本发明实施例公开基于运动传感器的路况分析方法、装置、设备及介质。该方法包括:将驾驶行为采集器的立体坐标系与交通工具的立体坐标系建立映射关系;获取设于所述驾驶行为采集器的运动传感器采集所述交通工具的加速度值;通过运动传感器进行姿态计算,将运动传感器的实际坐标转换为交通工具所在的坐标;依据所述加速度值对应分解到交通工具所在的坐标上的投影分量,所述驾驶行为采集器检测出所述交通工具所行驶路面的状况,获取路面状况数据;对路面状况数据进行分析,判断交通工具的驾驶行为。本发明获得了准确实时的路面状况数据,为后续UBI车险的驾驶行为分析或者交管部门分析交通事故提供了准确的辅助数据。

    The embodiment of the invention discloses a road condition analysis method and device based on a motion sensor, equipment and a medium. The method comprises the following steps of: establishing a mapping relation between a stereo coordinate system of a driving behavior collector and a stereo coordinate system of a vehicle; acquiring an acceleration value of the vehicle collected by a motion sensor arranged on the driving behavior collector; carrying out attitude calculation through the motion sensor, and converting the actual coordinates of the motion sensor into the coordinates of the vehicle; correspondingly decomposing the acceleration value to a projection component on coordinates where the vehicle is located, making the driving behavior collector detect the condition of a road surface on which the vehicle runs, and obtain road surface condition data; and analyzing the road condition data, and judging the driving behavior of the vehicle. Accurate and real-time road condition data are obtained, and accurate auxiliary data are provided for follow-up driving behavior analysis of UBI vehicle insurance or traffic accident analysis of a traffic control department.
