【 摘 要 】

In this paper, we present a novel approach to track a line segment in the sequence of images obtained by camera in motion. We use the slope of segment as feature to track. The proposed method is based only on the formalism of the slope of the segment. We use the definition of the projection of points and the relation which exists between the slopes of the segment in various images. The approach developed not needs the calibration of camera or any knowledge about its movements. To resolve the tracking problem, two segments in three images are necessary. Experiment showed feasibility as well as robustness of the algorithm.
