Problems solved by technology

[0002] Depth information plays an important role in many computer vision applications, such as AR, scene reconstruction, 3D TV-assisted sensors, etc. AR technology can make the real-time world richer, more interesting and more efficient by superimposing rich text and multimedia information. AR The scene has three-dimensional information. By superimposing virtual objects in real-time three-dimensional space, the seamless fit with the real scene is realized. However, the detection efficiency and accuracy of the image recognition technology that the existing AR technology relies on remain the same. The failure to meet the requirements of most application scenarios directly leads to the fact that AR technology can only be applied in some specific scenarios, which greatly limits the limitations of the use of AR technology, and the data needs to be preprocessed in the actual visual image application. Filling empty pixels and smoothing image noise, most of the existing technical solutions are based on RGB images and their corresponding edge information as a guide for bilateral filtering, rarely considering the scene where depth discontinuity is invisible in RGB, and cannot effectively solve this scene At the same time, over-enhancement of the image is likely to cause blocky discontinuity in the image, and the edge of the target is blurred after the depth image is enhanced. Therefore, we propose a depth image enhancement processing method and device.
