openframeworks - saving kinect reconstructed 3d view into a file -

i'm going run project; reconstruct room kinect.

in format 3d reconstructed view saved ?

could save or convert 3dm, 3ds, max, obj , etc ?

thanks!

you can save 3d coordinates ply format. here's basic example using ofxkinect:

void exportplycloud(string filename, ofmesh& cloud) {     offile ply;     if (ply.open(filename, offile::writeonly)) {                 // write header         ply << "ply" << endl;         ply << "format binary_little_endian 1.0" << endl;         ply << "element vertex " << cloud.getvertices().size() << endl;         ply << "property float x" << endl;         ply << "property float y" << endl;         ply << "property float z" << endl;         ply << "end_header" << endl;          // write vertices         vector<ofvec3f>& surface = cloud.getvertices();         for(int = 0; < surface.size(); i++) {             if (surface[i].z != 0) {                 // write raw data if stream of bytes                 ply.write((char*) &surface[i], sizeof(ofvec3f));             }         }     } } 

you can use meshlab process/stich ply files , export them format obj. related openframeworks, can find few handy examples including above ply export in workshop.

saving ply solve part of problem , you'd need manually stich can time consuming. need slam(simultaneous localization , mapping) or other reconstruction algorithms stitch things together. can find nice collection of algorithm on openslam.

now depending on level of comfort coding there few options that. recommend having @ rgbdemo built software has reconstruction feature. requires no coding, unless want (as it's opensource).

with bit of coding can reconstruction using pointcloudslibrary(pcl). if includes implementation of kinectfusion

if you're using microsoft kinect sdk, kinect fusion integrated kinect sdk 1.7

you might find post interesting: kinect fusion inside autocad.
