Abstract :
The presented demonstrator implements a person counting system using a single overhead sensor and counting the number of people going in and out of an observed area. It is based on a low-power vision sensor, which extracts the contrast of the image in a binary form, implements motion by differencing two successive frames and dispatches the asserted pixels through an address-driven data representation. A lightweight counting people algorithm has been developed, which is based on virtual loop. The demonstrator consists of the vision sensor interfaced with the FPGA and linked to a PC with a graphical interface.
