Detecting and calibrating unit for reverse vending machine, has imaging sensor for detecting container in working mode and light source that is provided such that calibration pattern is formed in calibration mode at light disk
The detecting and calibrating unit has an imaging sensor (1) for detecting a container (5) in a working mode and a calibration pattern for the calibration of the sensor in a calibration mode. A light module is provided for generating a background illumination during the detection of the container. The light module has a light source (2) and a light disk (3). A control unit is cooperated with an imaging sensor and the light source. The light source is provided such that the calibration pattern is formed in the calibration mode at the light disk.
