摘要提出了一种基于多线激光和双目视觉技术的沥青路面平均纹理深度测量方法。该方法结合了轮廓法和数字图像技术。为了实现沥青路面轮廓的三维重建，基于三角测量原理建立了三维数学模型。图像处理技术有助于定位模型上每个点的精确坐标。此外，本文还将多线激光配对技术和极线约束技术引入到多线激光与双目视觉的图像匹配中。通过该模型和得到的空间方程，可以计算出沥青路面的平均纵断面深度值。根据轮廓法，建立了完整的纹理深度计算程序。一组现场试验的实施，以验证所开发的方法的可靠性。
Abstract A new measuring method of mean texture depth of asphalt pavement is proposed based on the technology of multi-line laser and binocular vision. The developed method is incorporated with the profile method and the digital image technology. A three-dimensional mathematical model is established based on the triangulation measuring principle in order to implement the three-dimensional reconstruction of asphalt surface profile. Image processing technology helps locate the exact coordinates of each point on the model. In addition, the techniques of multi-line laser pairing and epipolar restriction are introduced for the image matching between multi-line laser and binocular vision. Through the model and the spatial equations obtained, the values of the mean profile depth of asphalt pavement can be figured out. According to the profile method, an integrated calculation procedure of texture depth is established. A set of sand patch field tests are implemented to verify the reliability of the developed method.
