Testing 3D laser scanner Trimble SX10 at different distances from the object

Abstract

Rad opisuje osnovne pojmove vezane uz tehnologiju laserskog skeniranja, s naglaskom na karakteristike i primjenu 3D skenera Trimble SX10. Objašnjava se princip rada LiDAR sustava, načine prikupljanja podataka te formiranje oblaka točaka. Detaljnije se analizira utjecaj udaljenosti laserskog skenera od objekta i skeniranja u odnosu na gustoću i točnost dobivenih podataka. Prikazan je pregled skenera različitih dometa te usporedba njihovih tehničkih mogućnosti. Rad uključuje provedbu praktičnog mjerenja na terenu pomoću 3D laserskog skenera Trimble SX10 na definiranim udaljenostima. Prikupljeni podaci obra eni su u softveru za obradu oblaka točaka TBC (Trimble Business Center), a pruža se i analiza rezultata u kontekstu primjena gustoće i preciznosti u odnosu na udaljenosti. Rezultati su prikazani grafički. A zaključci su doneseni na temelju dobivenih podataka i usporedbe s tehničkom dokumentacijom ure aja. Cilj rada je definirati optimalne uvjete za upotrebu skenera u geodetsko-geomatičkoj praksi.The paper describes the basic concepts related to laser scanning technology, with an emphasis on the characteristics and application of the Trimble SX10 3D scanner. The principle of operation of the LiDAR system, the method of data collection and point cloud formation are explained. The influence of the distance of the laser scanner from the object and the scan in relation to te density and accuracy of the obtained data is analyzed in more detail. An overview of scanners with different ranges and a comparison of their tehnical capabilities are presented. The paper includes the implementation of practical field measurements using the Trimble SX10 3D laser scanner at defined distances. The collected dana were processed in the TBC (Trimble Business Center) point cloud processing software, and the results are presented and analyzed in the context of the application of density and accuracy in relation to distances. The results are presented graphically. Conclusions are drawn based on the obtained dana and comparison eith the tehnical documentation of the device. Thea im of the pape ris to define optimal conditions for the use of the scanner in geodetic and geomatic practice
