Abstract

The present invention relates to a system and method for the imaging of surfaces of box like objects conveyed along a path. The objects are conveyed past at least one camera which is positioned at an angle to the object's surface. The at least one camera comprises a sensor array and zoom objective, the latter controlled by a control mechanism. The present system further comprises a control unit and at least one sensor. The sensor detects the location and velocity of an object. The data is conveyed to the control unit which further communicates with the control mechanism. The control unit causes the control mechanism to adjust the zoom on the objected so as to stay in constant focus with a passing surface of an object passing through the field of view of the at least one camera. After an object has passed through the field of view, the object is made to return to a home position.

Dependent claims

a system for generating an object surface image of an object being conveyed along a path, comprising:

at least one camera, positioned at an angle to said surface, said at least one camera comprising a sensor array, control mechanism, and zoom objective, whose focus is adjustably controllable by said control mechanism;
at least one sensor positioned along said path for determining location and velocity of said object with respect to said path and said at least one camera;
and
a control unit in electrical communication with said control mechanism and sensor such that said control unit causes said zoom objective to focus and adjust to remain in focus with said surface as said object moves through said at least one camera's field of view.
