Digital imaging acquisition system for aggregate grading detection and acquisition method thereof

Abstract

The invention discloses a digital imaging acquisition system for aggregate grading detection. The system consists of an aggregate sampling device, an image acquiring device, an optical processing optimizer and communication and storage equipment, wherein the aggregate sampling device comprises a material dividing plate, a distance adjusting rod and an angle adjusting rod; the image acquiring device comprises an infrared laser, a linear array camera and an image acquiring card; the optical processing optimizer comprises a filter device and a diffuse coating layer; and the communication and storage equipment comprises a data line and a computer. A digital imaging acquisition method for aggregate grading detection comprises the following steps of: setting the aggregate sampling device; setting the image acquiring device; setting the communication and storage equipment; acquiring an image of a sampled aggregate; and transmitting and storing the image. An aggregate stream is sampled and acquired by arranging the material dividing plate, so the problem that the image of a falling stream of the aggregate must be completely acquired is solved and the defects of poor quality of the acquired image, difficult separation of particles and a large amount of processing data are overcome.

Description

Technical field [0001] The invention is an innovative method for real -time detection technology for asphalt mixture production process. It specially involves a digital imaging collection system and its collection method for collecting samples of materials. This method uses digital image processing and image recognition technology on the road surface construction.The asphalt hybrid production site was sampled in real time. Background technique [0002] At present, the highway pavement is mainly asphalt pavement.In the composition of asphalt pavement materials, the amount of materials set is the largest and the cost is the most.At the production site of the asphalt mixture, the grade matching of the material was only controlled from the mixing building unilaterally to control the amount of the various cold material warehouses, and did not perform real -time detection of the collection of materials.This often leads to the actual production level and design level of design levels to...
