Embodiment Construction
[0042] In the following detailed description, numerous specific details of the disclosure are set forth by way of example in order to provide a thorough understanding of the relevant disclosure. It will be apparent, however, to one of ordinary skill in the art that the present disclosure may be practiced without these details. It should be understood that the terms "system", "device", "unit" and / or "module" used in the present disclosure are used as a means of distinguishing between different parts, elements, sections or assemblies at different levels in a sequential arrangement. method. However, these terms may be replaced by other expressions if the same purpose can be achieved by other expressions.
[0043]It will be understood that when a device, unit or module is referred to as being "on," "connected to" or "coupled to" another device, unit or module, it can be directly on the other device, unit or module. connected or coupled to or communicate with other devices, units...

This embodiment discloses a method and device for stitching and modeling panoramic images, which relate to the field of computer vision. Wherein, the method includes: continuously accumulating the first matching feature point pair between the non-wide-angle image and its corresponding wide-angle image, and generating the first homography matrix according to the first matching feature point pair until the first accumulation End condition: continuously accumulate the second matching feature point pairs between non-wide-angle images, and project the feature points in the second matching feature point pairs into the wide-angle coordinate system where the corresponding wide-angle image is located according to the first homography matrix , screening the second matching feature point pairs that meet the preset conditions to form a total non-wide-angle matching feature point pair, until the second accumulation end condition is met; the second homography matrix is generated according to the matching feature point pair in the above; according to the The second homography matrix acquires the parameters corresponding to the non-wide-angle camera to complete the panoramic image stitching modeling.
Description
technical field [0001] The present disclosure relates to the field of computer vision, in particular to a method and device for stitching and modeling panoramic images. Background technique [0002] In the prior art, the panorama mosaic technology usually uses feature point matching between sub-images as a basis to automatically construct the geometric structure of the panorama. This approach achieves very high quality in a variety of different applications. [0003] However, when this method models all the cameras involved in stitching, each sub-camera needs to have sufficient number and quality of matching feature point pairs with other sub-cameras whose fields of view overlap. If the number or quality is insufficient, there will either be partial Either the camera field of view does not appear in the stitched panorama, or poor stitching quality occurs. When using this method to model, it is often necessary to manually select and process the scene (such as placing artifi...
