Contribution to the analysis of motion behaviour of people in a region using video frames

Abstract

This paper aims to present the evolution of technical software which decodes the behavior of people who walk in the urban environment. It uses and analyzes video frames of a region which are recorded by a stationary, run of the mill, video camera. The software is able to track semi-automatically the motion of targets in a region of interest, and produce the route of the targets in a drawing environment and in a world coordinate system. The photogrammetric Direct Linear Transform (DLT) method with known terrain is used to extract the information from single video frames, simultaneously correcting the non-metric cameras' systematic errors. The Least Square Method is employed to achieve increased accuracy.
