Simulation system and method for determining the compass bearing of directing means of a virtual projectile/missile firing device

摘要

A simulation system including at least one virtual projectile/missile firing device associated to a determined position and having a movable director arranged to direct a virtual projectile/missile towards a target and an image capturer arranged to capture at least one image of a scene in front of the director. The simulation system includes a terrain database with the positions of landmarks marked, a processor arranged to process the image of the scene so as to identify at least one landmark of the terrain database in the image and the processor is further arranged to determine a compass bearing of the director based on at least the position of the virtual projectile/missile and the position of the identified at least one landmark.

1. A simulation system, comprising:
at least one virtual projectile/missile firing device associated to a determined geographical position, a movable directing element arranged to direct a virtual projectile/missile from the at least one virtual projectile/missile firing device towards a target, an image capturing unit arranged to capture at least one image of an actual scene in front of the directing element, wherein the image capturing unit is mounted in a fixed and known position in relation to the movable directing element, a terrain database comprising landmarks each associated with a geographical position, and a processing unit arranged to process the image of the scene so as to identify at least one landmark of the terrain database in the image, wherein said processing unit is configured to identify the landmark and determine the geographical position associated with the landmark by correlating topographic data extracted from the image with data of the terrain database, and wherein said processing unit is further arranged to determine a compass bearing of the directing element based on at least the determined geographical position of the virtual projectile/missile firing device and the geographical position associated with the identified at least one landmark.
