Embodiment Construction

[0040] A method and device for counting pedestrians based on multi-camera monitoring provided by an embodiment of the present invention will be exemplarily described below with reference to the accompanying drawings.

[0041] On the one hand, see figure 1 , a method for counting pedestrians based on multi-camera monitoring provided by an embodiment of the present invention is applied to a scene including at least a first camera and a second camera, and the method includes:

[0042] 101: Obtain an overlapping area between the first image captured by the first camera at the first moment and the second image captured by the second camera at the first moment;

[0043]Exemplarily, the method for counting pedestrians based on multi-camera monitoring provided by the embodiment of the present invention can be applied to the scene where at least two cameras are set and the monitoring areas of the at least two cameras overlap. . The overlapping area of ​​the monitoring areas of the tw...

Abstract

The embodiment of the invention discloses a pedestrian counting method and device based on monitoring of multiple cameras and relates to the field of image processing. The pedestrian counting method and device are applied to a scene which at least includes the first camera and the second camera and are used for counting pedestrians in the large scene provided with the multiple cameras. The pedestrian counting method comprises the steps that the overlap region of a first image shot by the first camera at a first moment and a second image shot by the second camera at the first moment is obtained; a first number of the pedestrians in the first image, a second number of the pedestrians in the second image and a third number of the pedestrians in the overlap region are obtained; the total number is obtained according to the first number, the second number and the third number.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for counting pedestrians based on multi-camera monitoring. Background technique [0002] Large-scale public places are generally installed with cameras. Since large-scale public places have the characteristics of large areas, and the monitoring area of ​​a camera is limited, multiple cameras need to be installed in order to comprehensively monitor large-scale public places. Monitoring areas of different cameras may overlap to a certain extent, and the overlapping area is called an overlapping area. At present, the counting of pedestrians in the monitoring area of ​​a single camera can be realized by combining the pedestrian outline information with the ensemble algorithm; the counting of pedestrians in the non-overlapping area of ​​multiple cameras can also be realized by combining the appearance information of pedestrians and the monitoring area restriction in...
