图像与雷达数据关联的输送带跑偏与料位检测方法研究
Research on Conveyor Belt Deviation and Material Location Detection Method by Image and Radar Data Correlation
针对传统输送带跑偏与料位检测存在精度低、装置环境适应性差和高成本等问题,提出一种基于图像与雷达数据关联的输送带跑偏和料位检测新方法。该方法利用Mask R-CNN模型对输送带场景图像进行实例分割,以拟合输送带边缘,并根据托辊面积比判断跑偏情况;同时,对雷达数据进行预处理,采用Bowyer_Watson算法构建Delaunay三角剖分,生成高程图像;随后,利用K‑means聚类算法简化高程图像,通过灰度均值滤波进行料流分类;最后,将分类结果与图像信息关联,以展示料流的位置和状态信息。实验结果表明,该方法在实际场景中跑偏检出率超过95%,料位检测准确率超过80%。较传统方法,该方法具有更高的鲁棒性和检测效率,可实现输送带跑偏与料位的高效可靠检测。
Aiming at the problems of low accuracy, poor adaptability of device environment and high cost of traditional conveyor belt deviation and material location detection, a new method of conveyor belt deviation and material location detection based on the association of image and radar data is proposed. The method utilizes the Mask R-CNN model to segment the conveyor belt scene image by instances to fit the edge of the conveyor belt and to judge the deviation based on the area ratio of the rollers. At the same time, the radar data are preprocessed and the Bowyer_Watson algorithm is used to construct the Delaunay triangular section to generate the elevation image. Subsequently, K‑means clustering algorithm is used to simplify the elevation image and classify the material flow by gray scale mean filtering. Finally, the classification results are associated with the image information to show the location and state information of the material flow. Experimental results show that the method achieves more than 95% deviation detection rate and more than 80% material location detection accuracy in real scenarios. Compared with the traditional method, the solution has higher robustness and detection efficiency, and can realize the efficient and reliable detection of conveyor belt deviation and material location.
