Paper Abstract

In this paper, we present some results from a study in progress on methods for the measurement of the length of a robber in a surveillance video image. A calibration tool was constructed for the calibration of the camera. Standard procedures for computing the lens distortion, image projection parameters and the length of the robber have been implemented in Mathematika. These procedures are based on the use of pixel coordinates of markers on the calibration tool, the robber's head (and, optionally, his feet) and an estimation of his position in the coordinate system that is defined by the calibration tool.
