Sažetak:
Speedup of the processing algorithm for automated visual quality control of ceramic tiles is presented in this paper. The quality classification of ceramic tiles depends on dimensions and surface features. Presented machine vision quality control algorithm analyzes surface features looking for defects and returns number of found defects. Machine vision system for ceramic tiles is a real time system with hard deadline, processing time limited by production line speed. Image processing is time consuming and it could become too slow. The problem increases with tile dimension, color and relief. One of the solutions to decrease the processing time is the usage of parallel processing. The main idea of this paper is the implementation of CUDA (Compute Unified Device Architecture) technology for image processing in visual control of ceramic tiles. It is new technology of general-purpose computing on the GPU (Graphics Processing Unit) that enables easier development of GPU programs. For the purpose of this paper a simple algorithm was written in C programming language that was implemented in the CPU and the GPU. The processing time results and the speedup are compared between the CPU and the GPU for some examples with several dimensions and surface design.
