Problems solved by technology
When using aerial photography equipment to carry out aerial photography measurement of a certain area, since the structure of each small area of the target area is mostly different, when using aerial photography equipment for direct shooting, it is easy to cause some details to be unclear and cannot fully reflect the whole picture of the target area , to distort the photos. At the same time, in the process of photo correction and stitching, it is easy to cause effective stitching due to the problem of near, large, and small, and stitching deviations are prone to occur.

Embodiment 1
[0023] An operation method for automatically correcting and splicing aerial photographs for oblique photogrammetry, comprising the following steps:
[0024] a. Select the target area to be aerial photographed, and select several target points for reference in this area. The selected target points in the target area to be aerial photographed are evenly distributed and related. The target area is divided into several target point areas, and the overlapping area of the original image photos of two adjacent target points exceeds half of a single target point area;
[0025] b. Take images of the surface of structures at each target point through multi-viewpoints to obtain full coverage of structures at each target point area and overlapping image photos. The image photos of each target point area together form the target to be aerial photographed The original panoramic image of the area makes the aerial photography of the target area more fully and comprehensively, can fully refl...

The invention discloses an aerial photo automatic correction and splicing operation method for oblique photogrammetry, and the method comprises the steps of selecting a plurality of target points forreference in a to-be-aerial-photographed target region, dividing the to-be-aerial-photographed target region into a plurality of target point regions, wherein all target points are uniformly distributed and related, and the overlapping area of the original image photos of two adjacent target points exceeds one half of the area of a single target point; then performing aerial photographing on the panorama of each target point area, enabling the panorama of each target area to form the panorama of the target area to be aerial photographed together, so that the aerial photographing of the targetarea is more sufficient and comprehensive, details can be fully reflected, and imaging deviation caused by oblique photography can be avoided, so that a photo finished product can better fit the reality and is not distorted, and the quality of the photo is better; performing panoramic image splicing on a non-planar structure by using images shot from multiple viewpoints, so that the spliced panoramic image can directly measure plane geometrical characteristics such as the length, the width and the area of a target object, and the added value of a photo is higher.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic correction and splicing operation method for aerial photographs used for oblique photogrammetry. Background technique [0002] In the work of photogrammetry, the technique of projectively transforming aerial photographs, eliminating the displacement of image points caused by the inclination of photographs during photography, and normalizing them into images of a specified scale is called photorectification. When using aerial photography equipment to carry out aerial photography measurement of a certain area, since the structure of each small area of the target area is mostly different, when using aerial photography equipment for direct shooting, it is easy to cause some details to be unclear and cannot fully reflect the whole picture of the target area , to distort the photos, and at the same time, in the process of photo correction and stitching, it is ea...
