Problems solved by technology

In the process of 3D reconstruction, if the existing stitching method is used in the image stitching stage, although the stitching effect can barely meet the demand, the time required is too long, which is difficult for applying chips to products such as smartphones. The price / performance ratio is always unsatisfactory

Abstract

The invention provides an image stitching method for light field imaging, and relates to the technical field of image stitching. The image stitching method for light field imaging includes the following steps: 1) inputting images to be stitched; 2) constructing a scale space, and extracting ORB characteristics from the images to be stitched; 3) performing characteristic matching by means of a BBF(best-bin-first) algorithm (a threshold is set as 0.6 in the description); 4) removing error matching points by using an RANSAC (random sample consensus) algorithm, and calculating a transformation matrix H (the invention selects 4 pairs of matching points to calculate the transformation matrix H, and H is a 3*3 matrix); 5) fusing the images by using a weighted average method to stitch the two images into one image; and 6) outputting the stitched image. The image stitching method for light field imaging adopts a characteristic-based registration method, uses an image matching strategy based onthe ORB characteristics, fully utilizes the superior performance of the ORB algorithm, and in the image fusion part, fuses the images by the means of the weighted average method.

Description

technical field [0001] The invention relates to the technical field of image stitching, in particular to an image stitching method applied to light field imaging. Background technique [0002] In the research of light field camera chip algorithm, the research of 3D image reconstruction technology based on light field imaging is the top priority. In the process of 3D reconstruction, if the existing stitching method is used in the image stitching stage, although the stitching effect can barely meet the demand, the time required is too long, which is difficult for applying chips to products such as smartphones. The price / performance ratio is always unsatisfactory. Therefore, it is very urgent to find a mosaic algorithm with good effect and high real-time performance to effectively improve the performance of the product. Contents of the invention [0003] The image splicing method applied to light field imaging provided by the present invention reduces the image splicing tim...
