DepthDCF: Multisensor Fusion-basedHigh-Quality Depth Estimation Dataset forDynamic Coal Flow

A high-quality dynamic coal flow monocular depth estimation dataset, based onmulti-sensor fusion, is presented to provide reliable support for the coal industry’sproduction, transportation, and processing stages. The dataset is meticulouslydesigned to address the specific requirements of coal flow monitoring. It encompasses three typical collection scenarios: coal handling galleries, manual gangueselection areas, and idle conveyor belts. The acquisition of high-precision, low-noise, and spatiotemporally aligned RGBD data was facilitated by the utilizationof ToF depth cameras and high-performance industrial cameras, thereby ensuring its suitability for operation in complex industrial environments, such as coalmines.
