Problems solved by technology

[0005] In the traditional parallel binocular stereo vision transmission process, the direct transmission of the left view and the right view has a large amount of information, occupies a large amount of transmission bandwidth resources, and has low transmission efficiency. The present invention proposes a stereoscopic image generation method based on a depth map.

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] A stereoscopic image generation method based on a depth map proposed by the present invention is based on a parallel binocular stereoscopic vision model.

[0038] Firstly, the left view or right view collected by the parallel binocular stereo imaging system and its corresponding depth image are given, and the given depth image is preprocessed.

[0039] Due to the influence of the device itself and the surrounding environment during the acquisition process, the depth image usually contains a lot of holes and noise. If it is used directly, it will affect the subsequent effect, so the depth image needs to be preprocessed. The specific process is to first filter the depth image with morphological filtering, and then perform secondary filtering on the depth image after the first filtering with bilateral filtering.

[0040] Morphological filt...

Abstract

The invention discloses a three-dimensional image generating method based on a depth map, and aims to solve the problems of large information quantity, high occupancy of transmission bandwidth resources, low transmission efficiency and the like due to direct transmission of a left view and a right view in a conventional parallel binocular three-dimensional visual transmission process. The three-dimensional image generating method based on the depth map comprises the following steps: firstly, preprocessing a depth image by morphology and bilateral filtering to reduce cavities in the depth image; secondly, providing a viewpoint image to generate another viewpoint image through restoration in conjunction with the depth map according to a principle of a binocular parallel three-dimensional imaging system; and finally, filling up cavity points of a restored view according to depth information and original view information to obtain a final left-right view three-dimensional image pair. Compared with direct transmission of the left view and the right view in a conventional method, the three-dimensional image generating method has the advantages of smaller information quantity of the depth map than that of an ordinary image, higher transmission speed and efficiency of the depth image, low occupancy of a transmission bandwidth, and capabilities of saving resources and increasing efficiency.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method for generating a stereoscopic image based on a depth map. Background technique [0002] Stereoscopic imaging is becoming more and more popular as technology advances in the field of computer vision. Stereoscopic images can enhance the sense of reality and immersion of the scene in the image, and have been widely used in the fields of culture and entertainment, medical treatment, military simulation, engineering exhibitions, and education, and have become a hot field of scientific research and industry in various countries. [0003] Stereoscopic image-related technologies mainly involve three aspects: stereoscopic image generation, stereoscopic image display and stereoscopic image perception. In the traditional parallel binocular stereoscopic imaging system, the stereoscopic image is generated by simultaneously transmitting the captured left view and right view. This metho...
