The invention discloses a pavement texture measurement method based on acoustics, relates to the technical field of pavement texture measurement, and aims to solve the problem that the pavement texture measurement work is affected due to the fact that dirt existing on a pavement is easily attached to the surface of a tire when the tire runs on the pavement in the prior art. The method comprises the following steps of: 1, mounting a measuring device main body in front of an automobile for measuring pavement textures, and then starting the automobile to run on a pavement; 2, the surface of the tire is cleaned through a cleaning assembly, and dirt attached to the surface of the tire is removed; 3, video image collection is conducted on the road surface through a second camera, and noise generated in the tire running process is collected; 4, ultrasonic waves are emitted to the road surface, the ultrasonic waves can be reflected after making contact with the road surface, and reflected ultrasonic wave echoes are received; and 5, processing and analyzing the video image, the acoustic signal information and the echo signal information through an intelligent processor module to obtain the pavement texture.

    本发明公开了一种基于声学的路面纹理测量方法,涉及路面纹理测量技术领域,为解决现有技术中的轮胎在路面上行驶时,路面上存在的脏物容易附着在轮胎表面,影响路面纹理测量工作的问题。步骤一:将测量装置主体安装在用于路面纹理测量的汽车的前方,然后启动汽车在路面上行驶;步骤二:通过清理组件对轮胎表面进行清理,清理除去轮胎表面附着的脏物;步骤三:通过摄像头二对路面进行视频图像采集,且对轮胎行驶过程中产生的噪声进行采集;步骤四:并向路面发射超声波,这些超声波在接触到路面后会产生反射,对反射回来的超声波回波进行接收;步骤五:通过智能处理器模块对视频图像、声学信号信息和回波信号信息进行处理,分析得到路面纹理。
