Description
Technical field
The invention belongs to digital audio-video technical field, and in particular to be directed to the less efficient image method for registering in overlapping region in a kind of video-splicing.
Background technology
The precision of image registration is the key factor for determining video-splicing effect.In video-splicing, general handling process shows for image registration, image co-registration and image.In process of image registration, first to each image zooming-out characteristic point, then the characteristic point to overlapping region is matched, and is finally the parameter that image registration is determined according to the position relationship of the characteristic point pair of matching.But above-mentioned method for registering images registration effect when image includes timestamp to overlapping region in smaller or overlapping region is poor, so as to cause the effect of final video-splicing unsatisfactory.
The content of the invention
The present invention carries out manual intervention to overlapping region by process of image registration, increases the ratio of correct matching double points, improves the precision of image registration.
Technical scheme is as follows：
The less efficient image method for registering in overlapping region is directed in a kind of video-splicing, it is characterised in that：
(1) two field picture for choosing camera to be spliced is initially registered process.Feature point extraction is carried out to image respectively, Feature Points Matching process is shown initial feature point pair matching result；
(2) on initial matching display window, the event pressed to left mouse button and lifted is responded, decision block choosing rectangle frame the upper left corner and the coordinate position in the lower right corner, manually select correct matching characteristic point to be distributed comparatively dense region；
(3) using the characteristic point in selected region to as the characteristic point pair after screening, as the input of secondary registration, completing process of image registration；
(4) inside and outside parameter according to camera carries out image co-registration, obtains final image mosaic result.
The present invention is for overlapping region area is small, characteristic point carries out manual intervention to the initial registration result of few image and chooses the mode that correct registration region realizes secondary registration, the accuracy of registration parameter estimation can be significantly improved, ideal splicing result is finally obtained.
Specific embodiment
Below by taking two video-splicings of monitoring camera as an example, the principle and necessity of simple declaration manual intervention registration.The a certain frame of the video that two monitoring cameras are photographed, registration parameter is calculated with the registration of the image pair.But in the image pair, overlapping region has that area is small, characteristic point to it is few the features such as, simultaneously because two positions of camera, the features such as timestamp is basically identical, camera head monitor region has great similarity, causing to have a certain amount of error hiding pair and pseudo- matching being right.Choose correct matching secondary registration carried out to the region relatively concentrated by artificial in preliminary matches result, can effectively improve correct matching to ratio, so as to realize to the accuracy registration with the image that overlapping region area is small, characteristic point is to the feature such as few.
Implement process as follows：
(1) two field picture for choosing camera to be spliced is initially registered process.Feature point extraction is carried out to image respectively, Feature Points Matching process is shown initial feature point pair matching result；
(2) on initial matching display window, the event pressed to left mouse button and lifted is responded, decision block choosing rectangle frame the upper left corner and the coordinate position in the lower right corner, manually select correct matching characteristic point to be distributed comparatively dense region；
(3) using the characteristic point in selected region to as the characteristic point pair after screening, as the input of secondary registration, completing process of image registration；
(4) inside and outside parameter according to camera carries out image co-registration, obtains final image mosaic result.
