A reconstruction method of three-dimensional texture mapping and imaging based on phase-assisted system is proposed, which can map the captured texture images around objects onto the surface of the geometric model to achieve the fusion of texture color of geometric surfaces. The texture mapping optimization function is established, and the mapping between the target object and the texture image is optimized. The texture fusion processing is used to ensure the fidelity of the target object texture to the greatest extent, and the three-dimensional texture reconstruction of the object is realized. The locally missing target model and the uncollected local texture are also repaired, and the natural transition of the three-dimensional texture surface is realized, thereby ensuring the integrity and consistency of the target model texture. The experimental results of different types of physical objects prove the feasibility and effectiveness of the proposed algorithm.
