AUGMENTED REALITY METHOD AND APPARATUS FOR ASSISTING AN OPERATOR TO PERFORM A TASK ON A MOVING OBJECT
First Claim
1. An augmented reality method for assisting an operator to perform a task within a working zone on an object moving along a path intersecting the working zone and according to at least one characteristic of said object, said method being for use with a sensor unit configured to generate data indicative of said object characteristic at a detecting position upstream said working zone, said method comprising the steps of:
- i) generating task instruction data according to said characteristic indicative data;
ii) estimating successive positions of said object as it moves toward and through the working zone to generate object position tracking data;
iii) processing said task instruction data and said object position tracking data to generate object tracking task instruction data; and
iv) projecting light according to said object tracking task instruction data onto said object as it moves through the working zone to provide a visual instruction for the operator about the task to perform on the object.
