Publisher's Synopsis
Excerpt from Preliminary Implementation of a Ratio Image Depth Sensor
The remainder of this introductory section reviews some of the many approaches to the problem of acquiring geometric information from a scene. The second section describes our novel structured light method. The third section describes an elementary implementation of this Ratio Image method which we have used to test the behavior of our theoretical assumptions in practice, and shows a 'depth image' made using this implementation. It also presents the results of some preliminary measurements designed to elucidate the sources of error in the measurements. The fourth and final section discusses factors which limit the resolution of images made with this method.
