The Crowd Behavior Prototype Study Of Urban Street Pedestrian Space Based On Computer Vision Technology

According to the current situation of city,this paperclarifies the relationship of space-behavior from a brand new perspective.With Computer Vision Technology working on crowd behavior trajectory identification,extraction and behavior analysis,sum up the street elements and scale space and various types of behaviorin order to improve the quality of public space of city through intelligent and accurate design.Street pedestrian space is one of the most important type of space in daily life and academic research.This paper tries to clarify the conception of street and define the research scope of the street pedestrian space.In the process of application of computer vision technology into the public space of the city,the first step is to find a rational place for collecting video data;then,recognize and extract the trajectory by the method of computer vision technology;finally,the accuracy of the test data of the video frame based on human subjective judgment and field observation and questionnaire,appropriate modification,matching activity type and scope.The behavior prototype is the process of generating a model of relationship between crowd behavior and space.That is,spaceforms and scales,space elements and sizes,and specific performances.The final results of the paper can be summarized as follows: first,extend and redefine the concept and connotation of streets,and clarify the studying scope of street pedestrian spaces;second,apply computer vision technology into urban public spaces firstly,and make a complete process of how to use and output trajectory data;finally,from the combination of theory and practice and the combination of subjective and objective aspect,the use of crowd behavior trajectory analysis shows that the computer vision technology,combined with the element type,element size and spatial scale and spatial forms of information,type of induction and deduction of city street walking space behavior prototype,promote the city public space precision and intelligent design.
