Edit Camera Events

The Edit Camera Events menu displays each camera event and it's associated image filename. In this context, an event refers to a timestamp, which then has associated position and attitude attributes derived from the active trajectory. The position and attitude information in the Edit Camera Events menu always reflects the current active trajectory.

Some image event operation tools are available at the bottom of the menu:

Load Image Filenames

This can be used to load images that are external to the current project. The most common use-case is for loading panoramic images from a Ladybug camera. Panoramic images can be loaded under any Receptor. Once loaded, georeferencing data can be written to the EXIF headers of the images using the Export menu. The same workflow can be used to write georeferencing data to the EXIF headers of PhaseOne imagery, in the case that the IIQ files are used for processing in SpatialExplorer and JPEG images are available externally (e.g. for orthomosiac production) .

Shift Events in Time

This can be used to apply an offset, in microseconds, to all events. This is useful when a bias or latency is present between the image capture time and event registration time.

Remove Selected Events

Can be used to remove camera events.

Export

The export menu is primarily used to export image georeferencing or timing information, for use in other software. The following export options are available to the user:

• Write Georeferenced data into JPEG EXIF Headers: this option writes the position of each image to the image's EXIF header. Orientation data is not written.

• Export active exposures of current receptor to CSV file: this is the most comprehensive metadata export, containing all of the fields listed in the Edit Camera Events menu.

• Export active exposures of current receptor to Pix4d file: this export option enables you to import the positions and orientations of the imagery into Pix4D and Metashape.

• Export active exposures of all receptors to TopoDOT: this option is used for importing imagery into TopoDOT.

These export formats can be selected from the Export menu, located at the bottom right hand corner of the Edit Camera Events menu:

Image positions and orientations will be exported referencing the active trajectory and project datum.
