Introduction

Sha Lu is an inventor based in Zhejiang, China, associated with Zhejiang University. His listed patent focuses on helping mobile robots recognize previously visited places using lidar data.

Latest Patents

Lu is credited with 1 patent: “Method for Place Re-Recognition of Mobile Robot Based on Lidar Estimable Pose.” The method uses a Radon transform to represent rotation and translation changes as shifts in a sinusoidal graph. It then applies spectrum cross-correlation to estimate image translation and, in combination with the Radon transform, can determine relative rotation and translation. Translation-invariant information supports the creation of position descriptors for matching candidate locations. The approach also considers changing environments and uses a multi-channel bird’s-eye-view feature representation to improve how local features in lidar point clouds are represented.
