kinect point cloud

    just using the saturation value (close range). manually aligning the texture to the depth, which isn't really right: it needs to be projected onto the depth map.

    note that this uses hector's default 'gamma' function, but what really needs to happen is taking the inverted reciprocal 1/(1-x) as i'm pretty sure the 11-bit image returned by the depth sensor is a disparity image. edit: i just posted a function for converting to meters here github.com/OpenKinect/openkinect/wiki/Imaging-Information

    if you want to see this in realtime, swap out the glview.c from your copy of the github openkinect project with the glview.c posted on the OF board: www.openframeworks.cc/forum/viewtopic.php?f=14&t=4947...

      want some video?
      :)

    7. Kyle McDonald (31 months ago | reply)

      yes please :) ideally with some big movements and maybe even moving the camera around :)

      those are glitches i accidentally added due to manually cropping the depth image: a little white along the border shows up as a line.

      Holy crap! Does this mean we will be able to create 3d models with it?

    16. Kyle McDonald (31 months ago | reply)

      definitely, using a few scans and then some post processing in meshlab or blender you can align, mesh, and zipper them. not easy, but significantly easier than before.

      No doubt some clever cookie will cook up something. It will be a fine day when I can scan a component into solidworks or the like using a kinect. No idea how much commercial scanners cost though.

      Very impressive point cloud for close range..

      mr.russ: something like what Kyle was talking about: vimeo.com/7489094 ;)

      i have one of those, in black, sitting behind me (donated by makerbot labs) :)

      I have seen that video before Tiago when I was looking at turning a photogrammetry generated pointcloud into a mesh. :)
      Ah 3D printers & scanners, so much fun to be had. It really is an engineers world ;P.

    22. Tiago Serra (31 months ago | reply)

      Hopefully it will not be an engineers world when we all have 3dprinters and scanners at home, but we're getting there ;)

    23. Tiago Serra (31 months ago | reply)

      Kyle, just curious, Kinetic is awesome alright, I had to buy one :1, but have you considered implementing other photogrammetry methods like using different light sources for a better textured face scanning like this?

      Not always perfection is the most creative thing to accomplish though....

    24. Kyle McDonald (31 months ago | reply)

      i have considered some other methods like this but they generally involve complex LED lighting rigs that are expensive or require lots of calibration. i'm more interested in the most DIY stuff that doesn't require much in the way of expertise or resources :)

      Agree, thanks :)
