3D roam method and system

Abstract

The invention discloses a 3D roaming method and a system. The 3D roaming method comprises the following steps: acquiring an RGBD image of a target space and establishing a three-dimensional texture model of the target space; Recognition of reflective surfaces in RGBD images or 3D texture models; according to the relative positional relationship between the viewpoint and the reflective surface, thereflective image of the reflective surface is calculated. By the method and system as described above, the reflective image can be filled into the reflective surface in real time and the correct reflective image can be presented, the whole process is simple and easy to operate, and the 3D model is more realistic because the 3D model is filled in real time during the 3D roaming, and the immersioneffect of the 3D roaming is further improved.

Description

technical field [0001] The present invention relates to the technical field of image data processing, in particular to a 3D roaming method and system. Background technique [0002] Three-dimensional models have been used in various fields, and have been widely used in medical industry, film industry, video game industry, scientific field, real estate construction industry and other application fields. At present, there are roughly three methods for three-dimensional modeling of objects: One is to use 3D software to model; the second is to use pictures or videos to model; the third is to use equipment to scan and model; the first two are due to the lack of depth information of the real scene, resulting in a lack of realism in the scene. The latter is currently more popular to use a 3D scanner to scan the spatial structure at 360° to obtain a panoramic image with depth information, which has the advantages of immersive roaming and human-computer interaction, while consumer-gra...

Problems solved by technology

But the current problem is that, for example, in real estate, since mirrors and other reflective surfaces that can reflect objects are generally installed in houses, when scanning machines are used to scan the entire interior of the house, the reflective surfaces often show different images such as scanning machines or people. Necessary image, on the other hand, the 3D model does not present the indoor reflection image that should appear on the reflective surface, which will affect the customer's understanding of the house situation, and there are also problems with the authenticity of the 3D roaming, but the existing technology does not solve this problem Do detailed research, therefore, restore the correct real reflective image that should be presented by the reflective surface based on the viewing angle of the user, and further improve the texture and robustness of the 3D model are currently facing problems
