Problems solved by technology

[0004] At present, most museums use questionnaires for visitors. This method can only obtain information through written questionnaires or online questionnaires. However, this method of obtaining information is not only time-consuming and labor-intensive, but also the information obtained depends on the respondents. Factors such as herd mentality, misinterpretation of the question by the respondent or non-cooperation of the respondent can easily lead to inaccuracy, which interferes with the analysis of the visitors, and more importantly, it is impossible to understand the truth of the respondent in real time.

Embodiment Construction

[0033] Such as figure 2 The hardware environment for implementing the binocular vision-based crowd flow analysis method of the present invention is: a binocular vision sensor 10 is installed at the booth 20 where exhibits 40 are placed, and the binocular vision sensor 10 is generally installed above the booth 20, and the booth 20 is in the In the set visiting area 50, the binocular vision sensor 10 is used to shoot the scene within the range of its angle of view at the set shooting interval in the set shooting time to obtain a pair of stereoscopic images. In actual implementation, the stereoscopic image The resolution is preferably greater than 640×480 pixels, and the viewing angle range of the binocular vision sensor 10 is different from the set viewing area 50 but the viewing angle range should cover the set viewing area 50 .

[0034] Such as figure 1 and figure 2 As shown, the people flow analysis method based on binocular vision of the present invention comprises the f...

Abstract

The invention discloses a people stream analysis method based on binocular vision. The analysis method comprises steps of stereo image obtaining; image preprocessing; face detection; human body positioning; counting of visitors and visit time, gender identification and age estimation; finishing people stream analysis in a set visit region around an exhibition stand. The analysis method can be applied to all kinds of public exhibition places like museums and related information of visitors in front of all exhibition products in a public exhibition place is acquired and analyzed, so an objective of people stream counting and analysis is achieved; the analysis method is characterized by high real-time performance, high precision and high implementation efficiency; and the method facilitates actually knowing of action characteristics of visitors, and provides a reliable data basis for all kinds of analysis, thereby facilitating improvement of self service quality and level of the public exhibition place.

Description

technical field [0001] The invention relates to a human flow analysis method based on a binocular vision sensor, which is applicable to various public exhibition places such as museums. Background technique [0002] Museums are public welfare institutions that undertake the functions of exhibition, education, research, and entertainment in social and cultural activities. They can enrich the amount of information contained in exhibits and carry the development process of human civilization. Visiting museums can not only enrich knowledge and broaden knowledge, but also relax and delight the body and mind. Therefore, it has become a place for people to study and relax. [0003] With the rapid development of science and technology and modern people's continuous pursuit of spiritual and cultural life, the service quality and level of museums can no longer meet the requirements of the times. What types of exhibits are visitors interested in, what types of exhibits are visitors of...
