Title: Innovations of Dening Lu in Point Cloud Technology
Introduction
Dening Lu is a prominent inventor based in Jiangsu, China, known for his contributions to the field of point cloud technology. With a total of four patents to his name, he has made significant advancements in methods related to the extraction and measurement of rivet points in three-dimensional point clouds.
Latest Patents
One of his latest patents is titled "Method for extracting rivet points in large scale three-dimensional point cloud based on deep learning." This innovative method involves calculating the geometric attribute scalar of a point cloud of aircraft skin on a point-by-point basis. The scalar attribute domain is then mapped to a two-dimensional image, resulting in a two-dimensional attribute scalar map of the point cloud. A convolutional neural network processes this map to calculate the probability of each point being a rivet point. The rivet point cloud is subsequently divided through a threshold based on this probability, and points belonging to the same rivet are clustered using Euclidean clustering.
Another notable patent is the "Method for automated flushness measurement of point cloud rivets." This method includes extracting a rivet outline using an RANSAC circle fitting algorithm, which helps determine the center, radius, and normal vector of the outline circle. It also involves extracting the point cloud of a rivet head for a single rivet outline and generating a distance color difference map that reflects rivet flushness. This innovative approach allows for rapid and effective measurement of rivet flushness.
