Curriculum

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.

Content:

  1. Welcome
  2. Linear algebra
  3. Homogeneous coordinates
  4. Parallel coordinates
  5. Hough transform
  6. Square-radial checkerboard
  7. Phase demodulation
  8. Triangulation
  9. Fringe projection systems
  10. Calibration
