Embodiment Construction

[0020] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0021] In the embodiment of the present invention, the boundary of the color image is extracted, so as to introduce a boundary mask to obtain a real sharp boundary. Combined with the boundary mask, an improved local bilateral filter is used to process the depth image from multiple presets Set the direction for filling, and finally use the Markov random field model to fuse the filling results of th...

Abstract

The invention is applicable to the technical field of image processing, and provides a depth image processing method and a depth image processing device. The method comprises the following steps: inputting a depth image and a corresponding color image, wherein the depth image and the color image are pre-registered and are of the same size; extracting a boundary image from the color image, and determining a boundary mask based on the boundary image; filtering the depth image in multiple preset directions through a preset filter based on the boundary mask to get corresponding multiple filtering candidate results; and fusing the multiple filtering candidate results into a depth information completion result of the depth image through a Markov random field model. According to the invention, the boundary of the color image is extracted, the boundary mask is introduced, the depth image is filled in multiple preset directions through an improved local bilateral filter, and the filling results of the multiple preset directions are fused into a final information completion result, and thus, the integrity of depth information is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a processing method and device for a depth image. Background technique [0002] Depth information can reflect some important features of a scene or object, such as structure, boundary information, surface shape, etc. In recent years, consumer-level depth cameras have been widely used in research and home entertainment. Products including Kincet and XtionPro play an important role in algorithm vision work such as 3D reconstruction, object recognition, and behavior analysis. [0003] The current depth image technology will lead to the loss of depth information in many image areas. The lack of depth information includes: 1. Small holes caused by estimation errors; 2. Loss of depth information in occluded areas caused by parallax between the infrared camera and infrared projection; 3. The lack of depth information caused by high light or low reflective surfaces ...
