The invention discloses a pavement flatness detection method based on a vibration sensor. The method comprises the following steps: acquiring collected vibration sensor data; the vibration sensor data comprises acceleration perpendicular to the ground direction; determining relative variation and direction according to the acceleration and the reference acceleration; judging whether the data of the vibration sensor is a peak value or not according to a preset upper threshold value, a preset lower threshold value, a preset relative variable quantity and a preset direction, and combining adjacent peak values for reporting so as to obtain a complete event; and determining the pavement flatness according to the complete event, and obtaining a flatness detection result. According to the method, the peak values in the vibration signals are detected in a mode of combining multiple groups of threshold values and statistical values, the adjacent peak values are combined into one event, and finally, the pavement flatness is judged by analyzing the event, so that repeated reporting of a single disease can be avoided, the accuracy of a detection result is improved, the requirement on hardware is low, the cost is low, and the method is suitable for popularization and application. And the method has a certain self-adaptive capability to road condition changes.
本申请公开了一种基于振动传感器的路面平整度检测方法，包括：获取采集到的振动传感器数据；振动传感器数据包括垂直于地面方向的加速度；根据加速度和基准加速度确定相对变化量和方向；根据预先设置好的上阈值、下阈值、相对变化量和方向判断振动传感器数据是否为峰值，并合并临近峰值进行上报，从而得到完整事件；根据完整事件确定路面平整度，并得到平整度检测结果。本申请采用多组阈值与统计值结合的方式检测振动信号中的峰值，并将临近峰值合并为一个事件，最后通过对该事件的分析完成对路面平整度的判定，可以避免单一病害重复上报，提高了检测结果的准确性，且对硬件要求低，成本低，对路况变化具有一定的自适应能力。
