Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail by installing the entrance and exit people counting instrument of the present invention and applying its counting method on the coach door:

[0026] Install a single CCD camera on the ceiling near the door. The CCD camera is connected to the PC through a line. The PC is equipped with an image acquisition card and image recognition algorithm software. The image recognition algorithm software package contains five modules, namely the target background separation module , background reconstruction module, target image post-processing and recognition module, target detection and tracking module, data statistics output module. The direction of the CCD camera lens is perpendicular to the horizontal plane and faces the entrance or exit, or the lens faces the entrance and exit and forms a fixed angle with the horizontal plane. The principle of determining the angle is to ensure ...

Abstract

The invention discloses a method and instrument for counting the people coming in and going out, composed of CCD camera and PC (personal computer), where the CCD camera is fixed on the top of a passageway and connected with the PC by lines, and the PC is installed with picture collection card and picture recognition algorithm software that comprises five modules, i.e. target-background separating module, background reconstructing module, target picture post-processing and recognizing module, target detecting-tracking module and data accounting-outputting module; and the counting method uses the picture collection card to collect the pictures, circularly, real-timely recognizes each collected picture frame, then makes target-background separation, reconstruction, connectivity analysis and false target elimination on the target pictures, after separating the bonded target pictures, compares them with the standard target pictures of human bodies to judge their behavior, and finally counts the people coming in and going out and outputs the count. The invention can be adapted to count the people coming in and going out in various orders.

Description

technical field [0001] The invention relates to an entrance and exit people counter and a method for counting the entrance and exit people by the entrance and exit people counter.
