Abstract
An apparatus automatically closes and opens a door in a frame. The door is controlled by a controller providing a safety mode for retaining the door in an open state and, if need be, a door reopening mode if an obstacle blocks the closure of the door. A camera having a vision axis intersecting a plane of the frame, provides an image of a space divided by the plane of the frame. An image analysis unit isolates the regions of interest of an obstacle in the space. A calculator extracts a geometrical characteristic of each region of interest, for classifying the same into a closest category of different safety scenarios of known characteristics, and for outputting, to the controller, a safety signal which activates the safety mode and which is dependent on the evaluation of a safety alarm value calculated by a formula, in accordance with the category.
