Latest Patents

One of Jihui Zhang's latest patents is an apparatus and method for estimating camera orientation relative to the ground surface. This invention involves an iterative multi-image camera orientation estimation process. It includes capturing an image of a scene, detecting line segments, and computing a maximum likelihood camera orientation. The method optimally aligns the camera's coordinate system with the detected line segments in various orthogonal directions. Additionally, it estimates a maximum a-posteriori camera orientation that balances prior and maximum likelihood orientations, iterating until uncertainty is minimized.

Another notable patent by Zhang is a method for estimating camera orientation relative to a ground surface. This method detects line segments from captured images and superimposes virtual cubes with varying 3D orientations. By iteratively adjusting the orientation of the second virtual cube, the optimal orientation is computed based on the shortest perpendicular distances to the line segment groups. This innovative approach enhances the precision of ground orientation calculations.
