| Popis: | The author examines different constraints which can be used to find the correspondences between line segments in an image sequence. These constraints are imposed by the continuity of the 3-D motion and also by certain types of motions. The author derives simple equations which relate corresponding tokens in three consecutive images when the 3-D motion is a translation. Next, he describes an algorithm for matching line segments when the motion of the camera is approximately known and presents some experimental results. If a camera moving in a stationary environment is considered, an image motion is related to the location of the corresponding object in space with respect to the instantaneous axis of translation. The author performs a geometrical analysis of this relationship and introduces concepts for this analysis. It is noted that this relationship is useful for tracking objects in the field of view. > |
