Title:
HIGH-ENERGY-EFFICIENCY FPGA-BASED POINT CLOUD FEATURE EXTRACTION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/077729
Kind Code:
A1
Abstract:
One technical solution of the present invention provides a high-energy-efficiency FPGA-based point cloud feature extraction method, which is mapped to an FPGA for running. Another technical solution of the present invention provides a use of the high-energy-efficiency FPGA-based point cloud feature extraction method, wherein the method is used for point cloud feature extraction of unmanned driving or robots. Compared with the prior art, the innovation of the present invention is: providing a low-complexity projection method for organizing disordered and sparse point clouds, a high parallelism method for extracting coarse-grained feature points, and a high parallelism method for selecting fine-grained feature points.
