20140043505 | METHOD AND SYSTEM OF INCREASING SPATIAL RESOLUTION OF MULTI-DIMENSIONAL OPTICAL IMAGERY USING SENSOR'S INTRINSIC KEYSTONE - A method and system for creating a high spatial resolution image from a multidimensional imagery is disclosed. The technique exploits an intrinsic spatial distortion of the sensor that acquired the imagery and uses it as additional information to increase spatial resolution of the imagery. The method comprises obtaining a baseline image from the multidimensional imagery; deriving n×m−1 sub-pixel shifted images from the multidimensional imagery, where n and m are spatial resolution increase factors in x and y directions respectively, integers and greater than 1; organizing the baseline image and the n×m−1 sub-pixel shifted images from the multidimensional imagery; fusing the organized images using iterative back projection (IBP) to generate a high resolution image; and outputting the generated high resolution image. | 02-13-2014 |
20120086598 | APPARATUS AND METHODS FOR DRIFTLESS ATTITUDE DETERMINATION AND RELIABLE LOCALIZATION OF VEHICLES - In order to determine positional information, about a mobile robot, Real Time Kinematic (RTK) Global Satellite Navigation System (GNSS) measurement data are obtained by at least two GNSS receivers mounted on the mobile robot. Estimates of the covariance matrices of the measurement data are computed. The RTK GNSS measurement data are combined according to the covariance matrices to obtain enhanced positional information. The results may be fused with data from an IMU to obtain driftless attitude and/or localization information. | 04-12-2012 |
