一个还算准确的计步器算法/a step count algorithm
为什么你要用手写的方式进行滤波,而不是用傅里叶变换的方式进行滤波呢?
gravityNew = (float) Math.sqrt(oriValues[0] * oriValues[0]
+ oriValues[1] * oriValues[1] + oriValues[2] * oriValues[2]);
这个代表传感器的值啊
如果本身传感器的值是带负值的,这样平方相加再开根号后,全部变成了正值,本文所采用的方法应当将步数/2,这样才对吧?
不知道iOS是不是重力感应传感器。
大神你好:
计步的时候有些时候会清零,请问你遇到过吗
你好,我想请问一下梯度化阈值的作用是什么?为什么要这么做?
