基于动量动力学模型的行人关系分析
Analysis of pedestrian relationships based on momentum dynamics model
摘要
Abstract
The pedestrian behavior analysis and the pedestrian relationship study were conducted.In consideration of the status that most of the current contributions in the field of computer vision focus on the classification and identification of target behaviors, while the distinguishment of causal relations between targets are less and the existing theories can only describe the causal relationship between two targets in the field of psychology, a method based on the momentum dynamics model was proposed to recognize the causal relationship between two pedestrians.The method is described below: Firstly, a Cam shift algorithm is used for obtaining the positions of targets in a video.Then, a momentum dynamics model is employed based on the concept of causality to distinguish the causal relationship between two pedestrians.Finally, the causal value is calculated.According to the range of causal value, causation, promotion and impediment, the three kinds of causal relationships between two pedestrians, can be gained.The experimental results show that the proposed method can identify the causal relationship between two pedestrians under the situation of video monitoring.关键词
