Disclosed is a method for reading a two-dimensional code (17) by means of a camera (1) used for the three-dimensional optical measurement of an object using triangulation. Said method comprises the steps of placing the camera (1) above the two-dimensional code (17), having a white light source (5) of the camera (1) illuminate the code (17), having the camera (1) capture an image (18) of the code (17), and having an arithmetic unit (6) read data encrypted in the code (17) from the image (18) of the code (17).
