摘要
使用ADXL345三轴加速度传感器、nRF24L01无线收发芯片及USB接口芯片CY7C68013与上位机构建了一个人体动作信息测量设备。该设备由5组相同的动作测量模块、1组数据接收模块构成。动作测量模块置于人体四肢及躯干测量人体动作信息,数据接收模块通过无线方式收集加速度数据,并通过USB芯片上传给PC机,PC机计算出各部位的角度信息后绘制人体实时动作模型。通过与实际人体动作比较,该设备可以较好地反应人体动作情况,可以应用于多种人机交互场合。
A kind of human motion information measuring equipment is built by ADXL345 accelerometer, nRF24L01 radio transceiver, CY7C68013 USB interface chip and PC. This equipment is consisted of five groups of measuring modules and a data receiver module. The measuring module is placed on the limbs and trunk, measuring the human body motion information. The data receiver module collects body movement data from five measuring modules and uploads the data to PC via USB. PC calculates the angle information of each part of the human body and draw human body motion model in real time. By comparison with the actual human motion, the equipment responds well to the situation of human motion, which can be used to a variety of human computer interaction applications.
