Problems solved by technology

[0005] To expand the dynamic range of aerial images, a low-cost solution is needed to solve the relative motion between the target and the camera. Choosing multi-exposure fusion can save costs. At the same time, adding an image registration and correction module before the image fusion module, more It is good to solve the problem of displacement between aerial images, and is used to expand the dynamic range of spatial images

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and implementation steps.

[0018] The design scheme of the system of the present invention is as figure 1 As shown, it is mainly divided into three parts: data loading stage, image processing stage and system software design. Among them, the data access stage adopts the database entry method, which can effectively ensure convenient data storage and fast reading speed; the image processing stage completes all image editing functions, including image registration module, image correction module, and image fusion module; the system software design comes from Complete all interface functions, make the operation steps visualized and easy to operate.

[0019] 1. Data access stage:

[0020] It is mainly to read the multiple image information and other related data of the same shooting target captured by the UAV after performing the flight mission, and transmit it to the syste...

Abstract

The invention discloses a multi-exposure fusion system based on aerial images. The system includes image registration, image correction, and image fusion functional modules: the registration module includes extraction of image feature points and image matching; the correction module includes image correction and cropping ; The fusion module adopts the multi-exposure image fusion algorithm for image fusion. The present invention adopts several images with similar locations for aerial photography, which changes the drawbacks of previous multi-exposure fusion images that need to be photographed at fixed points, realizes the improvement of the dynamic range of the image with relative displacement between the imaging device and the imaging target, and can eliminate the displacement error during aerial photography , which effectively expands the dynamic range of aerial images and is better applied to aerial images. At the same time, through the software operation, the visual operation of the aerial image fusion is guaranteed for the user, and the user can feel the efficiency and convenience of the image fusion.

Description

technical field [0001] The invention relates to a multi-exposure fusion system based on aerial images, and relates to the fields of multi-exposure fusion, image registration, space aerial images, development system construction and the like. Background technique [0002] In recent years, many companies and individuals at home and abroad have combined drone technology into their own fields. It is of great significance to use drone technology to detect and shoot environments such as oceans, cities, forest farms, pastures, and farmland. However, direct use of remote sensing images from drones will result in partial overexposure or loss of details, so it is necessary to expand the dynamic range of aerial images. [0003] In the field of high dynamic range (HDR) image generation, the most widely used methods at home and abroad are the method of directly acquiring HDR images by hardware photosensitive elements and the method of multi-exposure image fusion. These two methods have ...
