BLAM - Geometry camera matching add-on


Per from released an add-on for Blender which provides you with the tools to do a geometry camera matching over an existing still image similar to what SketchUp can do.

It features manual and automatic matching tools as well as focal length estimation and camera orientation. The perspective matching is done through using grease pencil strokes. The following video tutorial explains the process pretty well.

    YES!!! Finally a tool similar to the Sketchup Match Photo tool in Blender....ive been waiting for something like this for ages..

      • I have installed the addon, and  after i have  places a check mark on in the add on ANT landscape, and after to have the camera calibration panel in my uv/image editor i should to put a mark too in the addon 3d view : the blender camera calibration tool kit.
        now it is ok... in the tutoriel he don't say that we should to place a mark on this addon.
        it is ok now... and wow... it is to simple to use!
        thanks for the dragon's year!

    Oh man! I would literally pay money to make sure this add-on is the best it can be!
    I could never get those other camera-matching/resectioning solutions to work... whatever they were.

      yeah! The 
      camera-matching stuff is difficult, but maybe someday the "movie clip editor" and Blam"  will merge someday and make it easier to add 3d content io images and/or video.

    That's looking awesome & usefull. I wonder if this could join somehow with the camera tracker. Anyhow.. not enough time to write more.. I have to go outside, make photos and test that thing immedantly! :)

  4. great for architectural visualisation, as well!

    is there any way to define the length of a certain line within the image, so that the exact camera position can be determined?

    like after drawing in the vanishing lines, i mark the edge of a building in the photo, tell blender this edge is 3 metres tall and it places my camera?

  5. forgive a total newbie question ......but this is implimented how? All I'm seeing is a txt file with code when I hit the download link

    • Via python.
      Rename or blam.txt to, and import it into Blender via it's addon window in the preferences.

  6. Copy that, create a new text file, save that text file as . When you're done with that, go into user preferences with ctrl-alt-U and install the addon. Restart Blender and check the right box.

      • you just have to right click the addon hit save it to your blender addons folder,and you know the rest.if you double click the download you'll get the text file.or a security check.dont have to do any creating text files or changing anything :)

  7. hey all, I cannot for the life of me get thiss add-on to work. I installed into add-on folder and checked it . restarted but cant find any panels. are then suppose to be under the gp layers panel? does the panel only show after you draw the lines? any help would be appreciated,I have lots of travel photos that this would be perfect for tracking. thanks.

  8. I have finally gotten around to trying it out, and may I say it works quite well. (So far as I have used it). I am going to find it very useful for such VFX work as composting robots, explosions, etc... into still shots where the camera tracking wouldn't work to figure out where everything is.

  9. When I set this up my camera is flipped upside down, so basically scaling is all in the reverse. Has anyone else had this happen and is there a solution to fixing it?

      •  Well I contacted the author of BLAM with the problems that I was having and sent him a copy of my scene at his request but I never heard back from him. Per said that he has received reports on this problem but he has never been able to reproduce it. I suggest that you and anyone else having similar problems should get in touch with Per Gantelius: [email protected]

  10. This looks like it'll be really handy, but I can't seem to get this to install properly :( What all do I have to enable in the addons window? I have enabled 3D View: The Blender camera calibration toolkit and Add Mesh: ANT Landscape (as someone suggested above). The Camera Calibration panel is not appearing.

    it is beautiful but I need a rigorous photo matching, is there the possibly for to setup the scale of the camera whit my 3d model, whit some mark how 3ds?
    sorry for my English, I'm learning it and thanks a lot for all reply :)

  12. This was such a beautiful Camera Match solution, back then that is. It's been more than a few years now, I doubt it is compatible with the present Blender version : (
