摘要：

An effective approach to extracting geometric information of scenes from a single uncalibrated image is presented in this paper. Without any prior knowledge of the camera, we describe how to employ cross ratio to compute the length of a line segment on plane surface, while only the length(s) of the certain segment(s) is/are known. Real images of indoor and outdoor scene tests validate our approach.
