Imagery captured with Parrot Sequoia camera is automatically recognized by the software since the camera is in PIX4Dmapper camera database.
1. Create a new project: Step 2. Creating a Project.
2. Import all discrete band imagery (green, red, rededge and NIR imagery) from the flight. This includes the images of the calibration target.
3. Choose the Ag Multispectral processing template: Processing options.
4. The radiometric calibration target images can be automatically detected and used by the software in certain conditions. For more information: Radiometric calibration target.
5. If the radiometric calibration target data is not detected automatically, this process can still be done manually. For more information: Radiometric calibration target.
6. Select the radiometric correction options corresponding to the device configuration you used to fly. For more information: Radiometric corrections.
7. Start processing.
1. Create a new project: Step 2. Creating a Project.
2. Import all the RGB images in the same project.
3. If the flight plan is linear, ensure the Linear Rolling Shutter model is selected: How to correct for the Rolling Shutter Effect.
4. Choose the Ag RGB processing template: Processing Options Default Templates.
5. Start processing.
The usage of a radiometric calibration target is not necessary with the targetless radiometric calibration of Parrot's Sequoia+. However, in order to use the targetless radiometric calibration of Sequoia+, the file sequoia_therm.dat is required. This file is generated automatically for each flight, is unique to each Sequoia+ and can be found for each set of images in the folder where the images are stored during the acquisition mission.
To process a project with Sequoia+:
1. Create a new PIX4Dmapper project: Step 2. Creating a Project.
2. Import your multispectral images, i.e. Green, Red, Red Edge, and NIR.
3. Click Next.
4. Select the Ag Multispectral processing template: Processing Options Default Templates.
5. Select the radiometric correction according to the lighting conditions when the images were captured: Menu Process > Processing Options... > 3. DSM, Orthomosaic and Index > Index Calculator.
5.1. Camera, Sun Irradiance and Sun angle for clear skies
5.2. Camera and Sun Irradiance for overcast skies.
6. Start processing.
