20.500.12556/DKUM-91521 Simulating and verifying a 2D/3D laser line sensor measurement algorithm on CAD models and real objects The increasing adoption of 2D/3D laser line sensors in industrial and research applications necessitates accurate and efficient simulation tools for tasks such as surface inspection, dimensional verification, and quality control. This paper presents a novel algorithm developed in MATLAB for simulating the measurements of any 2D/3D laser line sensor on STL CAD models. The algorithm uses a modified fast-ray triangular intersection method, addressing challenges such as overlapping triangles in assembly models and incorporating sensor resolution to ensure realistic simulations. Quantitative analysis shows a significant reduction in computation time, enhancing the practical utility of the algorithm. The simulation results exhibit a mean deviation of 0.42 mm when compared to real-world measurements. Notably, the algorithm effectively handles complex geometric features, such as holes and grooves, and offers flexibility in generating point cloud data in both local and global coordinate systems. This work not only reduces the need for physical prototyping, thereby contributing to sustainability, but also supports AI training by generating accurate synthetic data. Future work should aim to further optimize the simulation speed and explore noise modeling to enhance the realism of simulated measurements. 2D/3D laser line sensor profilometry simulation point cloud measurement generation STL Matlab 2D/3D laserski linijski senzorji profilometrija simulacije oblak točk ustvarjanje meritev true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/1424-8220/24/22/7396 Članek v reviji 2025-01-10 15:12:05 2025-01-10 15:12:05 2025-01-11 03:10:39 0000-00-00 00:00:00 2024 0 0 16 str. iss. 22, [article no.] 7396 Vol. 24 Nov. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-11-07 2024-11-18 2024-11-20 004.946 219947267 10.3390/s24227396 1424-8220 sensors-24-07396_(1).pdf sensors-24-07396_(1).pdf 1 F9548BC0F6491916EA560A94FF15470B 106a3dbd3bc0d3312a2e981819407c0dbce3d09aa80b53dbde470cd78dc48003 18646891-cf5d-11ef-8532-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187743 https://www.mdpi.com/1424-8220/24/22/7396 0 1ee46667-cf5d-11ef-8532-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=187744 Fakulteta za strojništvo 0 0 0
