Summer Research Stay:
3D surface imaging by fringe projection
This is a short theoretical and practical course for undergraduate students with interest in opto-digital image processing systems for three-dimensional surface imaging (3D scanning). This course provides elementary topics on the digital fringe projection method for optical measurement of 3D objects. This short course can be useful as an introduction to computer vision in graduate studies.
