Digital image processing based aggregate measurement system

摘要

ABSTRACT TITLE.: DIGITAL IMAGE PROCESSING BASED AGGREGATE MEASUREMENT SYSTEM An digital image processing based aggregate measurement system for measurement of profile of aggregates of concrete mass is disclosed that includes an aggregate tray that is movable in a linear path two positions between two posts and that is rotated by predefined angles in the second position to capture at least six photographic images of an aggregate particle in the aggregate tray with at least three imaging devices. The apparatus also includes a plurality of LED lamps that are positioned at predefined locations to illuminate the background of the aggregate particle at the time of capturing the predefined images to avoid any shadow of the aggregate particle in the respective photographic image. A controlling unit positioned in close proximity with a first post controls an operational cycle of moving the tray for capturing predefined photographs of the aggregate to generate a profile of the aggregate in the tray.
