Project Hardware and Software



Here is a summary of the software and hardware I've been working with recently.

Software


Autodesk Recap - This is cloud based processing of imagery and produces 3D models.

  • Cost: Free with Academic License 
  • Pros: Does not require hardware to process imagery 
  • Cons: Requires time to upload imagery 

Autodesk Revit - This is building information modeling software that can be used to make 3D layouts from the Recap output.

Agisoft Photoscan - This is a commercial product. There are two versions: Standard and Professional.

  • Cost: 600 - 3500 USD. Free demo but lacks ability to export results. 
  • Pros: Ease of use. Does a great job processing with default parameters. 
  • Cons: Requires lots of RAM. 16 GB should be minimum. 

VisualSFM/CMPMVS - This is an open source product. This software allows the creation of 3D Models, orthorectified imagery, digital surface models.
  • Cost: Free. 
  • Pros: Free. 
  • Cons: Requires lots of disk space and CPU. Can be intimidating. 

Adobe Lightroom - This was useful for the DJI Phantom lens correction profile.


  • Cost: 79 USD
  • Pros: Lens correction profile for DJI camera. Easy to use contrast and histogram editing.
  • Cons: Cost.


Meshlab - This is software for editing 3D models. It can be used to clean up artifact from your models

Hugin - This is a free open source software for stitching images together. It is often used for creating panoramic photos.


Microsoft ICE - Like Hugin, this is a free software (closed source) for stitching images together. It can create panoramic imagery that is compatible with Photosynth.


Three.JS - This is a Javascript framework for working with WebGL. It allows 3D visualization of the OBJ files.

RealFlight 7.5 - This is software used to practice flying. It has very realistic physics and supports many types of vehicles from tri/quad/hex copters to fixed wing aircraft and traditional helicopters.
