This invention relates to a method for stitching backlit images of a stator annular aperture, comprising: focusing an industrial camera on the stator annular aperture; determining the required number of local backlit images and planning the acquisition position for each local backlit image; acquiring each local backlit image using the industrial camera according to the planned acquisition position; determining the corresponding image stitching matrix according to the selected image stitching method; and generating a panoramic backlit image of the stator annular aperture based on the image stitching matrix. This invention also relates to a stitching device for backlit images of a stator annular aperture. The purpose of this method and device for stitching backlit images of a stator annular aperture is to solve the problem of difficulty in stitching backlit images of apertures.

The application discloses a kind of based on digital human segmentation MRI image splicing and fusion method, comprising: the MRI data of different parts of human body obtained by nuclear magnetic resonance scanning is first registered after being preprocessed such as noise reduction, using the resolution, orientation etc. of reference image and floating image after registration, further realize the transformation of floating image between image coordinate system and world coordinate system, simultaneously based on trilinear interpolation interpolation and operation in the above spatial transformation process.The application realizes the seamless fusion of the three-dimensional image to be spliced in high and low frequency direction, effectively utilizes image high and low frequency component information.The application not only simplifies the two-stage image splicing and fusion process of traditional splicing method, i.e.fusing overlapping area first and then splicing non-overlapping area, and greatly improves the overall splicing and fusion accuracy of segmented MRI data.

The application provides a UAV hyperspectral image alignment method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a first image of a target aerial photography area photographed by a UAV when flying along a first flight strip; acquiring a high-resolution satellite image of the target aerial photography area greater than the range of the first flight strip at the same photographing time as the first image, and acquiring a second image according to the high-resolution satellite image; taking the same position points of the overlapping parts between two adjacent hyperspectral images in the first image as first control points; taking the same position points of the overlapping parts between each hyperspectral image in the first image and a simulated hyperspectral image in the second image as second control points; for each hyperspectral image in the first image, aligning the first control points of the hyperspectral image with the first control points of a second hyperspectral image, and aligning the second control points of the hyperspectral image with the second control points of a target simulated hyperspectral image. The application can improve the accuracy and stability of UAV hyperspectral image splicing.
