Abstract: A method for acquiring gait parameters of an individual is disclosed. The method includes capturing calibration images from foot marker placed on feet or shoes of an individual while an individual is standing still, the calibration images are obtained from a camera worn by the individual, capturing subsequent time-varying images from the foot markers while the individual is walking, and comparing the calibration images to the subsequent time-varying images by a processing unit that is coupled to the camera to determine changes between the initial relative image size of the foot markers and the time-varying images of the foot markers as a function of time to analyze gait of the individual.

Abstract translation: 公开了一种用于获取个体的步态参数的方法。 该方法包括：当个体静止时，从放置在个体的脚或鞋上的脚标记捕获校准图像，校准图像从个体穿戴的相机获得，并从脚标记捕获随后的时变图像，而个体 正在步行，并且通过耦合到相机的处理单元将校准图像与随后的时变图像进行比较，以确定脚标记的初始相对图像尺寸和脚标记的时变图像之间的变化，作为 时间的功能来分析个人的步态。
