On Algorithm of Calorie Consumption Based on Monitoring Displacement of Gravity Center

针对现有的卡路里消耗算法在精准性方面的缺陷,提出了基于重心位移监测的卡路里消耗计算算法.以直立前行为例建立人体重心变换模型,利用移动终端的三轴加速度传感器获取监测数据计算重心位移变化,并实现对散步、跑步和踏步3种典型直立前行运动的自动识别和各自的卡路里消耗计算.对比实验验证了算法在卡路里消耗计算中的精准性.

At current m arket, a wide variety of intelligent m obile term inals has providedthe possibility forpeople to learn them selves＇ calorie consum ption in real tim e and conveniently. By analyzing the existing variouscalorie consum ption algorithm , it has been found th at there are defects in the accuracy of the algorithm. T h en , an algorithm ofcalorie consum ption based on m onitoring the displacem ent of gravity centerhas been proposed. T aking the vertical m ovem ent as an exam ple, the gravity center changing of body hasbeenm odeled. A nd w ith the m onitoring data obtained by the three axis acceleration sensor in m obile term inals,the displacem ent of gravity center has beencalculated,w hich is used to realize the autom aticalrecognitionof three typical vertical m ovem ents-w alking,running and stepping and calculate calorie consum ptionseperately.A com paring experim ent verifies the accuracy of the algorithm in the calculation of calorie consumption.
