Mapping in a City Environment Using a Single Hand-Held Digital Camera

In this context this paper proposes a conceptual framework for a mapping process in an attempt to survey city blocks where the only sensory input is a single low-cost digital camera. This proof-of-concept measuring process begins with taking images of at least two known geo-referenced control points and involves taking sequential images as the user walks forward around a city block. Each image is linked to previous images of the same scene taken from a previously occupied location.
