¶ Introduction
Cameras manager is used to create, edit, exchange with projects, import and export camera and airplanes.
To calculate the coordinates of camera exposure moments (events), it is necessary to set the initial parameters, such as shifts of the center of the film plane of the aerial camera relative to the phase center of the satellite receiver antenna, installed on the aircraft, and the camera parameters.
¶ Open
To open Cameras manager select in program main menu Program Cameras item or by clicking 
button on a Toolbar.
Figure 19-1. Cameras and airplanes manager
¶ Add
Click Add Camera (
) or Add Airplane (
) button to add new camera or airplane.
Double click to edit name.
Сan't be saved more than one camera or airplane with the same name within one folder
¶ Edit
Activate Edit tab. After selecting camera or airplane is activated with corresponding data.
¶ Airplane parameters
| Name | Description | Image |
|---|---|---|
| Forw/back | Allows to set the offset, which is measured along the aircraft axis from the antenna phase center to the center of the film plane with the corresponding sign |  |
| Left/right | Allows to set the offset, which is measured across the aircraft axis from the phase center of the antenna to the center of the film plane with the corresponding sign |  |
| Vertical | Allows to set distance from the ARP antenna to the film plane, which is measured along the vertical axis. |
¶ Camera parameters
| Name | Description |
|---|---|
| The delay interval | Allows to set delay between the moment of camera exposure and the event time measured by the receiver. |
| Focal length | Allows you to set the focal length of the camera. |
| Distance to the film | Allows you to set the distance to the film plane, which is measured from the center of rotation of the camera to the film plane. The distance will be positive if the center of rotation of the camera is below the plane of the film. |
| Gyromount | If gyromount is checked, the camera was used “with a gyro platform”, and the camera orientation angles should be used when calculating the coordinates of the events. Otherwise, aircraft orientation angles should be specified manually(Main menu>>View>>Events). |
¶ Camera and airplane options
Right click on camera or airplane:
Figure 19-3. List of Camera and airplane options
¶ Properties
Click Properties for information:
Figure 19-4. Properties of Camera and airplane
¶ Import
Import Camera and airplanes from *.jac file
¶ Export
Export selected Camera and airplanes in .jac file
¶ Backup
¶ Create
A good idea is a creation of backup file for the camera and airplanes items. It helps in case of new Justin version installation or running software on several PC. Click Create back file (
) create file with name Param_Year-Month-DayTHours-Minutes-Seconds.jac in C:\Users\UserName\Documents\Justin\Cameras folder.
¶ Restore
Click Restore backup file (
) to restore camera and airplanes from a list of backup files from C:\Users\UserName\Documents\Justin\Cameras folder.
¶ Delete
Only user created backup files can be deleted. To delete click Restore backup file () then menu Delete and select menu with name of backup file.
¶ Exchange with project
Activate Project tab. All camera and airplanes of the currently open project will be presented in this tab.
Use 
and 
buttons to copy camera or airplanes from Camera or Airplanes to a project vice versa.
