The embodiment of the present invention discloses an image mosaic method, device, computer equipment and storage medium. The method includes: based on the preliminary registration accuracy, acquiring the reference feature points of the reference image, and the search features of the search image corresponding to the reference feature points point; based on the preset registration accuracy, within the neighborhood of the search feature point, determine the position of the interpolation point with the greatest similarity to the reference feature point to update the search feature point, wherein the preset registration accuracy is higher than the preliminary registration Accuracy; according to the correspondence between the reference feature points and the updated search feature points, the reference image and the feature image are registered to generate a registration image; the stitching in the registration image is eliminated by image fusion to generate a stitching image. It solves the problem that the prior art cannot give consideration to both the image splicing effect and the splicing speed, and achieves the technical effect of not only ensuring the image splicing effect, but also improving the image splicing speed.

The embodiment of the present disclosure discloses a method, a device, and a computer-readable storage medium for stitching house vector graphics. The method includes: determining a plurality of pairs of vector diagrams from the group of vector diagrams of houses conforming to the set spatial layout rules; wherein, each pair of vector diagrams includes two adjacent vector diagrams of houses in the group of vector diagrams of houses; Vector map pair, according to the common element sequence of the two boundary vector direction groups of the two house vector diagrams included in it, determine the reference mosaic strategy of the two house vector diagrams it includes; wherein, the clockwise order of the two boundary vector direction groups On the contrary; use the reference stitching strategy corresponding to all vector map pairs to obtain the overall stitching strategy; use the overall stitching strategy to get the target stitching vector map of the house vector map group. The embodiments of the present disclosure can conveniently realize the overall splicing of the vector diagram group of houses. Compared with related technologies, the embodiments of the present disclosure can improve the splicing efficiency and ensure the splicing effect.

The invention belongs to the technical field of digital image processing, and specifically relates to a method for automatically splicing images by adjusting the height of an X-ray detector, S1, calculating three-dimensional coordinates of joint points; S2, calculating coordinate offsets; S3, positioning initial positions; S4, determining Move the coordinates of the reference point; S5, shifting successively and taking images; S6, image splicing; a method for automatically splicing images by adjusting the height of an x-ray detector provided by the present invention, by detecting the joint points of the human body, the distance between the two images can be known The position and size of the overlapping part can realize the matching and splicing of the two images, and the image splicing is easier.

The invention relates to a bag-of-word-based panoramic picture splicing method. The method comprises: a trained ORB word bag tree is prepared; ORB feature extraction is carried out on an image i in a to-be-spliced image data set, a k is set to be a last key frame inserted into a spliced structural graph, feature searching is carried out on two images by forward indexing and correspondence between the features is established, so that the correspondence of features of the two images is obtained; a homographic matrix between the two images is obtained; with a random sampling maximum likelihood estimation algorithm, a secondary projection error is minimized and an exterior point is eliminated, so that an interior point set of a corresponding image pair is obtained; on the basis of a boundary matrix, an overlap percentage of the images is calculated; overlapping between the corresponding image pairs is calculated, and connection with a previous key frame needs to be established by the homographic matrix when the image i is added into the spliced structural graph as a key frame; a loop is detected; a loop is formed; the homographic matrix is optimized; and fusion of image splicing structural graphs is carried out.

The invention provides a method for splicing aviation multi-pixel parallel scanning images. According to the method, 'dimension plus rotation' transformational models are adopted in geometric transformational models of two adjacent frames, perspective projection models of area-array cameras are not adopted, the method adapts to the geometric transformational models between the adjacent aviation multi-pixel parallel scanning images, and the overall transformation problem between the adjacent images is well solved.
