The present invention concerns a method and a system for controlling and monitoring a point of sale, said point of sale having an opening (A), said method and system controlling the potential customers that pass through said opening (A) of said point of sale. Particularly, the system comprises a passage sensor (2), adapted to be disposed in the proximity of said opening (A) for generating a passage signal (Sp) when a person (P) passes through said opening (A), imaging means (5) adapted to be disposed in the proximity of said opening (A) for acquiring an image (6) of at least one person (P) that passes through said opening (A) and connection and control means, for connecting said passage sensor (2) with said imaging means (5) so that, upon generation of said passage signal (Sp), said imaging means (5) acquire the image of said person (P) that is passing through said opening (A). |

1. A method for controlling and monitoring a point of sale, said point of sale having an opening (A), said method controlling the potential customers that pass through said opening (A) of said point of sale and comprising the steps of:
(a) providing a passage sensor (2o, 2i) that generates a passage signal (Sp, Spi, Spo) when at least one person (P, Pi, Po) passes through said opening (A), said passage sensor (2o, 2i) being disposed at the sides of said opening (A) so that said generated passage signal (Sp, Spi, Spo) is directed sideward toward the person (P) entering or leaving said opening (A) (b) triggering imaging means (5) through said passage signal (Sp, Spi, Spo) to acquire the image (6) of said person (Pi, Po); (c) comparing said image (6) of said person (P, Pi, Po) with one or more images (8) provided by a data source (9), in order to obtain the counting of said person (Pi, Po) automatically; said comparing step further comprising a correcting step that prevents any further passages through said opening (A) from being counted, said correcting step preventing a counter (C, Ci, Co) from being incremented if the interval of the time elapsed from the last increment is shorter than a minimum predetermined interval, said correcting step using automatic recognition means in order to provide a value of said person (Pi, Po) that passes through the opening (A) as a potential customer. |
