Precise texture modeling with 3D laser scanning

Extremely precise texture modeling of complex 3D objects is a significant problem worth of much research. Comparing the laser scanning technology and the digital photogrammetry with their combination results, the optimal solution is the fusion of the data. Surveying points are used to model the main shapes while laser scanning captured the fine details. Photogrammetry is used to register the texture images with the geometry and produce ortho-texture. This paper explains a reliable method based on Direct Linear Transformation (DLT) and ortho-rectification method to model 3D objects combined with 3D laser scanning data and high-resolution image data. This novel technology can produce precise texture and improves the efficiency and quality of highly detailed texture modeling.
