Upodabljanje velikih količin letalskih podatkov LiDAR : doktorska disertacija

Kuder, Marko

V tem delu opisujemo novejše metode upodabljanja letalskih podatkov LiDAR. Predstavimo tehnike, ki se navadno uporabljajo za izris teh podatkov v obstoječih programskih orodjih, ter njihove prednosti ... in pomanjkljivosti. Novejša alternativa, točkovno upodabljanje z orientiranimi krogi, odpravlja slabosti teh metod in celotne podatke primerno predstavi na različnih ravneh podrobnosti. Algoritme točkovnega upodabljanja v disertaciji podrobno predstavimo, pri čemer izpostavimo glavno pomanjkljivost -- strojno zahtevnost. V nadaljevanju zato opišemo postopek, ki točkovnemu upodabljanju z orientiranimi krogi doda možnost hibridnega izrisa s selektivno pretvorbo v trikotniške mreže, z uporabo katerih lahko pohitrimo delovanje. Postopek predobdelave opredeli dele podatkov, kjer upodabljanje s trikotniškimi mrežami nima običajnih pomanjkljivosti, zato jih je tam mogoče uporabiti kot hitrejšo alternativo točkovnemu upodabljanju ob enakovredni kakovosti. Predstavimo tudi izdelavo tekstur, ob uporabi katerih je mogoče trikotniške mreže poenostaviti brez opaznejše izgube kakovosti in tako dodatno povečati hitrost izrisa. Prostorske zahtevnosti podatkov zaradi dodatka te funkcionalnosti ne povečamo bistveno, saj lahko teksture in trikotniške mreže ustvarimo na zahtevo med običajnim upodabljanjem.
