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 use bilateral filtering to perform secondary filtering on the depth image after the primary filtering.

Abstract

In the traditional parallel binocular stereo vision transmission process, the direct transmission of the left view and right view has a large amount of information, occupies a large amount of transmission bandwidth resources, and has low transmission efficiency. The invention discloses a method for generating a stereoscopic image based on a depth map. Firstly, the depth image is preprocessed by using morphology and bilateral filtering to reduce holes in the depth image; Given the viewpoint map, another viewpoint image is restored; finally, the restored view is filled with the depth information and the original view information to obtain the final stereoscopic image pair of the left and right views. Compared with the direct transmission of the left view and right view in the traditional method, the information volume of the depth image in the present invention is much smaller than that of the ordinary view, and the transmission speed and efficiency of the depth image are higher, and the transmission bandwidth is small. It can save resources and improve 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...
