Latest Patents

Gang Liu's latest patents showcase his cutting-edge inventions:

1. **Composite Three-Dimensional Blob Tool and Method for Operating the Same**

This invention introduces a system and method for performing 3D imaging of complex objects, particularly where image data may be compromised. Utilizing both available image data and the absence of data, it enables the computation of the x, y, and z dimensions. The approach assumes that missing data signifies something obstructing accurate data generation, helping to establish a maximum bounding box around the object. Moreover, the method involves estimating various measurements, including the object's shadow size, to refine the imaging results.

2. **System and Method for Calibrating a Plurality of 3D Sensors with Respect to a Motion Conveyance**

Liu's second patent offers an innovative calibration object that simplifies the process of 3D sensor calibration. This dual-sided calibration target, suggested in a frustum shape, incorporates both accurate measurement features and repeatable characteristics to facilitate field calibration of opposite-facing sensors. The design enables straightforward calibration by utilizing the corner positions of the frustum along with a flange that provides essential absolute Z information.
