Experimental study demonstrates robust visual counting of occluded stacked items in industrial containers, indicating viable automated inventory inspection.

Key Points

To develop a multi-view visual counting pipeline capable of accurately estimating the number of heavily occluded, stacked 3D manufactured items in industrial bins and containers.
Decomposed 3D object counting into two sequential subtasks: 3D stack geometry reconstruction and occupancy ratio estimation from multi-view image inputs.
Integrated geometric reconstruction algorithms with deep learning-based depth analysis to calculate counts of irregularly stacked, partially hidden identical parts.
Evaluated the pipeline across large-scale synthetic datasets and diverse real-world industrial datasets with manually verified ground-truth counts.
Accurately resolved occluded volume and spatial density distributions without requiring direct line-of-sight visibility for every individual item.
Achieved robust counting accuracy under complex, realistic inspection scenarios without physical weighing or container manipulation.
