Assign True Pose Tags

Requires an LP360 Geospatial Basic or higher, or an LP360 Drone license.

The Assign True Pose Tags feature of Add Files -> Photo tab tool on the Project Tab and Add Photo Layer tool on the Wingtra Tab allows photo layers to be created within LP360 from georeferenced photos if the photos have either EXIF tags or an EO file with the minimum necessary information for each photo. The minimum necessary information is:

• Latitude
• Longitude
• Elevation

How to Assign True Pose Tags to Photos

1. Before beginning Photo Import, a new (or existing) project must be opened in LP360.
   • To create a project when no project is open, select Save Project , then select the Project Root Folder, Project Name, optionally add a Project Description, and select the Project Coordinate Reference System (CRS) by browsing for the desired horizontal and vertical CRS.
2. Once the project is open, select either the Add Photo Layer tool on the Wingtra Tab of the ribbon, or select the Add Files tool on the Project Tab of the ribbon, then navigate to the Photo tab.
3. Select the  button to add the desired photos. Select all that apply, then select Open. The photos will then be added to the Add Photo Layer dialog (Figure 156).
4. Select the Assign True Pose Tags button on the bottom right-hand side of the dialog (Figure 1).

1. If using existing EXIF information:
   • Ensure the From EXIF option is selected, open the drop-down below Cam ID and select SerialNumber (Figure 1) or another tag that uniquely identifies the cameras used in this collection of photos.
   • Select the applicable attribute for the necessary columns. Latitude, Longitude, and Altitude are mandatory for importing photos. It is also recommended to include Roll, Pitch, and Yaw; however, these columns are not required.

1. If using an EO file in the Assign True Pose Tags dialog (Figure 3),
   • While the From EXIF option is selected, open the drop-down below Cam ID and select SerialNumber (Figure 1) or another tag that uniquely identifies the cameras used in this collection of photos. For instance, Make, works fine if you only have one camera.
   • Select From External EO File option at the top of the dialog (Only after having set the Cam ID). Select Browse to navigate to the EO file (Figure 3).
     • If the columns of the EO don’t appear properly, change the Delimiter to the respective option. If a Header row is included in the file, increase the Skip Line to exclude the Header.
     • Photo Name, Latitude, Longitude, and Altitude are mandatory for importing images using an EO file. It is also recommended to include Roll, Pitch, and Yaw; however, these columns are not required.
   • After all necessary columns are assigned, select ok. The values from the EO file should populate into the Assign True Pose Tags dialog. If the columns remain red, the file was not successfully added.

1. Select the CRS Selection button to choose the desired Geographic CRS for the photos.
2. Select the Auto Init Calibration button to populate starting values under the Camera Calibration Parameters Tag Mapping section. These values are needed to apply an existing calibration or to update the calibration for ortho generation.
3. Check the Use converted True Pose photos option and set the Export folder location at the bottom left of the dialog (Figure 3).
4. Select Ok, then select OK again to add the photo layer to the project.
5. You now have a Photos layer in your project from which you may now use with Image Explorer, Ortho Mapping , or Agisoft Ortho Mapping .
