Abstract

The invention relates to the technical fields of artificial intelligence, computer vision, and aerial image processing, and in particular to a method for uniform light processing of aerial images of photovoltaic power plants based on machine vision. Including: using drones to take a large number of visible light images with overlapping parts; extracting feature points of the images to be stitched for image registration, establishing a mathematical transformation model for the same coordinate transformation, and stitching the images to be stitched to generate a larger canvas image. The larger canvas image is fused to obtain the spliced ​​and reconstructed ground image of the photovoltaic power station; the image of the photovoltaic power station area is semantically segmented to obtain the semantic category in the image, and a binary image with different semantics is obtained; the binary image with different semantics and the original Multiply the images to obtain the visible light images of each semantic and calculate the brightness standard deviation image; build a loss function to optimize the neural network, obtain the optimized background image, and perform uniform light processing on the spliced ​​and reconstructed photovoltaic power station image according to the optimized background image .

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence, computer vision and aerial image processing, in particular to a method for uniform light processing of aerial images of photovoltaic power plants based on machine vision. Background technique [0002] Due to the large area of ​​the photovoltaic power station, the acquired image cannot form a complete image when aerial photography is carried out under the condition of large focal length. The existing technology is a complete image obtained by splicing a large number of aerial images. Affected by the acquisition time of optical aerial remote sensing images, external lighting conditions and other internal and external factors during shooting, there are different degrees of color differences in the images of photovoltaic power plants, which will affect subsequent image processing or other factors to varying degrees. Effects of using images in image engineering applications. Therefor...

Problems solved by technology

[0003] There are often multiple problems such as inconsistent brightness, hue, and contrast between images, and a single dodging algorithm is difficult to solve all problems

When dealing with large-scale images, when the main features in the image are inconsistent, the dodging effect of the dodging algorithm is not ideal. After dodging, it is difficult to achieve basically the same color tone and brightness

For spliced ​​images, the uneven distribution of hue and contrast is irregular, and the brightness distribution is discontinuous. At present, there are relatively few studies on such problems. Therefore, more in-depth research is needed on the uniform light processing of spliced ​​images.
