Problems solved by technology

At present, the methods of people flow statistics based on head detection technology mainly include the following types. One is the method of people flow statistics based on image edge detection. The distance between them can be used to judge whether there may be a head target; the accuracy of this method is not high, and the detection speed cannot meet the real-time requirements
The second is the people flow statistics based on the Hough (Hough) transform. The parameter space involved in this method is a three-dimensional space, and the calculation amount is large and the processing is complicated, and the accuracy rate is not high

Embodiment Construction

[0064]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0065] The embodiment of the present invention provides a method and device for counting people flow based on head detection. First, at least one head feature is obtained by performing deep learning on the target detection image of the target area. Due to the process of deep learning, high-level and deep-level abstraction can be obtained. Human head features, which make head detection more effective and convenient. Secondly, recursively analyze the head features to ...

Abstract

The embodiment of the invention provides a visitor flow rate statistics method and device. The method comprises: a target detection image of a target area is obtained; head detection is carried out on the target detection image by using a deep learning method to obtain at least one head feature; a recursive analysis is carried out on the at least one head feature to obtain attribute information of the at least one head feature; and on the basis of the attribute information of the at least one head feature, statistics of the visitor flow rate in the target area is carried out. Therefore, head detection can be realized effectively and conveniently and the accuracy of the visitor flow rate statistics can be improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to the technical field of image processing, and in particular to a method and device for counting people flow. Background technique [0002] With the development of Internet technology, image processing technology has developed rapidly. In the field of image processing, people counting is an important application, and it is also a new field in intelligent video surveillance. Since the shape of the human head (circular shape) is more fixed than that of other parts of the human body, and the possibility of occlusion is less, head detection is often used in people flow statistics. The main task of head detection is to capture the size and position of the human head contour in time through the automatic analysis of the input image. At present, the methods of people flow statistics based on head detection technology mainly include the following types. One is the method of ...
