How 3D machine vision is shaping the future of automation?

3D vision and robotics

This video provides a clear and comprehensive introduction to 3D machine vision, explaining why 3D sensing matters and how modern technologies are transforming industrial automation. It outlines the motivations behind using 3D data, the evolution of sensing methods, and the key advantages of 3D over traditional 2D approaches.

You’ll learn about major 3D sensing technologies - including laser triangulation, structured light, stereo vision, and time‑of‑flight - and see how they are applied in real‑world scenarios. The presentation also highlights current developments, data formats such as height maps and point clouds, and the importance of calibration and advanced algorithms. By the end, you’ll have a solid understanding of how 3D vision supports tasks such as quality inspection, robot guidance, logistics, and operation in harsh environments.
