A Statistical Analysis Of The Mapping Relationship Between Young People's Footwork Characteristics And Walking Stance

In recent years,the study of gait has mainly focused on the disabled and intelligent robots.With the development of video technology,the public security organs also use videos to detect cases.The purpose of this paper is using video analysis to combine the walking stance in the dynamic(walking posture)analysis and the traditional three-dimensional footprint.In order to find the mapping relationship between the walking attitude and the plane footprint and the three-dimensional footprint.This paper focuses on the related issues such as: 1.The probability of a force mark and a pick mark in a three-dimensional footprint.2.For the acquisition of video processing to obtain static pictures,through the identification of key points to the arm,torso and head posture to define,and then determine the ultimate type of walking stance.3.We should count the length of the plane footprint characteristics of the value,thus corresponding to their walking posture.The experimental results show that: 1.In the 300-person collection object,there are 223 of people's three-dimensional footprint which exists force marks,the stability of the acquisition of force marks is 61,and the proportion of the total number is 20.33%;there are 146 of the threedimensional footprint which exists pick marks,the stability of the acquisition of pick marks is48,the proportion of the total number is 16 %.2.When the three-dimensional footprint exists force marks,the probability of the arm is in the state of swinging back and forth,the normal torso and the head in the upward state is the highest which is 24.84%.When there is a pick mark in the three-dimensional footprint,the probability of the arm is in a state of internal buckle,the normal torso,and the head is in the flat view and upward is highest which is23.1%.3.In the plane footprint,the step takes short step length,the arm is in the state of swinging back and forth,the torso is normal and the head is in the downward is highest,which is 22.2%.When the step takes middle step length and long step length,the probability of the arm is in front of the body to shake,the normal torso and the head in the flat view of is highest which is 17.55%and 13.21%.When the step takes the wide step,the probability of the arm is in the state of swinging back and force,the normal torso and the head is in the flat view as well as the rear torso and the head is in flat view is highest,which is 16.43%.When the step takes middle step and narrow step,the probability of the arm is in front of the body to shake,the normal torso and the head in flat view is highest,which is 18.62%.When the step angle takes big outreach,there is only one situation,that is,the arm in front of the swing state,the normal torso and the head in the flat view,in this case the object amount of 1 people,so the probability is 0.33%.When the angle takes middle outreach,the probability of the arm is in the state of swing back and forth,the normal torso and the head in the downward is highest,which is15.24%.when the step angletakes small outreach and straight outreach,the probability of the arm is in front of the swing state,the normal torso and the head in the in the upward is highest,which is18.72%.When the step angle takes a toe-in walking,the probability of the arm is in front of the body of the swing state,the torso forward and head in the upward is highest,which is 14.29%;the probability of the arm is in the state of swing back and force,the normal torso,and head in the downward and the flat view is the same and highest,which is 14.29%.
