Camera device and method for reading optical codes

A method of reading optical codes, the method comprising:

• at least one first camera unit that detects image data from a first detection zone and a second camera unit that detects image data from a second detection zone,
• wherein the camera units each locate regions of interest having optical codes in the image data and transmit the image data of the regions of interest to a common controller,
• wherein the common controller combines the image data in regions of interest recorded by more than one camera unit and reads an optical code in the region of interest therefrom,
• and wherein the respective camera units or the common controller converts the camera coordinates into global coordinates by the respective camera units determining a position of a located region of interest in global coordinates or the common controller converting the camera coordinates into global coordinates.

A camera device for reading optical codes, the camera device comprising:

• at least one first camera unit having a first camera controller and a first image sensor for recording image data from a first detection zone, and that has a second camera unit having a second camera controller and a second image sensor for recording image data from a second detection zone that overlaps at least partially with the first detection zone, and that has a common controller,
• wherein the respective camera controller is configured to locate regions of interest having optical codes in the image data and to transmit the image data of the regions of interest to the common controller,
• wherein the common controller is configured to combine the image data in regions of interest recorded by more than one camera unit and to read an optical code in the region of interest therefrom,
• and wherein the respective camera controller is configured to determine a position of a located region of interest in global coordinates and to transmit the global coordinates to the common controller,
• and wherein the respective camera controller transmits the position of a located region of interest in camera coordinates to the common controller and the common controller converts the camera coordinates into global coordinates.
