The invention discloses a collision event determination method and device, equipment and a storage medium, which are used for improving the accuracy of collision event determination. The method comprises the following steps: performing weighted fitting processing on an acceleration original signal acquired in a first period based on a gyroscope signal acquired in the first period to obtain a first optimized signal; filtering the first optimized signal to obtain a second optimized signal; performing weighted fitting processing on the second optimization signal based on a gyroscope signal obtained in the first period to obtain a target optimization signal; obtaining a target signal corresponding to the second period based on the target optimization signal corresponding to each first period; and determining whether a collision event occurs in the second period based on the destination signal. Through the gyroscope signal, the original noise of the acceleration sensor is reduced, the sensitive noise of mechanical vibration in the acceleration original signal is reduced, the noise introduced by gravity and inclination in the acceleration original signal is reduced, and the accuracy of judgment of a collision event is ensured.

    本申请公开了一种碰撞事件确定方法、装置、设备和存储介质,用于提高对碰撞事件确定的准确性。本申请基于第一周期内获取到的陀螺仪信号对在第一周期内获取到的加速度原始信号进行加权拟合处理,得到第一优化信号;对第一优化信号进行滤波,得到第二优化信号;基于在第一周期内获取到的陀螺仪信号对第二优化信号进行加权拟合处理,得到目标优化信号;基于每个第一周期对应的目标优化信号得到第二周期对应的目的信号;基于目的信号确定第二周期内是否出现碰撞事件。通过陀螺仪信号降低了加速度传感器的原始噪声,减少加速度原始信号中机械振动的敏感噪声,减少加速度原始信号中由于重力、倾斜作用而引入的噪声,保证了对碰撞事件的判断的准确性。
