OpenCV在生物力学微形变控制及测试系统中的应用

Application of OpenCV in Biomechanics Micro-deformation Controlling and Testing System

为测量生物力学实验中的微形变,组建了微形变控制装置,结合OpenCV的视频采集与图像处理功能,搭建了生物力学微形变控制与非接触性测量系统。该系统在跟踪并测量特征点信息的同时,可获得其周围组织的运动情况以供后期处理。使用该系统测量足部标本随受力改变而发生的跖骨间距变化,获得了跖骨微运动相关参数。

To test the micro-deformation in biomechanics experiments,the controlling part is built and based on the camera control and image processing functions of OpenCV,the biomechanics micro deformation control and non-contract test system is built.The system is able to track and test the feature point and get the deformation message of surrounding tissues to post process.Based on the system,the metatarsals spacing of human foot specimens in different loading situations is tested.Micro-deformation parameter of metatarsus is calculated.
