Summary: | The invention discloses a gravity sensor data smoothing algorithm based on a dynamic window, and aims to solve the problem that the use effect of an existing data smoothing algorithm cannot meet the expectation of people. The core idea of the method is to judge whether a section of gravity data is stable or not by utilizing the dynamic window, if so, take the average value of the section of gravity data as the value of a stable state, and if not, discard the section of gravity data. According to the method, the calculation speed is high, the stability degree of the gravity data can be well judged, the data in the stable state can be extracted from the gravity data, and then the commodity recognition accuracy is improved. The memory occupied by the algorithm is small, the memory can be recycled, the space utilization rate is high, and the use prospect is wide.
本发明公开了一种基于动态窗口的重力传感器数据平滑处理算法,要解决的是现有数据平滑处理算法的使用效果达不到人们预期的问题。本发明的核心思想是利用动态窗口判断一段重力数据是否是稳定的,如果是则取该段重力数据的平均值作为稳定态的值,若不是稳定的则丢掉该段重力数据。本发明的方法计算速度快,可以很好地判断重力数据 |
