Abstract
A visual navigation system that rejects reflected images navigates an electrical controllable apparatus such as a mobile robot. The mobile robot is fitted with a minimum of three navigation beacons which emit a light visible to overhead television cameras. The beacons area arranged so as to form a triangle. The shape and the dimension of the triangular pattern are measured and stored in a memory unit within the visual navigation system, and when a reflected image is received it will be characterized by a different angle and thus the vision navigation system is able to distinguish the reflected image from the primary image of the mobile robot.
Claims22
A visual navigation system with a reflection filter for obtaining a spatial position of a manufacturing apparatus, comprising:
- means for obtaining a visual image of the manufacturing apparatus;
- means for filtering of images of the manufacturing apparatus reflected from surfaces in view of the manufacturing apparatus, to obtain a true image thereby;
- and
- means for obtaining the spatial position of the manufacturing apparatus from the true image thereof.
A method for obtaining a spatial position of a manufacturing apparatus, comprising:
- obtaining a visual image of the manufacturing apparatus;
- filtering of images of the manufacturing apparatus reflected from surfaces in view of the manufacturing apparatus, to obtain a true image thereby;
- and
- obtaining the spatial position of the manufacturing apparatus from the true image thereof.
