3D Textured Surface Modeling

چکیده
Because object geometry varies at many scales, it is often convenient to distinguish shape from texture. While shape is a deterministic macroscopic description, texture is a finer scale geometric description with some repetitive or random component. The distinction between texture and shape is important when developing object recognition systems. Acquiring fine scale geometry is difficult due to local occlusions and limited resolution of imaging systems. Also, the complexities in geometric detail make geometric modeling of texture particularly challenging. Consequently, appearance is a convenient description for surfaces. A useful integration may entail geometry-based recognition for shape and appearance-based recognition for surface detail. We discuss our work on investigating and modeling surface detail using the framework of the BRDF (bidirectional reflectance distribution function) and the BTF (bidirectional texture function).

Creating Entirely Textured 3D Models of Real Objects Using Surface Flattening
We present a novel method to create entirely textured 3D models of real objects by combining partial texture mappings using surface flattening (surface parametrisation). Texturing a 3D model is not trivial. Texture mappings can be obtained from optical images, but usually one image is not sufficient to show the whole object; multiple images are required to cover the surface entirely. Merging pa...
متن کاملOcclusion-free Image Generation for Realistic Texture Mapping
Photo-realistic 3D models are nowadays required in many applications. The 3D modelling pipeline can be imageor range-based and often ends up with a visualization of a virtual textured model. One of the main problems encountered in texture mapping is the disturbance in the images by occlusions, which do not allow the generation of photo-realistic textured 3D models. Occlusions can be moving (e.g...
متن کاملAutomated modelling of real human faces for 3D animation
This paper describes the automated creation of a textured face mask of a natural person suitable for realtime animation. A 3D surface polygon face mask is used. A set of muscles is defined to animate the mask. The mask is adapted to a real person using 3D surface data from a calibrated stereo sensor. Firstly, the facial features of the mask are aligned to the 3D data by scaling the mask. Second...
متن کاملIntegration of Multiple Range and Intensity Image Pairs Using a Volumetric Method to Create Textured 3D Models
The reconstruction of highly detailed, 3D object models is a major goal of current research. Such models can be used in machine vision applications as well as for visualization purposes. The method presented here assumes that there are multiple range and intensity image pairs of an object, all registered to a global coordinate system. The individual range images are then used to create a surfac...
متن کاملPhotogrammetric Technique for Accurate Human Body 3D Model Reconstruction
Precise measurements of human body surface geometric parameters are very important for wide variety of applications such as medicine, identification, garment design and manufacturing etc. In most cases it is more convenient not to get measurements from a real subject but using his accurate 3D model. A photogrammetric technique for accurate human body 3D reconstruction is proposed. The hardware ...
