Camera Calibration Photo
Each camera (referring to a camera and lens combination) used in a close-range photogrammetry project should be calibrated and a calibration file should be saved with the project data. Some close-range photogrammetry software does not require this information before processing the image block; however, it will provide most of this information after processing. The tables below describe what is appropriate to document for this process. Download a printable form in PDF format here or in a spreadsheet (.xlsx) format here.
For each camera/lens calibration:
| Element | Description |
| Camera/Lens name | Name used to identify this camera/lens combination (e.g. CAST5DmkII-2_28mm). |
| Date of calibration | Date that the calibration was performed. |
| Camera calibration file name | The exact file name for the camera calibration. |
| Camera specifics | Specific make and model of the camera and lens used. |
| Array dimensions in pixels | Width and height of digital array measured in pixels. |
| Array dimensions in mm | Width and height of digital array measured in millimeters. |
| Focal length | As indicated by camera calibration. |
| Principal Point | As indicated by camera calibration. |
| Lens distortions (K1, K2, P1 and P2 parameters) | Radial and decentering distortion parameters as measured by the camera calibration. |
| Affine distortions | Affine distortion parameters as measured by the camera calibration (if measured). |
| Calibration Quality Values | Quality values such as overall RMS, maximum residual, and photo coverage (%) from the calibration process. |
| Calibration adjustment report | A report on the quality of the camera calibration including the correlation between exterior and interior parameters. |
For each calibration image (if performing a camera calibration with a target):
| Entry | Description |
| Image file names | File names for calibration images. |
| Calibration target description | Include target dimensions, creator and description. |
