20.500.12556/DKUM-77753 Analiza napak pri 3D tiskanju hiš s postopki računalniškega vida diplomsko delo Analyzing errors in 3D house printing by computer vision procedures V okviru tega diplomskega dela smo se ukvarjali z analizo in proučevanjem napak, ki nastanejo v širini betonskih slojev pri 3D tiskanju hiš. Zaradi gostote materiala, vodo-cementnega faktorja, temperature in hitrosti nanašanja materiala se sloji neenakomerno nanašajo drug na drugega. Izdelali smo strojno-programski sistem s katerim izboljšamo natančnost 3D tiskanja. Razvili in implementirali smo algoritem za prepoznavo in analiziranje napak pri 3D tiskanju hiš ter android aplikacijo, ki ta algoritem uporablja. Za prepoznavanje napak smo uporabili tehnike računalniškega vida in se opirali na vizualne informacije, pridobljene s klasičnimi kamerami RGB. Rezultate smo analizirali s pomočjo predpripravljenih posnetkov tiskanja zidu v različnih pogojih. Dobljene rezultate smo primerjali z želeno vrednostjo širine sloja, izmerjena odstopanja pa smo v povratni zanki uporabili za korigiranje 3D tiskanja. Z našo rešitvijo bo gradnja oziroma "tiskanje" hiš kvalitetnejše in hitrejše, saj ne bo nepotrebnih zastojev pri ponovni obdelavi napačno izdelanega zidu. Poraba materiala bo manjša, zid pa bo bolj gladek. The present diploma work deals with identifying and analysing errors in the width of concrete layers in 3D house printing. Due to the density of material, water-cement factor, temperature and the rate of application of the material, the layers are applied to each other unevenly. Therefore, an algorithm for identifying errors in the 3D house printing, as well as an Android application, using the algorithm were made and implemented. Computer-vision techniques for identifying errors were used and visual information, obtained by classic RGB cameras, was relied on. The results were analysed using pre-prepared videos of wall printing in different conditions. They were compared to the desired value of the layer width, while the measured deviations were used in the feedback loop for 3D error correction. Our solution should enable better quality and faster construction or 'house printing', as there will be no unnecessary delays in the reprocessing of incorrectly made walls. In addition, the material consumption should be lower and the walls smoother. 3D tisk računalniški vid linijski laser kamera 3D print computer vision line laser camera true true false [M.
