    Guidelines for photoshoots

    About equipment

    Photographing

  • Camera / mobile phone and a monopod or a stick
  • Drones with in-built cameras
  • This is what we have. http://www.parrot.com/products/bebop-drone/ Each battery last for about 10 minutes, there are 2 of them. 1 hour to charge, so optimally 4 rounds of shooting.

    Some other drones

    http://www.dji.com/product/phantom

    http://ardrone2.parrot.com

    https://www.lily.camera

  • Drone and an additional camera
  • Stillikameran kiinnittäminen phantomiin on myös mahdollista:

    http://www.shapeways.com/product/EP6MNPDMS/dji-phantom-universal-camera-mount-v2-1?li=shop-results&optionId=42942892

  • iPad + 3D scanner
  • abt 500€

    http://itseez3d.com

  • Helium balloons / kites + a camera
  • Nokia-kamerapuhelimen kiinnitys vaikka helium-palloihin voisi myös toimia.

    3d-mallin tekeminen kuvista onnistuu helposti Autodeskin 123d Catch -ohjelmalla puhelimessa tai PC:llä. Muitakin kaupallisia työkaluja on.

    The Open Source way 

    VisualSFM is good enough software to produce pointclouds from regular images: http://ccwu.me/vsfm/

    MeshLab

    http://meshlab.sourceforge.net

    The following is copied from http://wedidstuff.heavyimage.com/index.php/2013/07/12/open-source-photogrammetry-workflow/ and enriched with additions:

    Part 0: Camera calibration (optional)

    Capture series of images of printed checker board (or checker board on computer screen) and use f.ex 3DF Lapyx to calculate camera calibration parameters which will help the next phase

    Part 1: VisualSFM

    VisualSFM lets us load up a folder of images, find unique features in each image, solve a set of these images into a 3D model, and then refine that model into a dense point cloud. The two outputs of this step are:

    If you want to see a video of this process, check this out.

    Part 1.5: Dense matching with SURE

    With SURE you can calculate dense point cloud using the images and orientation files from VisualSFM. In general one 3D point for each overlapping image pixel is generated -> very detailed point cloud as a result

    Part 2: Meshlab

    Meshlab allows us to do basically anything to a 3D mesh or a point cloud. We’ll take the two outputs from the above steps and produce a textured, clean, high-res mesh. Meshlab also automatically calculates UV maps (the basis for 3D texturing) and builds a texture for us by estimating which projector is most accurate on each spot of the model, which is insanely cool. The outputs of this step are:

    Displaying point clounds on the web

    Vaihtoehtoisesti, patsaasta ja sen ympäristöstä voi tehdä point cloudin ja laittaa sen Potreetä käyttämällä esimerkiksi verkkoon:

    Creating panoramas

    Olen tehnyt Huginilla joitakin kokeiluja siitä, miten dronen videokuvasta saisi panoraaman tehtyä. Laatu ei dronen omalla kameralla ole ollut kovin häävi, skriptejä on täällä:
