Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The resolution of the depth image obtained by the active light device is low and there is a lot of noise interference. Compared with the color image, the edge structure of the depth image is simpler. The interpolation method can be used to increase the resolution of the depth image and realize the depth image enhancement. . If the classic interpolation algorithm is directly used to process the entire depth image, it is easy to cause texture copy and edge blurring in the non-edge area of ​​the depth image, and at the same time, in order to avoid the problem of excessive smoothing of the edge of the depth image. Therefore, the present invention uses the neighborhood difference method to obtain the maximum depth difference in the n...

Abstract

The invention provides a depth map enhancement method blending a high-resolution color image. The method comprises the following steps: firstly, calculating the maximum depth difference of pixel points in a neighborhood according to a neighborhood difference method; dividing a low-resolution depth image into an edge region and an non-edge region; conducting secondary dividing on the non-edge region by utilizing local neighborhood variance; obtaining depth values, corresponding to a mapping point, of a point to be interpolated by utilizing a mean interpolation method and a three-dimensional convolution interpolation method respectively; sampling a high-resolution image on the low-resolution depth image based on the principle of bilateral filtering by taking the high-resolution color image as a reference image; obtain the depth values, corresponding to the mapping point, of each pixel; and finally outputting a depth enhancement image subjected to interpolation processing. The method can not only effectively remove noise interference, reduce the complexity of a depth enhancement algorithm, but also maintain the integrity of image edge information.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a depth image enhancement method, in particular to a depth image enhancement method for fusing high-resolution color images. Background technique [0002] A depth image is an image used to describe the geometric information of a 3D scene, and each pixel in the image represents the distance from a point in the 3D scene to the imaging plane. With the development of computer vision technology, depth information estimation technology has gradually developed into one of the research hotspots in the field of computer vision, and is widely used in navigation system analysis, stereoscopic video generation, virtual reality and other systems. [0003] Currently, methods for depth information estimation are mainly divided into two categories: active light methods and passive light methods. [0004] The active light method is a method to directly obtain the depth information of the 3...
