Abstract
We proposed a texture mapping technique that comprises mesh partitioning, mesh parameterization and packing, texture transferring, and texture correction and optimization for generating a high-quality texture map of a three-dimensional (3D) model for applications in e-commerce presentations. The main problems in texture mapping are that the texture resolution is generally worse than in the original images and considerable photo inconsistency exists at the transition of different image sources. To improve the texture resolution, we employed an oriented boundary box method for placing mesh islands on the parametric (UV) map. We also provided a texture size that can keep the texture resolution of the 3D textured model similar to that of the object images. To improve the photo inconsistency problem, we employed a method to detect and overcome the missing color that might exist on a texture map. We also proposed a blending process to minimize the transition error caused by different image sources. Thus, a high-quality 3D textured model can be obtained by applying this series of processes for presentations in e-commerce.
Highlights
Two-dimensional (2D) images are commonly used for product presentations in e-commerce because they can reveal the object’s texture and are easy to process
The object images can be obtained using a single-camera device that applies a digital single-lens reflex (DSLR) camera to capture an object placed on a turntable, or a multi-camera device that applies several DSLR cameras mounted on an arm to capture an object placed on a turntable from different angles
We propose an optimized texture transferring algorithm for generating the texture map, emphasizing the elimination of erroneous texture mapping owing to insufficient accuracy of the 3D model as well camera parameters, and the improvement of the texture resolution as close to that of 2D object images as possible
Summary
Two-dimensional (2D) images are commonly used for product presentations in e-commerce because they can reveal the object’s texture and are easy to process. Product presentation usually requires a dedicated photography device to catch high-quality object images with known position and orientation in 3D space. The object images can be obtained using a single-camera device that applies a digital single-lens reflex (DSLR) camera to capture an object placed on a turntable, or a multi-camera device that applies several DSLR cameras mounted on an arm to capture an object placed on a turntable from different angles.
