of the research. Based on the point cloud model, a land area plan of Laagna road with utility networks has been drawn up in accordance with the requirements in force in Estonia, and other different ways of using the model have also been described. As a result of the work, it became clear that the future of mobile laser scanning in the cityscape of Tallinn is mostly seen in the field of data collection and development of design solutions. Employees of the Tallinn City Government rate their knowledge of the condition of Tallinn's roads as average or above average. In the Tallinn City Government, the use of mobile laser scanning data is already used or familiar. Previous exposure is related to the development of various pilot projects or public procurement. This research is important and future research is also necessary because mobile laser scanning is a modern technology, the possibilities of which, according to the authors of the work, are not widely used or not known. According to the authors of the work, it is possible to find a commonly used alternative for several different time-consuming tasks, which has a wide range of possibilities.
