Latest Patents

One of his latest patents is titled "System and method for estimating three-dimensional measurements of physical objects." This invention provides a method and system for estimating three-dimensional measurements by utilizing readings from inertial sensors. The method involves capturing three-dimensional aspects of a physical object using a handheld unit. The raw recordings from the inertial sensors are used to develop a raw rotation matrix, which is then processed to obtain filtered Euler angles. This processed rotation matrix is crucial for estimating gravitational components along three axes, leading to the determination of acceleration values and the measurement of each dimension of the physical object.

Another significant patent is "Methods and systems for surface fitting based change detection in 3D point-cloud." This invention focuses on change detection utilizing three-dimensional point-cloud processing. The method includes detecting changes in surface geometry based on a surface fitting approach with a locally weighted Moving Least Squares (MLS) approximation. It effectively compares surface geometry of a reference point-cloud and a template point-cloud, providing reliable change detection for both rigid and non-rigid changes while minimizing false detections due to noise.
