2results about How to "Reduce technical ability requirements" patented technology

The application discloses a kind of satellite radiation product-based remote sensing image geometric calibration method, electronic equipment and medium.The method can include: determining reference image, inputting image to be calibrated;For the same name point matching of image to be calibrated and reference image, obtain the same name point coordinates;The third polynomial distortion model about CCD probe element number is constructed;Based on the same name point coordinates, curve fitting is carried out on the distortion model, and the distortion coefficient is obtained;The resampling of image to be calibrated is carried out by distortion coefficient, and the correction of internal distortion of image is realized.The application can quickly and accurately carry out geometric calibration processing to satellite image, greatly improve the efficiency and quality of image processing.

The encoder counting wheel perimeter calibration structure comprises a supporting frame, a bottom plate is installed on one side of the upper portion of the supporting frame, a guide rail A is installed on the upper portion of the bottom plate, a sliding block A is installed on the guide rail A, a clamp fixing seat is installed on the upper portion of the sliding block A, a profile clamping clamp is movably installed in the clamp fixing seat, and the profile clamping clamp is movably installed on the lower portion of the supporting frame. A grating ruler parallel to the guide rail A is installed above the bottom plate and located on one side of the guide rail A. The principle utilized by the invention is basically consistent with that of manual calibration, and the difference is that the grating ruler is used for replacing the whole measurement process, a system program is used for replacing manual calculation and the whole calibration process, the whole measurement process can be fully automatically completed only by pressing a start button by a worker, manual participation is not needed in the process, the requirement on the technical capability of the worker is reduced, and the method is quicker, simpler and more convenient; and the grating ruler is used for surveying and mapping, which is more accurate than manual measurement with a tape measure, and the advancing distance of the material can be truly reflected.
