| 中文摘要: |
| 本文开发了一种基于图像识别技术的土石料粒径级配检测系统。该系统修建在土石料填筑现场，通过对车辆运送的土石料进行拍照，将图片传输到识别系统，采用图像识别技术，分析土石料粒径并绘制级配曲线以判断土石料是否满足设计包络线要求。在此基础上，设计建造了一个小型土石料粒径识别系统样机，选取不同粒径范围的石英岩土石料，将图像识别得到的级配曲线与传统人工筛分法得到的级配曲线进行对比，发现二者级配曲线吻合度较好。表明本文开发的土石料级配检测系统是稳定可靠的，可以运用于现场坝料级配检测。 |

| This paper develops a rockfill material size gradation testing system based on image recognition technology. The system is built on the rockfill filling site, through the multi-faceted photographing of the rockfill materials transported by the vehicle,the picture is transmitted to the identification system,and the image recognition technology is used to analyze the particle size of the rockfill and draw a gradation curve to determine whether the rockfill materials meet the design requirements. Based on this, a small particle size identification system for rockfill materials is established, and quartzite materials with different particle size ranges are selected. The gradation curve obtained by image recognition technology is compared with the gradation curve obtained by traditional artificial screening method. Two gradation curves have a good degree of agreement. It is proved that the gradation testing system developed in this paper is stable and reliable, and can be applied to actual engineering rockfill material gradation testing. |
