Abstract

The invention provides a method and a device for detecting the target number in a scene. The method comprises the following steps: acquiring a first image of the scene, wherein the first image does not include persons; shooting the scene within a predetermined time bucket to acquire a second image including persons; extracting a foreground image which is the difference zone of the second image and the first image; detecting the second image through a face detection algorithm to obtain at least one face pre-detection zone; when a zone matched with the face pre-detection zone exists in the foreground image, determining the face pre-detection zone as a person target; counting the determined person targets to obtain the target number in the second image. Through the adoption the technical scheme, the target number in the scene can be counted without manual operation, so that the scheme is low in cost; through comparison between the result of the face detection algorithm and the foreground image, the statistical result is high in accuracy.

Description

technical field [0001] The invention relates to the field of image technology, in particular to a method and device for detecting the number of objects in a scene. Background technique [0002] With the continuous improvement of people's living standards, people's cultural life is increasingly rich and active, and more and more people go to theaters, theaters and other occasions to appreciate movies, dramas and other arts. However, due to various reasons, the actual box office of movies and drama theaters cannot be truly reflected, because the national movie box office information system can only display the computer box office part, and there is no way to get an accurate box office at the first time, and the computer system that reports the box office A set is expensive, and some old theaters simply do not have the ability to install it. In addition, the film studios have formed another statistical channel through the statistics of the ticket inspectors of the distribution ...
