If you don't have a CSV file with calibration information, you can input calibration values manually at the next step. If you are using the panel for the first time, and its calibration is not added to Metashape Pro internal database yet, you will be prompted to load a calibration from a CSV file: If the panels are not located automatically, use the manual approach described in Appendix A.
Press Locate Panels button:Īs a result, the images with the panel will be moved to a separate folder and the masks would be applied to cover everything on the images except the panel itself. Open Tools Menu and choose to Calibrate Reflectance option. If there is no such information in the image meta-data, the calibration images will be detected automatically at the next step or they can be manually arranged to a camera folder for calibration images in the Workspace pane if a custom reflectance panel is used for the calibration. The images will be disabled automatically (not to be used in actual processing). Metashape Pro can automatically sort out those calibration images to the special camera folder in the Workspace pane if the image meta-data says that the images are for calibration. Please remember to add reflectance calibration images! If the images are stored in several folders, the same operation should be repeated for each folder.
In the Add Photos dialog choose Multi-camera system option: Select all images including reflectance calibration images and click OK button. Open Workflow menu and choose Add Photos option. Images from MicaSense RedEdge, MicaSense Altum, Parrot Sequoia and DJI Phantom 4 Multispectral can be loaded at once for all bands. The MicaSense Altum dataset can be downloaded from MicaSense web-site: If reflectance calibration procedure is not applied (cannot be done without radiometric panel or DLS sun sensor data), MicaSense would only apply to vignette corrections, providing that the related information was stored in the image metadata.
