Photogrammetric texture mapping of complex objects
- 1. Photogrammetric texture mapping of complex objects Valanis A., Fournaros S., Georgopoulos A. Laboratory of Photogrammetry of NTUA (GREECE)
- 2. INTRODUCTION some of the most common problems of texture mapping applications include: Occlusions shadows non-orientable images streched areas gaps
- 3. MOTIVATION The application of photogrammetric methods Allows for the accurate registration of multiple images of the object Enables the elimination of occluded areas, streched areas and gaps And thus facilitates the creation of high resolution textures
- 4. Acquisition of multiple images
- 6. Image to surface projection
- 7. Creation of low-polygonal model
- 8. Creation of texture maps
- 10. Texture Blending
- 11. VRML models for web interaction
- 12. Textured models for HD video
- 13. Thank you for your attention! (e-mail: artvalanis@gmail.com)

- 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.
