Abstract:

The purpose of this research is to clarify the research progress of the theory and technology of pedestrian abnormal behavior recognition in public places. Firstly, with the help of China National Knowledge Infrastructure (CNKI) and the Web of Science (WOS), a broad definition and universal characteristics of abnormal pedestrian behavior in public places were given. The existing research results related to abnormal behaviors were divided into three categories: harmful behaviors, dissociable behaviors and violations. Then, from the perspective of data and technological foundations, the existing abnormal behavior recognition methods were divided into four categories: artificial design, human skeleton, Red Geen Blue(RGB) images and wearable sensors. Secondly, this study sorted out the abnormal behavior datasets of mainstream populations both domestically and internationally, and analyzed the performance of relevant algorithms on the datasets. Finally, the limitations of existing research methods in available datasets and data fusion detection were summarized, and future research directions and optimization suggestions were provided. The results indicate that these four types of abnormal behavior recognition methods have their own advantages and disadvantages. It is necessary to construct a diversified, well-defined and high-quality international benchmark dataset of abnormal behaviors among the crowd. Future research should focus on robust and accurate methods, models, and algorithms for identifying abnormal behaviors, explore multi-dimensional data fusion complementary detection methods, improve the application scenario consistency and adaptability of the theoretical results of abnormal behavior recognition, and eventually enhance the level of public place crowd safety governance.
