Import, Interior Orientations
Type: Utility accessed from various models
All images must have interior orientations before the stereo model can be set.
For digital images (including RPC satellite images) Interior Orientation is automatic. In Vr Model Set, Air Trig, and Vr Ortho it is done as soon as an image is added to a project. In Vr Two Orientation (which only exits now for legacy support) it accomplished using the batch import command (immediately below).
Film image interior orientations can be imported following the direction below.
The Import Interior Orientations in Batch dialog box
Import orientation file
Defines the ASCII file that contains the interior orientation measurements. The user must know the correct file for the import format. When importing Socket Set or Orima IOP files any single IOP file may be selected and all IOP files in the same folder will be used.
Interior orientation file format
Specifies the format of the input interior orientation file.
Depending on the Interior Orientation File Format selected, one or more additional dialog boxes may appear requesting more information about the input format. One of these dialog boxes may request information about the Photo Name Format. The Photo Name Format dialog box defines the format for decoding the strip number and photo number from and image file name.
If ISAT is selected as the Interior Orientation File Format, the following dialog box will display.
The ISAT Strip Number Location dialog box. Displayed when importing ISAT exterior orientations.
Strip number location
There are two possible locations for the strip number in the ISAT photo file.
begin photo_parameters 205 strip_id 2
would assume the strip number and photo number are included in the 205 field. The 2 after the strip_id would be ignored. If the number of strip characters were "1" and the number of photo characters were "2", then strip 2, photo 5 would be decoded from the 205 field.
begin photo_parameters 101 strip_id 3
would assume the photo number as 101 and the strip number as 3.
Selecting Images to Orient
The following dialog box is displayed before importing begins, allowing the user to select the images to orient. By default all images are selected.
