  • 239 images acquired and oriented
  • 327 control points acquired and measured (sw Topcon Image Master)
  • All oriented images were projected onto the object surface based on the collinearity model and an *.obj file was created for every image (swMatlab)
  • The low density polygonal model that was created manually in order to closely approximate the object surface and produce the basis for the texture maps (sw GSI)
  • The 4 texture maps that were created for texturing the 4 statues of the complex (swDeepUV)
  • 130 rendered texture images that were later blended into 5 texture maps (sw 3D Studio max)
  • The final texture maps as composed after blending the rendered texture images (sw Photoshop)
  • The final VRML model. The final model is textured with 4, 4K texture maps (one for each statue) and 1 2K map for the floor. Its total size is less than 11 MB and it may be viewed through an html browser after installing a free plugin such as the cortona 3D viewer or the cosmo player plugin.
  • Any textured model may be imported into an animation sw such as the Cinema 4D. By adding some basic components for the environment and by adjusting cameras and lighting such a video may be produced quite easilly.

    1. 1. Photogrammetric texture mapping of complex objects<br />Valanis A., Fournaros S., Georgopoulos A.<br />Laboratory of Photogrammetry of NTUA (GREECE)<br />
    2. 2. INTRODUCTION<br /> some of the most common problems of texture mapping applications include:<br />Occlusions<br />shadows<br />non-orientable images<br />streched areas<br />gaps<br />
    3. 3. MOTIVATION<br />The application of photogrammetric methods <br />Allows for the accurate registration of multiple images of the object<br />Enables the elimination of occluded areas, streched areas and gaps<br />And thus<br />facilitates the creation of high resolution textures <br />
    4. 4. Acquisition of multiple images<br />
    5. 5. Photogrammetric processing<br />
    6. 6. Image to surface projection<br />
    7. 7. Creation of low-polygonal model<br />
    8. 8. Creation of texture maps<br />
    9. 9. Texture rendering<br />
