3D reconstruction with R-3D-2

Obtain a 3D reconstruction digital model from either indoors or outdoors images.

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 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, etc.

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 for construction, agriculture or mining purposes.

Useful utilities currently include functions to:

* Extract a segment of MP4 videos.

* Join MP4 videos obtained from the same source.

* Extract constituent frames from a videos.

* Convert video in a wide range formats to MP4.

* Import images/video to currently selected project

* Export images/video from current project to SD card.

* Now able to produce 3D digital models from LWIR images.

We have now ported our optical system calibration module and distortion correction module. This will facilitate integration from multiple cameras. Soon, we will add this facility to the site itself with a more advanced capability.

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