Marso needs to know the relative positions of your lights to the sensor, as well as the order they will be triggered when capturing.
If you have not yet measured the lights on your capture system, please refer to this guide.
New Light Systems can be created from the settings menu, or when configuring a job.
New Light System Configuration
The upper left panel is used to create new light systems.
Existing ones can be selected in the upper right panel, and the light positions for the selected system will displayed in the visualization below.
Light positions are specified in meters, and are relative to the camera sensor, in the coordinate system shown below.
If your camera is in portrait or upside down, then Y ‘up’ relates to real-world up.
Your camera system must remain in the same orientation that you have used for the calibration image to maintain a consistent Light position relationship. It is okay if the internal gyroscope of the camera flips images landscape/portrait when shooting above the object.
Clicking the Add button creates a new row storing the light position once its XYZ coordinates have been entered. Each row should be populated and added in the order in which the lights will be turned on during a scan. If you have made a mistake during this process, or have the lights in the wrong order, select the incorrect row and use the remove button to remove a row.
Once all light positions have been added, the Light System should be given a name, and saved by using the Save button.
We have provided some example calibrations if you are having difficulties.
Loading a Light System
Similar to the exposure calibration, once the new Light System parameters have been saved, they will be stored and appear in the Light System Selection pane. Select the correct Light System for the current scanning setup used by selecting the corresponding row in the list, and clicking the Save button in the bottom right corner of the panel.
Selecting a row will display it in the visualization This can be freely rotated to confirm the light system looks correct.
