Análise estatística da qualidade das medidas das propriedades de forma de agregados com o uso do Processamento Digital de Imagens (PDI)

Abstract

The Digital Image Processing (DIP) is established as a tool for the characteriza>on of aggregate shape proper>es (shape, angularity, and surface texture). Among the main techniques of DIP used in the area of Transport Infrastructure is the use of the Aggregate Imaging Measurement System (AIMS). This paper AIMS to evaluate the quality of aggre-gate shape proper>es measurements generated by the use of two AIMS, through sta>s->cal analyzes of repeatability and reproducibility. For this reason, two aggregates of pho-noli>c origin, produced by different crushing processes, were collected. The results based on descrip>ve and inferen>al sta>s>cs showed that there was repeatability and reproducibility, which contributes to the selec>on of aggregates in the project phase with shape proper>es provided from distribu>on curves and not by mean values.
