This paper presents a general texture mapping framework for image-based 3D modeling. It aims to generating seamless texture map for 3D model created by real-world photos under uncontrolled environment. Our proposed method addresses two challenging problems: 1) texture discontinuity due to system error in 3D modeling from self-calibration; 2) color/lighting difference among images due to real-world uncontrolled environments. The general framework contains two stages to resolve these problems. The first stage globally optimizes the registration of texture patches and triangle faces with Markov Random Field (MRF) to optimize texture mosaic. The second stage does local radiometric correction to adjust color difference between texture patches and then blend texture boundaries to improve color continuity. The proposed method is evaluated on several 3D models by image-based 3D modeling, and demonstrates promising results.
