  • Secure method and system of video detection for automatically controlling a mechanical system such as a moving staircase or a travelator
    Patent number: 6606538
    Abstract: A method for detecting persons or objects in a detection zone covering a mechanical system that is to be controlled as a function of propel or objects being detected at present in the detection zone an initialization phase consisting in checking the hardware and software elements of a monitoring processor coupled to a control device for controlling the mechanical system; a processing loop comprises for active camera connected to the processor and covering the detection zone: acquiring and processing an image supplied by the camera in order to generate detection data and determine which commands to apply to the control device; and checking both the image quality and the position of the camera relative to the detection zone; and a phase in which the control device is controlled using commands determined in the processing loop and as a function of any faults detected while carrying out the checks.
