Latest Patents

One of Aliaga’s patents, “Method and Apparatus for Computing Error-Bounded Position and Orientation of Panoramic Cameras in Real-World Environments,” describes techniques for estimating a panoramic camera’s pose in large spaces, including buildings with multiple rooms. The method uses fiducials placed throughout an environment, captures images of them, and estimates camera pose from their projections. Fiducial placement and pose estimates can be optimized while accounting for constraints such as fiducial visibility, distance, and viewing angle.

Another patent, “Camera Model and Calibration Procedure for Omnidirectional Paraboloidal Catadioptric Cameras,” addresses calibration of cameras that combine mirrors and lenses. It accounts for perspective projection, radial distortion, and mirror misalignment. The procedure uses calibration points placed at known locations, images captured from different positions, and an optimization algorithm to fit the observations to a perspective camera model.
