Embodiment Construction

[0027] The specific steps of the real-time synthetic aperture perspective imaging method based on multi-source data fusion of the present invention are as follows:

[0028] 1. Collect scene depth information and color information.

[0029] In this part, the Kinect somatosensory camera is used to obtain the depth information and color information of the scene, and the imaging target and the depth value of the imaging target in the depth image are determined according to the first frame image collected. Determine the virtual viewing angle corresponding to the first frame as the virtual reference viewing angle, and continue to collect video data as data input.

[0030] 2. Obtain the marking information of the foreground occluder and the marking information of the unknown depth area.

[0031] Assuming that the depth of the target is d, the area whose depth is less than d-3σ and greater than zero is marked as the foreground occluder area, where σ can be adjusted according to the d...

Abstract

The invention discloses a real-time synthetic aperture perspective imaging method based on multi-source data fusion so as to solve the technical problem of poor real-time performance of a conventional synthetic aperture imaging method based on energy minimization pixel labeling. The technical scheme is characterized in that: information of the depth where a selected target is located is obtained by utilizing multi-source data and based on a first frame depth image; with target depth range analysis being combined, foreground pixel points and depth-unknown pixel points of a current image are marked; then, the probability of the pixel points belonging to the target in a current color image is obtained by utilizing mark information of the scene and target subordinating degree function, and visual angle attitude information of the current frame is obtained; and at last, based on the obtained target existence probability of the current frame and camera attitude, a synthetic image of the current frame is obtained, and meanwhile, synthesis results are obtained in real time with the generated synthesis results and useful information serving as input information of the next frame and through an iteration method. After test, with the real-time synthetic aperture perspective imaging method, clearer synthetic images can be obtained and meanwhile, the processing effect of real-time processing is achieved.

Description

technical field [0001] The invention relates to a real-time synthetic aperture perspective imaging method, in particular to a real-time synthetic aperture perspective imaging method based on multi-source data fusion. Background technique [0002] Synthetic aperture perspective imaging technology based on camera array is an important research topic in the field of computer vision, and it has a wide range of applications in hidden target imaging, detection, recognition and tracking, and free depth viewpoint imaging. The current synthetic aperture perspective imaging methods mainly include: plane + parallax-based synthetic aperture imaging method and energy minimization-based pixel-labeled synthetic aperture imaging method. [0003] The document "Synthetic Aperture Imaging using Pixel Labeling via Energy Minimization, PR, 46(1): 174-187, 2013" discloses a synthetic aperture imaging method based on energy minimization pixel labeling. Different from the traditional synthetic ape...
