The invention discloses a base line determination method based on a geomagnetic sensor, and an adaptive threshold method solves the problem that a base line cannot be updated in a fixed threshold method, but a clear method for selecting an initial base line is not given. A data set and a label set are obtained by collecting geomagnetic data of a parking lot where a geomagnetic sensor is located and video data shot by a camera in real time. After a normal vector and an intercept of a baseline are generated, reading data into a perceptron-based training model, and performing parameter adjustment through multiple iterations to obtain an initial baseline;

    本发明公开了一种基于地磁传感器的基线确定方法,自适应阈值方法虽然解决了给固定阈值方法中基线无法更新的问题,但对于初始基线的选取并没有给出明确的方法。本发明通过实时采集地磁传感器所处停车场的地磁数据和摄像头拍摄的视频数据,得到数据集和标签集。生成基线的法向量和截距后,将数据读入基于感知机的训练模型中,经过多次迭代来进行参数调整,得到初始基线。
