In order to solve the problem that the source of LiDAR data error needs to be adjusted and the data volume is large. the adjustment speed between the voyages is slow and cannot be automatically adjusted. Based on the iterative nearest point (ICP) algorithm. this paper proposes an improved iterative closest point (ICP) algorithm based on GPU parallel octree. https://safeersappliancers.shop/product-category/aeg-hg795840nb-75cm-wide-gas-hob-with-vertical-flush-burners/
