Abstract

Prikaz i prezentacija konstrukcijskih rješenja jednostavnija je i fleksibilnija direktno pomoću 3D modela u CAD aplikacijama. Prilikom prezentiranja rješenja manipulacija CAD modelom ima veliki značaj jer upravo manipulacija korisniku omogućuje pogled na CAD model sa svih strana, odnosno korisniku omogućuje pomicanje, rotaciju i skaliranje modela. Manipulacija se najčešće provodi računalnom periferijom, a da bi se korisniku omogućila veća fleksibilnost – da ne mora nužno sjediti ispred računala, uvodi se beskontaktna manipulacija. Beskontaktna manipulacija zasniva se na beskontaktnoj komunikaciji korisnika s računalom, a najčešće se provodi gestama i glasovnim unosom. U ovom diplomskom radu korištena su načela umjetne inteligencije i računalnog vida za izradu aplikacije za beskontaktnu manipulaciju CAD modelom. Aplikacija za manipulaciju CAD modelom koristi geste koje prepoznaje (detektira) i prati, a računalni vid ostvaren je pomoću web kamere. Na početku su definirani zahtjevi koje aplikacija mora ispuniti, zatim je pregledana literatura na temu umjetne inteligencije i računalnog vida, u sklopu koje su definirani osnovni pojmovi i pregledane su slične aplikacije. Nakon pregleda literature dano je idejno rješenje aplikacije, definirane su biblioteke potrebne za izradu koda u programskom jeziku Python, a zatim su definirane geste koje se upotrebljavaju u radu. Rad završava izradom programskog koda aplikacije te testiranjem aplikacije u okruženju CAD aplikacije SolidWorks.

Abstract (english)

Presentation of a design solution directly from a CAD application based on a CAD model is allowing a user to be more flexible. There is no need to prepare images of a CAD model and then be limited by the collected views. CAD model manipulation is allowing a user to see a model from any point of view and also use different operations such as rotation, translation and scaling. Manipulation is mostly provided by the use of a keyboard and mouse. To provide a user with more flexibility so that he doesn't need to sit or stand near a computer while manipulating with CAD model, touchless manipulation is proposed. Touchless manipulation is based on Human-Computer Interaction (HCI) which is mostly provided by the use of gestures or voice commands. To create an application for a touchless CAD model manipulation, in this Master Thesis are implemented principles of Artificial intelligence (AI) and Computer Vision (CV). CV is allowed through a pc web camera. At the beginning of the thesis, there are defined requirements which application need to satisfy. Afterwards, literature on topics of AI and CV is investigated and similar applications are checked. After literature investigation, all required Python dependencies are defined. Furthermore, gestures used for manipulation and auxiliary functions are defined and an application is created. In the end, the application is tested in real-time in the SolidWorks environment.
