Patent

CA 2642591

The invention relates to a method of teleoperating an unmanned ground vehicle (10) comprising a first drive unit (1), a second drive unit (2) and a pan camera (4), arranged in front of or behind the nominal centre of rotation (z) of the vehicle. In the method, the operator (8) controls the translation and rotation of the camera, and thus his field of vision, relative to a camera-fixed coordinate system, and the movement of the vehicle is calculated to perform this camera movement. Consequently, the operator can in most cases ignore the vehicle dynamics and experience the feeling of controlling a floating camera. The invention also concerns an unmanned ground vehicle with a control unit which performs the method.

L'invention concerne un procédé de télécommande d'un véhicule terrestre non habité (10) comprenant un premier module de propulsion (2), un deuxième module de propulsion (2) et une caméra panoramique (4), montée à l'avant ou à l'arrière du centre de rotation nominal (z) du véhicule. Selon le procédé de l'invention, un opérateur (8) commande le mouvement en translation et en rotation de la caméra, et donc son champ de vision, dans un système de coordonnées fixe par rapport à la caméra, et le mouvement du véhicule est calculé de façon à suivre le mouvement de la caméra. L'opérateur s'affranchit ainsi de la dynamique du véhicule et a donc l'impression de commander une caméra flottante. L'invention concerne également un véhicule terrestre non habité équipé d'un module de commande mettant en AEuvre ledit procédé.
