Abstract
Za potrebe georeferenciranja in analizo kakovosti položaja oblaka točk pri aerolaserskem skeniranju lahko uporabimo oslonilne točke v obliki stožcev. Za ocenjevanje kakovosti geometrije in georeferenciranje oblakov točk aerolaserskega skeniranja na podlagi modelov stožcev, ki bodo služili kot kontrolne talne tarče, je potrebno natančno poznavanje parametrov modelov stožcev. V okviru diplomske naloge smo z elektronskim tahimetrom Leica TCRP1201+R1000 izmerili šest modelov stožcev, izračunali njihove parametre, razliko med vrhi in sredino reflektorja ter odstopanje od projektirane oblike. Vzpostavili smo tudi geodetsko mikromrežo, ki je služila kot testno polje pri opazovanju točk na površini plaščev stožcev. Točke na stožcih smo opazovali s polarno metodo, pri čemer smo uporabili možnost merjenja dolžin brez reflektorja. Za izračun koordinat oblakov točk plaščev stožcev, izračun parametrov stožcev, analizo prileganja oblaka točk izdelanim in projektiranim oblikam modelov stožcev, smo izdelali lastno programsko opremo. V nalogi so predstavljeni rezultati izravnav geodetskih mrež, izračuna parametrov stožcev, adicijskih konstant ter odstopanja oblakov točk od modelov stožcev. Ti rezultati bodo v prihodnje uporabljeni pri raziskovalnem področju analize kakovosti geometrije oblakov točk zračnega laserskega skeniranja z uporabo modelov stožcev.

Title:Cone models geometry calculation and manufacturing quality analysis
Abstract:
For the purpose of georeferencing and quality analysis of the position of the point clouds obtained in aerolaser scanning, cones can be used as ground control targets. To evaluate the quality of geometry and point cloud georeferencing, based on cone models as ground control targets, knowing their shapes and parameters is necessary. As part of graduation thesis we measured six cone models with electronic total station Leica TCRP1201 + R1000, calculated their parameters, distances between cone tops and center of reflector and we determined differences between actual models and designed shapes. We have established a geodetic micronetwork, which was used as a test field for observation points on the surface of the cones. For points observation we used a polar method, distances were measured with reflectorless technique. We developed our own software, which was used for calculations. In graduation thesis we present the results of adjustment of geodetic networks, calculation of cone parameters, addition constant and deviation of point clouds. The results will be used for further analysis which includes quality of point cloud geometry in airborne laser scanning, using cone models.

Keywords:cone model, ground control targets, aerolaser scanning, geodetic micronetwork, cone model parameters, addition constant, quality analysis
