Development of a universal cell for optical part inspection in a robotic workplace
Cahlík, Radim ; Rajchl, Matej (referee) ; Adámek, Roman (advisor)
Cílem této diplomové práce je vývoj univerzální buňky pro optickou kontrolu včetně softwaru pro detekci vad, který používá metody umělé inteligence. Dalším cílem je integrovat buňku do robotického pracoviště a otestovat ji na rozdílných dílech s různými vadami. První část práce popisuje vývoj konceptu optické buňky a její návrh. Poté pojednává o systému pro optickou kontrolu, počínaje popisem objektivu a kamery a konče analýzou kontrolního softwaru, který pro detekci vad využívá konvoluční neuronovou síť. Další část se zabývá vývojem robotického pracoviště včetně návrhu dvojosého robota a komunikace mezi zařízeními. Nakonec je rozebráno testování na dvou rozdílných dílech s cílem ověřit funkčnost.
Machine vision for the check of moldings
Grepl, Pavel ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
Bachelor's thesis deals with the design of arrangement of an automatic inspection unit for specified products using machine vision. The theoretical part is focused on specification of the inspection system and research in the area of machine vision components, such as cameras, lens and illumination. The practical part consists of multiple possible arrangements of the inspection unit. Solutions of the chosen arrangements, including programming and testing the application using Vision Assistant software. Finally, economic evaluation of the automation of the quality inspection using machine vision has been made.
Noncontact monitoring of dimensional accuracy of large-scale 3D printing
Paulíček, Jiří ; Mendřický, Radomír (referee) ; Koutecký, Tomáš (advisor)
This diploma thesis deals with a design and manufacture of a scanner that is used for online monitoring of a large-scale 3D printing of concrete mixtures. The aim is to design a scanner usable with an active print head designed at VUT. The scanner works on the principle of active laser triangulation, where a laser line is projected on an extruded material immediately behind the nozzle. The projection of the laser line on the extruded materiál is captured by a camera. During the design, FEM analysis was used due to the sizing of the main parts of the scanner depending on the deformations caused by the operating load. Excessive deformations would cause measurement inaccuracies. The height and width are calculated from the image in the MATLAB software. This manufactured scanner was tested during the printing of a real object.
