Crop canopy height detection method, device, equipment and product

The invention discloses a crop canopy height detection method, device, equipment and product, and relates to the field of agricultural production.The method comprises the steps that canopy data of a to-be-detected crop is determined through a laser radar, the canopy data is projected to the ground plane, and first projection data and a first mapping relation are obtained; based on the first projection data, determining simulation cloth completely covering the first projection data; based on the first mapping relation, determining the process that the simulated cloth freely falls to the canopy data, and placing the original particles in contact with the canopy data in the free falling process and the canopy data between the adjacent original particles into a fixed particle set of the simulated cloth; particles located outside the first projection data in the simulated cloth are removed, and effective canopy data are obtained; and determining the canopy height of the to-be-detected crop based on the effective c
