DEVICE FOR DETECTION OF OBSTACLES IN A HORIZONTAL PLANE AND DETECTION METHOD IMPLEMENTING SUCH A DEVICE

摘要

An obstacle detection device fitted to a mobile vehicle able to move parallel to a reference plane, comprises: a first emitter referred to as a horizontal emitter of a first horizontal electromagnetic beam extending in a first virtual plane substantially parallel to the reference plane, a first image sensor able to cover a field intended to intersect with the first virtual plane to form a detection surface, an image analysis means able to determine the presence of an obstacle by detecting the presence of an image on the detection surface. A detection method employing the device is provided.

1. An obstacle detection device fitted to a mobile vehicle having a favored direction of travel in a first direction along an axis X, parallel to a reference plane comprising:
a first emitter referred to as a horizontal emitter of a first horizontal electromagnetic beam extending in a first virtual plane substantially parallel to the reference plane, a first image sensor able to cover a field intended to intersect with the first virtual plane to form a detection surface, an image analysis means able to determine the presence of an obstacle by detecting the presence of an image on the detection surface, wherein the first virtual plane forms an angular sector around the axis X, and wherein the device further comprises:
a second emitter referred to as a horizontal emitter of a second horizontal beam extending in a second virtual plane in a first direction, forming an angular sector about an axis Y perpendicular to the axis X and substantially parallel to the reference plane,a second image sensor able to produce an image of the intersection of the second virtual plane and of the obstacle,a third emitter referred to as a horizontal emitter of a third horizontal beam extending in a third virtual plane in a second direction, the opposite of the first direction, forming an angular sector about the axis Y and substantially parallel to the reference plane,a third image sensor able to produce an image of the intersection of the third virtual plane and of the obstacle.
