Import Pictometry survey

Not UAV

Import Pictometry survey command reads information from a text file and creates a mission file, an image list, and camera files. The text file can be created, for example, from the .DBF file delivered by the Pictometry system software.

The text file must include a specific set of columns which are delimited by tabulator. The two options for columns and their labels are:

NAME, OMEGA, PHI, KAPPA, X COORD, Y COORD, ALTITUDE, X PP OFFSET, Y PP OFFSET, FOCAL LENGTH, FOCAL WIDTH, FOCAL HEIGHT, K1, K2, K3, GPS TIME

IMAGENAME, IMAGEEXT, OMEGA, PHI, KAPPA, CAMERAX, CAMERAY, ALT, PPX, PPY, FOCALLEN, IMAGECOLS, IMAGEROWS, K1, K2, K3

The text file must have the extension .CSV. The camera parameters for each camera of the system are converted into a TerraPhoto camera calibration file. The time and positional information for the images are converted into a TerraPhoto image list.

To import a Pictometry survey index file:

1. Select Import Pictometry survey command from the Mission pulldown menu.

This opens the Import Pictometry survey dialog, a standard dialog for opening files.

2. Select the text file and click Open.

The Import Pictometry Survey dialog opens:

3. Define settings and click OK.

The mission file, an image list file, and camera calibration files are created in the given directory.
