Page 16 - 3DF Zephyr

3DF Zephyr has automatically identified through the Exif data of the photographs. In the Modify Calibration page, you can select the focal lenght you want to change (if loaded pictures have been taken with different focal lengths) and then define the calibration parameters. By the Import parameters from file button you can load a calibration files already created with an external application (see Lapyx 3DF). TIP: If you have imported pictures taken with wide-angle or fish-eye lenses it is recommended to activate the Adjust tangential distortion parameters option (10) Once the calibration step has been completed you have to set-up the first phase of the 3D reconstruction by means of the Camera orientation settings page, which will generate a sparse point cloud as initial 3D result. There are three settings way for the first three phases of 3D reconstruction (only in Zephyr Pro and Aerial): - Categories and Presets: is the fastest way to set the parameters of the reconstruction; - Advanced Mode: allows you to define every detail of the 3D reconstruction phases; - XML File Import: allows you to load an XML file where the user has already defined the most suitable parameters for its own reconstruction (recommended for professional
