摘要
目的在不干扰目标设备的条件下提出一种基于视频图像处理的技术方案,从而实现肌电生物反馈仪实时视觉反馈状态信息的数据提取。方法在不对原装备作任何改动的情况下通过视频图像实时采集,对每一帧图像中肌电生物反馈仪放松信号灯的点亮位置进行目标自动识别及动态跟踪,完成放松状态反馈信息数据的采集。结果该方案用于识别并跟踪肌电生物反馈仪中视觉反馈灯点亮位置的准确率达到100%,可全程记录整个实验过程中的肌电生物反馈仪放松反馈状态信息。结论利用图像动态跟踪识别技术提取目标设备状态信息是一种对目标设备无干扰的一种新方法,具有较好的应用前景。
Objective This article puts forward a completely new technical design based on video image processing and realize the data collection of EMG bio-feedbaek equipment under the conditions of no interruption of target equipment. Method Specifically, by gathering real-time video images without changing the original device, it is aimed to identify and follow the position of the signal light of EMG bio-feedback equipment in every image, and thus obtain the data gathering in the relaxed state. Result The accuracy rate of identifying and following the signal light position in EMG Bio-feedbaek Equipment is 100%. This method records the feedback information in the relaxed state in the whole experiment course. Conclusion Utilizing the image dynamic following and identifying technique to obtain target equipment information is a new method, and has a good prospect of application.
