The invention discloses an obstacle height identification method and device for autonomous parking, electronic equipment and a medium. The obstacle height identification method comprises the following steps: acquiring ultrasonic reflection echo information of an obstacle to be identified; performing down-sampling on the data points of the ultrasonic reflection echo information according to a preset distance interval to obtain echo height data of the ultrasonic reflection echo information; and inputting the echo height data into a trained neural network model for identification so as to obtain a high-low classification result of the to-be-identified obstacle. According to the method, the obstacle echo information is collected, and then the data points of the ultrasonic reflection echo information are subjected to downsampling according to the preset distance interval to extract echo height data so as to train the neural network model to classify the heights of the obstacles, so that the complexity of manual calibration and feature selection is avoided, the accuracy is ensured, the calculated amount is small, and the efficiency is high. The method is suitable for engineering implementation of the vehicle-mounted ultrasonic radar.

    本发明公开了一种自主泊车的障碍物高低识别方法、装置、电子设备及介质。所述障碍物高低识别方法包括:采集待识别障碍物的超声反射回波信息;按照预设的距离间隔对所述超声反射回波信息的数据点进行降采样以得到所述超声反射回波信息的回波高度数据;将所述回波高度数据输入到训练好的神经网络模型中进行识别,以得到所述待识别障碍物的高低分类结果。该方法通过采集障碍物回波信息,然后按照预设的距离间隔对超声反射回波信息的数据点进行降采样提取回波高度数据以训练神经网络模型进行障碍物高低分类,避免人工标定和选择特征的复杂性,确保准确性的同时计算量小、效率高,适合车载超声波雷达的工程实现。
