This paper presents a dataset of high-speed recordings of iron ore flowing on a laboratory-scale conveyor belt, captured with top-down videography and organized to highlight both regular operation and the presence of foreign objects. The conveyor belt measures 35 cm in width by 1.10 m in length. It operates at adjustable speeds and is powered by an electric motor to transport hematite and selected contaminants, such as wood pieces or plastic fragments. An NVIDIA Jetson TX2, equipped with its onboard OV5693 camera, recorded the footage at 120 frames per second in 1280 × 720 resolution, using a GStreamer pipeline to stream the video directly to disk. Individual frames were then extracted and sorted into subfolders, distinguishing normal operations from segments containing manually introduced anomalies. Additional subsets further categorize objects by type, enabling adaptation to various detection or classification approaches. This resource is intended to facilitate comparative evaluations of image-based detection approaches in a controlled mining context while also supporting extended uses in computer vision research related to industrial material transportation.
本文展示了一个数据集,该数据集是通过自上而下的摄像技术,对实验室规模的传送带上流动的铁矿石进行高速记录而获得的,并且经过整理以突出正常运行情况和异物的存在。传送带宽度为35厘米,长度为1.10米。它以可调节的速度运行,由电动机驱动,用于运输赤铁矿和选定的污染物,如木片或塑料碎片。配备板载OV5693摄像头的NVIDIA Jetson TX2以1280×720分辨率、每秒120帧的速度录制视频,使用GStreamer管道将视频直接流式传输到磁盘。然后提取单个帧并将其分类到子文件夹中,区分正常操作和包含人工引入异常的片段。其他子集进一步按类型对物体进行分类,以便适应各种检测或分类方法。该资源旨在促进在可控采矿环境中对基于图像的检测方法进行比较评估,同时也支持在与工业材料运输相关的计算机视觉研究中的扩展应用。
