Bug fixes

  • User Interface
    • Various bug fixes and improvements in the User Interface, mainly in the Processing Options window and Select Coordinate System window.
  • Project Management
    • Fix bug where a .p4d file could not be opened in some cases when the image location has changed.
    • Fix bug where wrong camera model was selected when opening a .p4d project file with minimum format.

  • rayCloud
    • Fix bug where depending the coordinate system used, MTPs where not at the correct position anymore when re-opening a project. This has as consequence that measurement objects (polyline, surface, volume) also appear at the wrong position.

What is new

  • Generate an orthomosaic from any plane
    • Define an orthoplane in the rayCloud and use it to generate an orthomosaic. This allows to generate orthomosaics for building facades, bridge piles, etc.
    • Define surfaces on facades and use them to generate the DSM. This allows to flatten the point cloud and generate orthomosaics for flat surfaces more accurately.
  • Scale and orient the 3D model
    Define the scale and orientation of the 3D reconstruction by creating scale and orientation constraints in the rayCloud. This is useful when having projects with unprecise or no image geolocation and when using no GCPs.
  • Redesigned Mosaic Editor
    The redesigned Mosaic Editor allows to edit the mosaic generated at step 3. The changes done to the mosaic can be directly visualized in the Mosaic Editor before saving them.
  • Create 3D models and maps from video files
    Create a new project using a video file.
  • Processing Options Templates
    Processing options templates can be used to initialize processing options according to the type of images to be processed and which outputs are desired.
  • Processing options window new layout
    A new layout for the processing options allows to easier find the different options for step 1, 2 and 3. Advanced options are displayable only on demand for advanced users.
  • More robust initial processing
    Increase the targeted number of extracted keypoints to reconstruct datasets with low image content or low overlap (e.g. fields). Decrease the targeted number of extracted keypoints to speed up processing for projects with very high overlap or for very large images with a lot of image content.
  • Initial processing calibration method based on image geolocation
    This new processing method allows to process datasets with very accurate image position and orientation. It uses the image geolocation to calibrate the images, i.e. to optimize the internal camera parameters. Processing is therefore faster.
  • New DSM generation method
    New DSM generation method (Inverse Distance Weighting) which improves the orthomosaic quality. The effect is mostly visible on building edges which appear sharper.
  • Download projects from the Pix4D Cloud account
    Download projects from your Pix4D Cloud account to process them on your computer.
  • Redesigned command line
    In order to change the processing options in the command line a processing options template file has to be used. No other command line option allows to change the processing options.

Improvements

  • Concepts and names
    • The Aerial, Alternative, Oblique Processing Type has been replaced by processing options templates used to initialize the processing options.
    • The Full and Rapid processing modes have been removed. It has been replaced by processing options templates, where for each template a Rapid/Low Res template exists, that provides fast low resolution results.
  • User interface
    Various improvements in the user interface such as:
    • New icons for part of the software.
    • Text section in the toolbar.
    • Integrated tutorials.
  • Installer and updates
    • Display the new version number in the automatic update window.
    • Display the version number in the installer wizard on the first page.
  • New project creation
    • Improved new project creation workflow. The user can easier select the accuracy of the image geolocation and can already set the output coordinate system. He can choose the processing options template to initialize the processing options according to the type of dataset to process and the desired type of output.
  • GCP/Manual Tie Point Manager
    • Import/export GCP/MTP image marks from 2 new formats:
      • Pix4D marks file (.csv)
      • XML Structure (.xml)
  • Coordinate systems
    • Additional support for vertical coordinate systems:
      • Allow conversion between MSL and WGS84 ellipsoid
      • Do not convert altitude
    • Improved user interface that displays either general or advanced options to select the coordinate system.
    • Automatically detect coordinate system when possible.
  • Quality Report
    • Display time spent for processing for step 1 (without report generation), step 2, and step 3.
    • Display all processing options used.
  • Outputs
    • Export the image position of all the automatic tie points to a .txt file.
    • Save undistorted images for fisheye cameras.
    • Export the 3D Texture Mesh as FBX or AutoCAD DXF.
  • rayCloud
    • More navigation modes available to navigate in the 3D model. Choose between standard, trackball and first person navigation.
    • Display initial image and GCP position in output coordinate system in the right sidebar.
    • Display Check Points in orange to distinguish from GCPs.
  • Index Calculator
    • Import/export region boundaries from shapefile.
    • Define a prescription for all Regions of a given Class at once.
    • More color maps available for the index classes.
    • Export Colored Index Map as KML and PNG.
  • Command line
    • The Quality Report is now generated as .pdf when processing using the command line.
    • Allow to login/logout from the software using the command line.
