基于DSP的沥青路面裂缝图像处理算法的实现

沥青路面裂缝是高速公路路面的主要患害之一。提出一种沥青路面裂缝图像处理算法，即采用改进的经典算法和形态学算法对沥青路面裂缝图像进行去噪平滑、边缘检测、图像分割、效果增强及边缘连接等处理。该算法通过DSP软件的检验，处理的效果相对于其它经典算法，有了显著的提高。对用谊算法处理后的沥青路面裂缝图像进行检测，检测的精度和检测效果都比较满意。

Realization of Image Processing Algorithm for Asphalt Pavement Surface Crack Based on DSP

The asphalt pavement surface crack is one of the main diseases of pavement surface in the highway. An image processing algorithm for asphalt pavement surface crack is put forward in this paper. It adopts the improved classical algorithms and morphological algorithms to process the asphah pavement surface crack image, such as avoiding noises, detecting the crack edges, image segmentation,optimizing images,jointing edges and so on. This algorithm is implemented in software form based on DSP. Compared with other classical algorithms, the processing effect by this algorithm is evidently improved. The detecting precision and effectiveness of this algorithm are good for detecting the asphah pavement surface crack.
