Abstract: At present, the platforms for home furnishing are facing the following issues: manual operation for indoor scene modeling is demanded in great level, much artificial intervention for home furnishing is needed, the calculation speed of algorithm for automatic arrangement is not ideal. Aiming to these problems, this paper takes bedroom as example, oriented to virtual-real fusion between cuboid model from real room image and virtual furniture models, uses the technique of image based rendering TIP (tour into picture) to convert 2D room images to 3D cuboid model, to achieve the compatibility and dimension consistency with 3D furniture model. Then, in the cuboid model, the furniture model will be automatically arranged with an algorithm based on energy distribution in placement field. Firstly, determine the sequence of furniture to be located, and then initialize the energy distribution of the placement field. After that, determine the locations of furniture by order, and update the energy distribution dynamically for the next furniture arrangement. Finally, calculate the tour area and visual orientation based on the energy distribution. The experiments show that the algorithm can achieve faster and better automatic arrangement results for different sizes and different furniture combinations, generate a good tour plan, and realize the virtual-real fusion.
