TopCodes service allows to recognize a special code. You can print these codes using the attached topcodes.pdf.

The service gives back the following information :

• Number of the code recognized
• Coordinates of the center of the code (x,y)
• Diameter of the code (which can be used to find distance)
• Angular rotation of the code

​THERE ARE 99 DIFFERENT CODES.

CAMERA SHOULD BE AS PERPENDICULAR AS POSSIBLE TO THE CODE, IN ORDER TO WORK WELL.
