Abstract:

In order to study the human motion model,a limbs movement pattern acquisition system is designed which consists of PCI-1411 video capture card and the digital image processing platform based on LabVIEW machine vision.This research sets up the mathematical model motion of relevant limbs through processed video frames of the limbs movement,and obtains the accurate parameters of limbs movement.The results show that the movement model established by the video capture technology has the advantages of higher accuracy,faster processing speed,less system error,and easy analyzing and processing function over the models based on sensors acquisition technology.
