Ljudje smo tudi zaradi naše zmožnosti čutenja, vida in sluha najbolj dominantna bitja na Zemlji. Poleg izumljanja orodij, ki nam pomagajo videti svet okoli nas, stremimo tudi k visoki točnosti podatkov, ki nam jih ta orodja ponujajo. Z uporabo zvočnih valov smo ustvarili SONAR (angl. Sound Navigation And Ranging), z uporabo radijskih valov RADAR (angl. Radio Detection And Ranging), naslednji logični korak pa je uporaba svetlobe za zaznavanje in merjenje razdalje – LiDAR (angl. Light Detection And Ranging). V začetnih poglavjih je opisana metoda zaznavanja in merjenja razdalje, ki deluje na principu merjenja časa preleta. Predstavljeni so tudi tipi optičnih merilnih sistemov LiDAR, ki so danes pogosteje v uporabi. Nekaj pozornosti je usmerjene tudi v različna področja uporabe sistemov LiDAR. Glavni del je osredotočen na izdelavo izdelka, ki deluje na principu LiDAR optičnega merilnika razdalj v prostoru, predstavljen je proces izrisa tridimenzionalnega (3D) modela izdelka ter komponente, ki jih potrebuje za delovanje. Opisane so tudi določene ključne funkcije programskega dela izdelka, ki omogoča zajem oblike celotnega prostora, v katerem naprava deluje. Delo se zaključi s predstavitvijo ter vizualizacijo rezultatov izdelanega optičnega merilnika LiDAR, izbiro programskih knjižnic za vizualizacijo in odpravljanjem težav z lažnimi meritvami. Poleg zaključnih ugotovitev so navedene tudi možne izboljšave ter optimizacije delovanja. People are the most dominant creatures on Earth, partly due to our ability to feel, see and hear. Besides inventing new tools that help us navigate the world around us, we also strive to achieve a high precision of collected data. By using sound waves, we created SONAR (Sound Navigation And Ranging), with the use of radio waves RADAR (Radio Detection And Ranging), the next logical step is using light for detection and distance measurement – LiDAR (Light Detection And Ranging). Initial chapters describe a method for detection and ranging based on the principle of measuring time of flight. The types of optical measurement systems, that are commonly in use today are also presented. Some attention is also given to fields of use for LiDAR technology. The main part focuses on the development of a product, that works on the principle of a LiDAR optical measuring device, the process of creating a three-dimensional model of the product, and on the additional components that are needed for operation. Certain key functions, that enable the device to capture the surrounding space are also described. This work is concluded with a presentation and visualization of achieved results from the constructed LiDAR system. It is further explained what software libraries are used to execute the visualization, and how elimination of false measurements was done. In addition to final findings, possible improvements, and optimization of performance are also listed. |
