20.500.12556/RUL-139766 Merjenje višine vodne gladine aeriranega toka z lidarjem Measurement of water level in aerated stream with lidar Diplomska naloga obravnava delovanja komercialnega točkovnega LIDAR-a s časovno odvisnim izhodom. Pri skeniranju vodnih teles z LIDAR tehnologijo se pogosto zgodi, da laserski žarki predrejo vodno gladino in ne podajo točne meritve. Zasnovali in izdelali smo merilno postajo z eksperimentalnim valjem, napolnjenim z vodo, ki smo ji z vpihovanjem zraka pri različnih pogojih ustvarjali aerirano vodno gladino. Na postajo smo vgradili LIDAR ter sistem za posnemanje fotografij. Analizirali smo korelacijsko funkcijo, ki jo LIDAR uporablja za pretvorbo podatkov v razdaljo. S primerjavo slik ter rezultatov meritev z LIDAR-om smo pokazali, da večja koncentracija vodnih mehurčkov ustvari dovolj strjeno vodno površino, ki preprečuje laserskemu žarku penetracijo v vodni volumen. The bachelor’s thesis deals with the performance of a commercial point LIDAR with time-dependent output. When scanning water bodies with LIDAR technology, it often happens that laser beams penetrate the water surface and do not give an accurate measurement. We designed and built a measurement station with an experimental cylinder filled with water to which we created an aerated water surface by blowing air under different conditions. The station was equipped with a LIDAR and a photo imaging system. We analyzed the correlation function used by LIDAR to convert the data into the distance. By comparing the images and the LIDAR measurements, we showed that a higher concentration of water bubbles creates a sufficiently hardened water surface to prevent the laser beam from penetrating the water volume.
