The presented stationary apparatus enables to make measurements of qualitative and quantitative pressure distribution under the barefooted human footsole. With a film camera the pressure distribution is recorded on 35 mm black-and-white negative film with 60 pictures/sec during the unrolling of the foot. With a duration of 0.5 sec at a walking speed of 5 km/h the unrolling is recorded by about 30 separate pictures. Besides the illustration of pressure distribution each of the pictures shows: a pressure comparing unit, the side-view of the unrolling foot, the actual recording time in units of 1/100 sec and statements about the test person. Each of the recorded pictures in then scanned by a black-and-white-TV-camera. By means of electronic hardware coloured isobares of the pressure distribution given by the different foot deformities are computed and shown on a colour monitor screen. By strain gages, the three components of the resulting force (weight) are registered synchronously.
所展示的固定装置能够对光脚的人脚底的定性和定量压力分布进行测量。使用胶片相机,在脚部展开过程中,以每秒60张的速度将压力分布记录在35毫米黑白负片上。以5公里/小时的步行速度,展开过程持续0.5秒,大约由30张单独的照片记录。除了压力分布图示外,每张照片还显示:一个压力比较单元、展开脚部的侧视图、以1/100秒为单位的实际记录时间以及关于测试者的说明。然后,每个记录的照片由黑白电视摄像机进行扫描。通过电子硬件,计算出由不同脚部畸形产生的压力分布的彩色等压线,并显示在彩色监视器屏幕上。通过应变片,同步记录合力(重量)的三个分量。
