The embodiment of the invention provides a vehicle recognition method and device, computer equipment and a storage medium, and the method comprises the steps: collecting an original audio signal from the external environment of a current vehicle, recognizing the original audio signal generated by a special vehicle, and enabling the original audio signal to serve as a target audio signal, acquiring original image data and three-dimensional first point cloud data from the special vehicle according to the target audio signal, extracting an area where the special vehicle is located from the original image data by using the first point cloud data as target image data, recognizing the type of the special vehicle according to the target audio signal and the target image data, and using the audio signal as a screening condition to primarily screen the special vehicle, so that proper original image data and first point cloud data are selected, the number of the original image data and the number of the first point cloud data are remarkably reduced, the processing data volume for recognizing the special vehicle is reduced, the processing complexity is reduced, the recognition time consumption is reduced, and the accuracy of recognizing the special vehicle is improved.

    本发明实施例提供了一种车辆的识别方法、装置、计算机设备和存储介质,该方法包括:向当前车辆外部环境采集原始音频信号,识别由特种车辆产生的原始音频信号,作为目标音频信号,根据目标音频信号向特种车辆采集原始图像数据与三维的第一点云数据,使用第一点云数据从原始图像数据中提取特种车辆所处的区域,作为目标图像数据,根据目标音频信号与目标图像数据识别特种车辆的类型,利用音频信号作为筛选的条件对特种车辆进行初筛,从而选择合适的原始图像数据与第一点云数据,显著减少了原始图像数据与第一点云数据的数量,减少了识别特种车辆处理的数据量,降低处理的复杂度,减少了识别的耗时,并且,提高了识别特种车辆的准确率。
