Method and apparatus for detecting large block material, electronic device and computer program product
By acquiring event data streams through an event camera and discretizing them into a spatiotemporal voxel grid, feature extraction is performed to generate an edge energy map. This solves the problem of poor detection performance of frame cameras in high-speed transportation scenarios on conveyor belts in mining areas, and enables accurate identification of large pieces of material.
