| Abstract: | In order to complete the whole work of constituting a camera geometric calibration lab,algorithm and software are needed as a tool to calculate the photos.With 3D control grounds,the CCD-4Bands camera was calibrated utilizing close-range photogrammetry method.DLT(Direct Linear Transformation) method was analyzed and developed.Compared to the multi-image space resection,DLT had a good precision,and could be used to do geometric calibrations for remote sensing cameras. |
| Keywords: | laboratory calibration camera geometric calibration Direct Linear Transformation remote sensing sensor |
