摘要
数字图像处理技术是一种前瞻性、智能化技术,已广泛应用于工业、交通、医学等领域。沥青混合料的均匀性直接关系到沥青路面的路用性能和使用寿命,是导致沥青路面早期破坏的主要因素之一。基于数字图像处理技术的沥青混合料均匀性评价方法具有检测频率高、费用低、操作便捷、客观性强、实时连续等特点,一直备受广大工程研究者和建设者的关注。运用数字图像处理技术评价沥青混合料均匀性时,数字图像处理和均匀性算法是决定评价结果的关键。目前,国内外研究学者重点围绕图像去噪技术、图像阈值分割方法、均匀性评价方法等方面已取得丰富的研究成果,例如分析了图像采集的影响因素、图像增强方法适应性、粘连颗粒分割原理和集料识别特征参数,利用二维图像技术或CT扫描三维图像技术分析沥青混合料集料分布,建立均匀性算法、评价指标及标准,定量评价沥青混合料的均匀性。但是,目前沥青混合料均匀性数字图像评价方法及评价标准国内外尚未形成统一的规范。沥青混合料施工过程中摊铺均匀性和压实均匀性快速、实时、连续的数字图像评价技术报道较少。因此,沥青混合料均匀性数字图像评价技术在图像采集、数字图像处理、均匀性算法、实时预警反馈、程序开发等方面仍需进一步探索和研究。本文针对沥青混合料均匀性数字图像处理技术,探讨了沥青混合料均匀性数字图像评价方法的研究进展和发展方向。首先概括了国内外沥青混合料数字图像处理技术,然后综述了沥青混合料摊铺表面和压实沥青混合料表面集料二维均匀性及结构集料三维均匀性评价方法,最后分析了沥青混合料均匀性数字图像处理技术面临的问题并展望其前景,以期为沥青混合料均匀性数字图像检测评价技术的工程应用提供参考。
Digital image processing technology is a forward-looking,intelligent technology,which has been widely used in industry,transportation,medicine and other fields.The homogeneity of asphalt mixture is directly related to the road performance and service life of asphalt pavement,which is one of the main factors leading to the early damage of asphalt pavement.The homogeneity evaluation method of asphalt mixture based on digital image processing technology has the characteristics of high detection frequency,low cost,convenient operation,strong objectivity,real-time continuous and so on,which has been concerned by many engineering researchers and builders.When using digital image processing technology to evaluate the homogeneity of asphalt mixture,digital image processing and homogeneity algorithm are the key to determine the evaluation results.At present,researchers at home and abroad focus on image denoising technology,image threshold segmentation method,homogeneity evaluation method and other aspects have made rich research findings,For example,the influencing factors of image acquisition,the adaptability of image enhancement method,the segmentation principle of adhesive particles and the para-meters of aggregate recognition have been studied,and the aggregate distribution of asphalt mixture is analyzed by two-dimensional image technology or three-dimensional CT scanning technology,and the homogeneity algorithm,evaluation index and standard are emphatically analyzed to evaluate quantitatively the homogeneity of asphalt mixture.However,the digital image evaluation method and standard of homogeneity of asphalt mixture have not formed a unified standard at home and abroad.There are few reports on the rapid,real-time and continuous digital image eva-luation technology of the paving homogeneity and compaction homogeneity in the asphalt mixture construction process.Therefore,the digital image evaluation technology of homogeneity of asphalt mixture in image acquisition,digital image processing,homogeneity algorithm,real-time early warning feedback,program development and other aspects still need further exploration and research.In this paper,the research progress and development direction of the digital image evaluation method of homogeneity of asphalt mixture are discussed for the digital image processing technology of asphalt mixture.Firstly,this paper summarizes the digital image processing technology of asphalt mixture at home and abroad.Then,the two-dimensional homogeneity evaluation methods of asphalt mixture paving surface and compacted asphalt mixture surface aggregate and the three-dimensional homogeneity evaluation method of compacted asphalt mixture structure aggregate are summarized.Finally,the problems and prospects in the study of the digital image processing technology of homogeneity of asphalt mixture are proposed,so as to to provide reference for the engineering application of asphalt mixture homogeneity digital image detection and evaluation technology.
