Inspection of surfaces for maintenance tasks

Task

A robot-assisted inspection system has been developed for the routine inspection of industrial plant surfaces. This system carries a camera and is designed to automatically detect damage based on images of the surfaces.

Solution approach

• Design of the image capture system, including lighting, taking into account installation space requirements
• Development of an algorithm for image capture and generation of high dynamic range (HDR) images
• Algorithm for 3D reconstruction of surfaces from structured light projection images
• Recognition of various surface features in the images
• Parameter optimisation for the system using test images

Result

The image shows the 3D reconstruction of the surface.
