Badly-fitting shoes are one of the major causes of pain, foot related diseases and injuries of the feet. This article presents a new system for 3D foot-shape measurements which is based on the laser-multiple-line-triangulation principle. The main part of a system is the measuring head comprising a three laser lines projection unit and two cameras, which rotate around the centre of the platform that the customer stands on, and measures both feet simultaneously. The developed software analyzes the different foot dimensions and suggests the most suitable model and size of a shoe from a database to the customer. Validation experiments have been presented to demonstrate the measuring precision of the system. The results show that the standard deviation for all feet dimensions is better than 0.6mm in case of test objectsSlabo prileganje obutve k stopalu je eden glavnih razlogov za bolečine v stopalih ter bolezni in poškodbe stopal. Ustrezne 3-dimezionalne meritve stopala zato omogočajo pridobivanje podatkov za izdelavo ustreznih oblik standardne obutve, prilagajanje obutve obliki stopala individualnega uporabnika, oblikovanje boljšega prileganja obutve pri masovni proizvodnji in določanje kupcu najbolj prilegajočega modela v posamezni trgovini. Slabosti obstoječih sistemov so predvsem v visoki ceni in njihovi kompleksnosti. Zato se večinoma uporabljajo le v raziskovalne in medicinske namene. V članku predstavljamo inovativni merilnik stopal, posebej razvit za merjenje stopal v prodajalnah z obutvijo in specializiranih zdravstvenih ambulantah. Merilnik odlikuje nizka cena izdelave, konstrukcija omogoča visoko stopnjo mobilnosti, poenostavljen in pospešen je postopek merjenjaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
