Importing Photos with Metadata

Import photos of different data types into the project with their metadata (e.g., sensor width, focal length, and aerotriangulation data). When importing Inpho or Bingo results in a Cartesian coordinate system, such as ENU or ECEF, the AT step of the build process can be skipped (by selecting “Fully trusted input,” in the Camera Position Accuracy AT setting). Imported AT data in a projected coordinate system such as UTM, however, may be unreliable either due to earth curvature or earth curvature corrections performed in the other system. This is particularly true for datasets that contain oblique photos or large frames, or cover a large geographic area. For data of this type, aerotriangulation should be re-performed in PhotoMesh, i.e., use Reliable instead of Fully trusted for the Camera Position Accuracy AT setting.

Camera Definition

For each camera in the BINGO project file, enter the following information:

§  Camera ID – Camera name as it appears in the BINGO project file. This field is automatically filled in after the Import Project File is selected.

§  Columns – Number of pixel columns in a photo taken with this camera (image width).

§  Rows – Number of pixel rows in a photo taken with this camera (image height).

§  PixelSize – Camera sensor’s pixel size.

§  GridFile (Optional): File with camera distortion information that may be supplied by your data provider together with the BINGO file. This information can be applied during import to reduce image distortion. Click the button to open the Select Grid Calibration File dialog box. Then browse for the grid file.
