3d Cross-sectional Shape Measurement of the Foot While Walking

چکیده
PRINCIPLE Most of the existing 3D shape measurement systems use laser scanning[2], and requires a time (several seconds, typically) for measurement. The principle of laser scanning measurement is triangulation between camera and laser projector. In the field of computer vision, 3D shape of the target object is reconstructed from multiple images using triangulation between multiple cameras (stereo matching)[1]. Theoretically, this method can measure an object as accurate as the laser scanning. Actually, it could not because of difficulties in preprocess calibration and in finding accurate matching points in multiple images

A method to obtain 3D foot shape deformation during the gait cycle
Developed anthropometric measurement systems for the foot are static. However, important changes occur in the 3D shape of the foot during walking. This study deals with computer vision techniques to obtain the 3D foot shape at different step moments during the gait cycle. The foot shape evolution is estimated by comparing the 3D reconstruction of the foot surface at different gait steps. This m...
متن کاملComparison of Foot Pressure Variables in Blind and Healthy Participants with Open and Closed Eyes While Walking
Introduction: Measurement of foot pressure variables can be used to assess the loads to which the human body is subjected in normal activities, like walking, or in more demanding situations such as sports. The purpose of this study was to compare the foot pressure variables in blind and healthy individuals with open and closed eyes during walking. Methods: The present study was a quasi-experim...
متن کاملEffect of Textured Foot Orthoses on the Ground Reaction Force Components in the Older Adults During Walking
Introduction: With aging, the pattern of walking is altered, and the person’s ability to walk will be decreased. Also, with the beginning of the aging process, the coordination of the postural control system was disturbed and lead to an unstable condition. A small biomechanical change in the lower limb is significant on postural control. The use of textured foot orthoses leads to improved effic...
متن کاملKinematics of Hip, Knee and Ankle During Cross- Slope Walking
Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking. Methods: This is a quasi-experimental study...
متن کاملMeasurement of Walking Gait for 3d Passive Dynamic Biped Walker
Passive dynamic bipedal walking (PDW) is an attractive topic not only for robotics field but also the other scientific fields, i.e. physics and biology. In order to clarify its mechanism of walking, many researchers have developed various PDW machines. We also have developed several 3D PDW with flat feet and ankle springs. However there are no researches on the measurement of 3-D PDW gait, whic...
