Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts (2019)
Conference Proceeding
Leach, R. K., Shaheen, A., Piano, S., Sims-Waterhouse, D., & Bointon, P. (2019). Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts

Digital fringe projection is a non-contact method that is widely used for the dimensional characterisation of complex manufactured parts. However, single camera-projector fringe projection systems struggle to acquire the full three-dimensional point...

Modelling Fringe Projection Based on Linear Systems Theory and Geometric Transformation (2019)
Conference Proceeding
Gayton, G., Su, R., & Leach, R. (2019). Modelling Fringe Projection Based on Linear Systems Theory and Geometric Transformation

Fringe projection measurement techniques offer fast, non-contact measurements of the surface form of manufactured parts at relatively low cost. Recent advances in fringe projection have reduced measurement errors from effects such as multiple surface...
