Advanced processing settings

Introduction to advanced processing settings

Pix4Dfields 1.5 brings advanced processing settings to give additional functionality and options to the user when generating the orthomosaic. These features are accessible after images have been imported and before start of processing. Guides can be found by following the associated links below.

Rig relatives calibration tool

Rig relatives calibration is available as of Pix4Dfields 1.4 and above. A detailed guide is provided here.

Radiometric correction in Pix4Dfields

Pix4Dfields 1.5 comes equipped with a new radiometry module. Besides the estimation of at-scene reflectance factors, it also includes support for automatic reflectance target detection. Radiometric correction is required to be able to compare images taken at different points in time under different weather conditions and to compute reliable index values. A detailed guide is provided here.

Weather conditions during capture

The user is asked to specify the weather condition during the image acquisition, such that sun angle correction can be performed. The user can choose between overcast or clear sky to specify the weather condition during the image acquisition. Fore more information read here.

Orthomosaic GSD

Since Pix4Dfields 1.6 the user can specify the desired Ground Sample Distance (GSD) of the computed orthomosaic. A GSD is the length of a pixel in the image in distance units (usually cm or inches). A smaller GSD implies a higher resolution and more detail, but also a larger image (in pixels, and therefore also in file size). A detailed guide is provided here.
