Vehicle detection dataset

This dataset was created by extracting features from 76 hours of second-level signals for field vehicle detection. Each frame sample contains synchronized 1-second acoustic and seismic signals, and each dataset sample includes "acoustic_features" (10×256), "seismic_features" (10×64), "class" ('1' for train and '2' for test), and "label" ('1' for vehicle and '0' for no vehicle).本数据集通过提取76小时秒级（second-level）信号的特征构建，用于野外车辆检测任务。每个帧样本包含同步的1秒时长声学信号与地震信号；每个数据集样本包含声学特征（"acoustic_features"）（维度为10×256）、地震特征（"seismic_features"）（维度为10×64）、类别（"class"）（其中'1'代表训练样本，'2'代表测试样本）以及标签（"label"）（其中'1'代表存在车辆，'0'代表无车辆）
