Problems solved by technology
Therefore, for images taken at different positions and angles in general scenes, projection transformation can no longer express their positional relationship
[0003] In practical applications, the shooting of the same scene is usually done by different cameras at different angles and positions, which makes the newly captured image compared with the previously captured image, which may have different camera setting parameters, inconsistent object depth in the scene, etc. situation, of course it is impossible to use a projective transformation for registration

The invention provides an image registration method and a device, and belongs to the field of image processing. The method comprises the steps of extracting the feature points of a source image and the feature points of a to-be-registered image and matching the feature points of the source image with the feature points of the to-be-registered image to obtain the matched feature points of the source image and the to-be-registered image; extracting the linear segments of the source image and the linear segments of the to-be-registered image and matching the linear segments of the source image with the linear segments of the to-be-registered image to obtain the matched linear segments of the source image and the to-be-registered image; with the matched feature points and the matched linear segments as a constraint condition, conducting the deformation treatment on the to-be-registered image to enable the matched feature points of the to-be-registered image to be consistent with the matched feature points of the source image in position and the matched linear segments of the to-be-registered image to be consistent with the matched linear segments of the source image in direction after the deformation treatment, and adopting the deformed image as a registered image. Based on the above method, the registration rate of the image registration is effectively improved.
Description
technical field [0001] The present invention relates to the field of image processing, in particular to an image registration method and device. Background technique [0002] Image registration is an important research problem in computer graphics and computer vision, and a key technology in image stitching and fusion. Image registration is the process of matching and superimposing two or more images acquired at different times, different sensors or under different conditions. For example, the images to be registered are captured by the same camera rotating around the focal point in one direction. By matching the feature points in the overlapping areas, these images can be approximately transformed to the same imaging plane by using projective transformation. In general, when the position of the camera and the shooting angle are changed arbitrarily, only when all objects in the scene are in the same plane can projection transformation be used to represent the positional rel...
