3D metrology in automation engineering with optical sensors

This video provides a clear and practical introduction to 3D metrology in automation engineering, showing how optical sensors expand the capabilities of traditional tactile measurement systems. It explains how point clouds are generated, how accuracy is evaluated, and why modern optical 3D systems are increasingly used for industrial inspection, robot guidance and inline quality control. You’ll learn how 3D optical metrology works in real applications - from beam labelling and washing‑machine assembly to wood‑processing optimisation - and how point cloud data enables precise measurements, deformation analysis and shape comparison. The video also highlights key considerations such as resolution, noise filtering, measuring volumes and system accuracy, helping you choose the right sensor setup for demanding automation tasks. Topics covered Differences between tactile and optical 3D metrology systems How point clouds are created, processed and used for measurements Real industrial applications using Ensenso 3D sensors Accuracy, resolution and noise considerations in 3D metrology How to adapt optical sensors to different measuring volumes Typical automation use cases for 3D optical systems Video timeline 00:00 - Introduction and agenda 00:42 - Further videos about 3D in machine vision 01:15 - Applications of 3D metrology in automation 04:57 - 3D metrology systems: 2 kind of measuring systems 08:29 - 3D data from tactile and optical measuring system 11:52 - Benefits of the complete surface data 13:20 - Application example of 3D data for complete surface 15:24 - Application: box with different rings 16:44 - Various measurements in a point cloud 18:40 - Accuracy of optical 3d sensors 20:55 - Adapting an optical 3d sensor to your application 22:46 - Adapting different measurement volumes 25:54 - Flexible measurement volume with optical systems 28:28 - Providing point cloud at high framerate 29:44 - Summary Who should watch Ideal for automation engineers, quality assurance specialists, machine builders, system integrators and anyone exploring 3D optical metrology for industrial processes.
