Latest Patents

One of Zhang's latest patents is a crossbeam designed for measuring deformation velocities of a surface of a material under dynamic loads. This innovative crossbeam includes a body, a first type of velocimeter, and a second type of velocimeter mounted on the crossbeam body. The crossbeam is attached to a measurement carrier that moves along the material's surface while applying a dynamic load. The first velocimeter measures the vertically resilient deformation velocity behind the action force, while the second velocimeter measures the vertical downward deformation velocity in front of the action force. This dual measurement capability allows for simultaneous and rapid data collection.

Another notable patent involves methods for extracting surface deformation features of an object based on linear scanning three-dimensional point cloud data. This method utilizes a three-dimensional measurement sensor to acquire data and eliminate the influence of abnormal data and textures. It accurately obtains sectional main profiles and generates a binary image based on deformation feature points. The process includes morphological operations to extract target deformation regions, ensuring comprehensive detection of deformation characteristics.
