The Study on Digital Imaging Technology of Real-time Mineral Mixture Gradation Detection on Construction Sites

摘要

In order to solve the problems of hysteretic and complex process in detection of mineral mixture, a new digital image acquisition system was designed in this paper that can meet the requirements of real-time detection onsite. It implements the all-weather imaging stably using infrared laser with a linear array digital camera. Through the installation of filters and the selection of the special background material to ensure image quality and reduce the difficulty on image processing. It has been confirmed that the capability of meet the needs of real-time detection to Mineral Mixture Gradation in experiments.
