Problems solved by technology

[0005] In order to solve the problem that when the terminal obtains the initial spliced ​​image by projecting the image only according to the main pose parameters, because the main pose parameters may not be applicable to the entire image, the overlapping areas of the initial spliced ​​image obtained by the terminal cannot achieve good overlap. The problem of poor effect, the embodiment of the present invention provides an image stitching method and device

Embodiment Construction

[0033] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0034] Firstly, some nouns involved in this article are introduced.

[0035] Depth plane: refers to the plane where the object in the image is located in the actual scene. for example: figure 1 In the shown image, the plane where the character's head 11 is located is the depth plane 11'; the plane where the computer's back 12 is located is the depth plane 12'. Usually, in an image, the depths...

Abstract

The invention discloses an image stitching method and apparatus, and belongs to the technical field of image processing. The image stitching method includes the steps: according to a first overlapped area in the current image, determining the main pose parameter of the current image; according to the main pose parameter, projecting the current image to a projection canvas, and obtaining an initial stitched image; in a second overlapped area of the initial stitched image, selecting a local overlapped area, wherein the depth of the depth surface of each object in the local overlapped area is the same; calculating the local pose parameter of the local image area corresponding to the local overlapped area in the current image; and according to the main pose parameter and the local pose parameter, re-projecting the current image to the projection canvas, and obtaining a target stitched image. The image stitching method and apparatus can solve the problem that a terminal projects an image to obtain the initial stitched image only according to the main pose parameter and the main pose parameter may not be suitable for the whole current image, so that the overlapped area of the initial stitched image obtained by the terminal cannot realize good overlapping, and can improve the image stitching effect.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to an image splicing method and device. Background technique [0002] Image stitching technology is widely used in panoramic shooting, space detection, remote sensing image processing, medical image analysis and other fields. Image mosaic technology refers to the technology of seamlessly stitching more than two partially overlapping images to obtain a large format or wide viewing angle image. [0003] An image processing method is provided in the related art, and the method includes: the terminal determines the overlapping area between two images; extracts feature points from the overlapping area of ​​the current image; calculates the first The pose parameters of the camera; according to the pose parameters, the transformation matrix for projecting the current image onto the projection canvas is calculated; through the transformation matrix, the c...
