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

Abstract:

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.

Fig. 14 Image path's Settings form Fig. 15 Database configuration information's Settings form 4 Epilogue The system uses infrared laser and linear array digital cameras' imaging technology that can filter out the imaging quality's influence on which the sunlight intensity changes have, so as to make it feasible mineral mixture grading test on production site in the all-weather condition. In the link of mineral mixture drop, we erect imaging system to collect discrete mixture image in order to ensure the validity of data acquisition. Acquisition images under the black background provide a strong support for high-quality images in the real-time detection analysis algorithm. Through the optical fiber repeater module, the image data collected by multiple linear array cameras was transmitted to main controlling computer of the regarding mix-proportion floor, which not only disarmed the limitation of transmission distance but also guaranteed the transmission efficiency. Using this set of imaging techniques' mixture detection system can realize mineral mixture gradation real-time detection at any time, and the result becomes much more scientific, objective and accurate, as well as it can avoid some problems of traditional testing methods relying only on artificially experience and environmental pollution.
