A method for obtaining panoramic images with coded aperture camera

Abstract

The invention discloses a method for obtaining a panorama by using a code aperture camera. Distant-view panoramas that all parts are clear can be obtained by utilizing the method. The method comprises the following steps of: shooting a view by using the code aperture camera; calculating so as to obtain the sizes of point spread functions of points in shot images; clarifying the images by utilizing the corresponding relationship between the sizes and the depths of the point spread functions and utilizing a deconvolution algorithm; and splicing the clarified images so as to obtain the panorama. By utilizing the method, the splicing mistakes caused by shielding articles in the view are reduced when the images are spliced, and the problem of image blurring caused by the inconsistency of field depths in shooting when the panorama is spliced is avoided. According to the method, the code camera is adopted to acquire the view, so that the requirement on equipment is relatively low, and no extra depth acquiring equipment is used when obtaining an optimal panorama; and the method is simple and convenient in shooting process and easy to implement and popularize.

Description

technical field [0001] The invention relates to a panorama mosaic method, in particular to a method for acquiring a panorama with a coded aperture camera. Background technique [0002] The panorama can greatly expand the shooting range of the camera, bring people a visual shock and an immersive feeling, and is an important means to improve people's immersion in the virtual environment. The classic panorama stitching discusses the selection of image key points, image registration, calibration, and mutual fusion in the stitching process. The main work is to stitch and fuse the obtained photos directly to present the original scene image acquired during shooting. , but does not deal with issues such as stitching when there are close-range objects in the panorama during stitching and defocus blur in non-focused areas. [0003] When the foreground object exists in a perfect scene, it will block part of the scene, and even cause problems with stitching, making the original perfec...

AI Technical Summary

Problems solved by technology

[0008] 1. When presenting the original scene image acquired during shooting, problems such as stitching when there are close-range objects in the stitching panorama and defocus blur in the non-focused area are not dealt with

[0009] 2. When taking a panorama, objects that are very close to the surroundings may appear in the lens, and objects in the middle distance in front of the background may also appear in the lens, and these objects may be static or moving. It is not possible to get a panorama with a completely clean background by taking a photo
