    摘要： A method of implementing accurate digitization from a georeferenced image is described. In one embodiment, at least one set of coordinates which have been measured at a point of interest is received. A correction is then determined which describes a difference between the at least one set of coordinates and a set of georeferenced coordinates from a georeferenced image of the point of interest which describes the position of the point of interest.

    摘要： Embodiments provided herein recite methods and systems for an accuracy estimator for a position fix. In one embodiment, a solution receiver for receiving a code solution and at least one additional solution from a different solution technique is utilized. In addition, a table of metric values comprising an associated accuracy estimate for at least one characteristic of each of the code solution and the at least one additional solution is also utilized. A comparator compares the code solution and the at least one additional solution with the table of metric values. In addition, a solution orderer orders the at least one additional solution above or below the code solution dependent on whether the at least one additional solution is within a pre-defined offset distance threshold. If the at least one additional solution is outside of the distance threshold, the code solution is chosen as the final solution.

    摘要： Raw measurements for a plurality of GNSS satellites are pruned based on signal to noise ratio (SNR) and elevation; with remaining unpruned raw measurements sorted by SNR into a sorted list of raw measurements. A first dilution of precision (DOP) based selecting process is performed to select an initial candidate list of raw measurements. The first DOP selecting process begins by using at least those of said pruned list of raw measurements which exceed an SNR quality threshold. The initial candidate list of raw measurements is sorted by elevation angle. A second DOP selecting process is performed to select a final candidate list of raw measurements. The second DOP selecting process begins by using at least those of the sorted initial candidate list which an elevation quality threshold. The final candidate list is used in position computation for a present epoch.

    摘要： A method for estimating position and orientation of an image-capturing device is proposed. The method comprises the step of obtaining a preceding set of frames by using the image-capturing device. Each frame includes a set of image data. The method of the present technology further comprises the step of estimating a previous position and orientation of the image-capturing device by using the set of image data included in at least one preceding frame, and the step of estimating a current position and orientation of the image-capturing device by replacing a set of image data included in at least one preceding frame by a set of image data included in at least one subsequent frame. At least one subsequent frame is obtained by using the image-capturing device.

    摘要： A method of improving accuracy of position coordinates of a positioning device is provided. The method comprises: (A) obtaining a 3D reference solution for reference position coordinates of an positioning device by using a plurality of available radio signals emanating from an integer N number of available radio sources at time t; wherein 3D solution includes a reference 3D altitude of said positioning device at Epoch (t); (B) obtaining a barometric altitude of the positioning device at each Epoch; (C) if a trigger event occurs at Epoch (t+1), generating an updated altitude of the positioning device at Epoch (t+1) by using the reference 3D altitude obtained at Epoch (t) and by using the barometric altitude obtained at Epoch (t) and obtained at Epoch (t+1); and (D) using a position estimator to obtain 3D solution for position coordinates of the positioning device at Epoch (t+1) with improved accuracy by utilizing the updated altitude of the positioning device.
