GPU-Accelerated Point Registration:
Achieved a 10X performance improvement in the GPU-based ICP module for point cloud registration by utilizing KD-Tree for optimal nearest point pairing, learning point cloud statistics, removing outliers in the pairing process, and implementing other engineering optimizations.
3D Reconstruction Enhancement:
Increased point cloud generation speed by 20X through local plane fitting and hash checking, significantly expediting denoising and triangulation stages and reducing generation time from 170ms to 8ms. Enabled hole-filling functionality in the point cloud generation module, resulting in a final 3D point cloud with a three-dimensional resolution of 40 microns, capable of reconstructing gold metal surfaces.
