3D reconstruction with R-3D-2

About 3D reconstruction with R-3D-2 Android App

3D reconstruction from video/images is now a mature and extremely useful technology, though it can be challenging to obtain good results where the object/terrain is large, illumination cannot be controlled, under vibration, where multiple videos exist of an object of interest, with partial or temporary occlusions, etc. in which case a substantial amount of preprocessing might be necessary prior to the 3D reconstruction process, which can be tricky in itself.

R-3D-2 is a tool aimed mainly at professional users - such as engineers, designers, sales people, quality control, realtors, surveyors, archaeologists - who need to obtain a 3D reconstruction model from either video or a series of images for applications such as reverse engineering, monitoring construction progress, archaeologists, sales, remote sensing, or just for fun!

Capture and display can be done using a smartphone or camera and then imported into the app, while the processing is done by a powerful dedicated server (visit www.r-3d-2.com for examples, manuals and technical support). We provide users with a range of parameters that can be adjusted in order to obtain the best 3D reconstruction possible, as well as advice as to how best to do 3D reconstruction depending on the circumstances, ranging from obtaining CAD data of an object to be reverse-engineered to terrain reconstruction to be compared to a digital elevation model.

Useful support functions currently include functions to:

* The highest reconstruction quality achieved by image correction done by characterizing each mobile's sensor using Zernike coefficients.
" The only software able to do reconstruction in the visible or long-wave infrared (thermography) range.
*Built-in image processing toolkit
" 3D editor for THREE.js
" Basic video manipulation functions such as segment extraction, joining videos of the same object of interest, image extraction, format convertiom,
importing images/video into the currently selected project, exporting images/video.

Note: to calibrate the camera, please, download and print the pattern from the server.
