Automobile electric tail gate control method and system
The invention provides an automobile electric tail gate control method and system. N frames of echo data of an automobile tail gate are periodically collected based on a UWB radar; for each frame of echo data, processing the echo data to obtain a distance-Doppler graph of the echo data; cutting the distance-Doppler map of each frame of echo data by using a preset kicking speed-distance threshold range; selecting each amplitude greater than a preset amplitude threshold value from a plurality of amplitudes of the distance-Doppler map of each frame of cut echo data as each target amplitude of each frame of echo data; according to each target amplitude of each frame of echo data, determining a kick feature of each frame of echo data; performing identification according to the kicking features of each frame of echo data through a pre-trained kicking action identification model to obtain a corresponding identification result; if the identification result is the kicking action, the automobile tail door is controlled to be opened or closed.
本发明提供一种汽车电动尾门控制方法及系统，周期性基于UWB雷达采集汽车尾门的N帧回波数据；针对每帧回波数据，对回波数据进行处理，得到回波数据的距离‑多普勒图；利用预先设置的脚踢速度‑距离阈值范围分别对每帧回波数据的距离‑多普勒图进行裁剪；从进行裁剪后的每帧回波数据的距离‑多普勒图的多个幅值中选取大于预设幅值阈值的各个幅值作为每帧回波数据的各个目标幅值；根据每帧回波数据的各个目标幅值，确定每帧回波数据的脚踢特征；通过预训练的脚踢动作识别模型根据各帧回波数据的脚踢特征进行识别，得到相应的识别结果；若识别结果为脚踢动作，控制汽车尾门开启或者关闭。
