The Generation of Depth Maps via Depth-from-Defocus

This thesis presents a single-image method of generating a high-density, high-accuracy depth map via the evaluation of the edge profiles of a projected structured light pattern. A novel technique of moving the projected pattern during the image capture stage allows the development of a 4-dimensional look-up table. This technique offers a solution to one of the last remaining problems in DfD, that of spatial variance.

It also uses a technique to remove the dependence of original scene reflectance. The final solution generates a depth map of up to 240,000 spatially invariant depth estimates per scene image, with an accuracy of within ± 0.5%, over a depth range of 10 cm. The depth map is generated in a processing time of approximately 14 seconds.

Note: This thesis can now be obtained as a book publication The Generation of Depth Maps via Depth-from-Defocus: An empirical approach to implementing DfD
