ABSTRACT:
In a method and system for controlling a revolving door that has a plurality of chambers defined by wings of a revolver, at least one imaging sensor is provided for acquiring images of a first area where the plurality of chambers rotatably pass by or through. A drive causes the revolver to rotate in a first direction from a first position where a user can enter a first chamber via the first opening. Images are acquired by the one imaging sensor and signals are acquired from a position sensor that is operative for outputting signals indicative of the angular position of the revolver. Based on the signals acquired from the position sensor, each imaging sensor or its output is disabled and/or each image acquired by each imaging sensor is ignored when each door wing is in field-of-view of the imaging sensor.
