System and method for capturing measurement images of an object to be measured

A system for capturing measurement images of a measured object, the system comprising:

• a mobile electronic device, the mobile electronic device comprising:
• a housing;
• a camera integrated into the housing, the camera configured to capture measurement images of a measured object within an observation region of the camera;
• a screen integrated into the housing, the screen configured to display images via emitting light the screen positioned to face the observation region of the camera;
• a control unit integrated into the housing, the control unit configured to activate the screen of the mobile electronic device to successively display several different illumination images of a predefined illumination image sequence, the control unit further configured to activate the camera of the mobile electronic device to capture a measurement image of the measured object synchronously with the displaying of each illumination image of the predefined illumination image sequence;
• wherein the following image characteristics of each illumination image of the predefined illumination image sequence are predefined:
• a spectral composition of the light which is emitted by the screen on displaying the respective illumination image,
• for each colour channel of the screen, a uniform brightness value,
• a screen region which is filled out by the respective illumination image, and
• an arrangement of a screen region which is filled out by the respective illumination image, within the total image area of the screen.
