Abstract

The invention discloses people counting method and device for accesses. A shoeprint acquisition plate placed at an access bears shoeprints of a person who passing the access; the shoeprints are compared with shoeprints preset in a time window; if the shoeprints are not found in the time window, a number of people counting in the corresponding direction is added by 1 and the shoeprints are stored for the next step; if the shoeprints are found in the time window, the number of people counting in the corresponding direction is kept unchanged; the shoeprints are then compared with shoeprints stored during a people counting period; if the shoeprints are not found in the people counting period, the number of people counting is added by 1; if the shoeprints are found in the people counting period, the number of people counting is kept unchanged. The people counting method for accesses is applicable to people counting for accesses of open scenes, provides the solution to the problem in recognizing same persons among mutually blocked people, is capable of counting the number of entering and exiting people in the same time, and is well adaptive to environments.
