Item Automated texture mapping of laser based range images(Texas Tech University, 2005-08) Srisinroongruang, Rattasak; Sinzinger, Eric D.; Hernandez, Hector J.; Lakhani, GopalTexture mapping is the process of applying a 2D image onto a 3D planar surface. This requires the generation of a mapping that defines the relationship between the 2D coordinates of the image and the 3D coordinates of the surface. The goal of this research is to provide a method of automatically generating this mapping given a 3D object at arbitrary orientation and a 2D image that may contain unwanted background information. A review of the current methods of texture mapping, image segmentation, and basic 3D viewing transforms is given. An algorithm to compute this alignment given the proper segmentation of the 2D image is then proposed and tested with five different models. The results of the generated alignment and mapping are then discussed, showing the level of accuracy of the final texture mapped model.Item Automated texture mapping of laser based range images(2005-08) Srisinroongruang, Rattasak; Sinzinger, Eric D.; Hernandez, Hector J.; Lakhani, GopalTexture mapping is the process of applying a 2D image onto a 3D planar surface.
