Abstract: 

Crowd Behavior Analysis technology of Computer Vision Technology can research on

valuable public urban spaces near the boundary of Urban National Parks，aiming at some problems of urban spaces near the boundary of Urban National Parks which include streets，small squares，street greenbelts and courtyards，such as lack ofviewing effect，low rate of utilization and attraction，inconvenience for activities. Firstly，use Video Surveillance Technology，and found a camera sensor network. Then，recognize tracks using sensor networks through YALMIP toolbox，transfer the tracking problem to integer programming model，and solve the problems through the model. Next，to analyze behavior，to collect tracks，to integrate tracks and to match them by similarity based on the foundation of track recognition and trajectory clustering. Finally，match the activity types with space ranges and develop behavior prototypes，coordinating with judgment of human eyes，ground truth observation and questionnaire investigation. Abstract behavior prototypes to structure prototypes，and then come up with pattern prototypes through the organization of landscape elements. The achievements of the research is expected to obtain space prototypes near the boundary of Urban National Parks.The space prototypes，as the smallest unit urban spaces，can improve urban space layout to be more convenient，compact and complete.
