During the inspection process of transmission line using UAV (Unmanned Aerial Vehicle), the visible light image obtained by the drone is stitched to obtain a panoramic view of the transmission line inspection area, which can be used as a base map for power inspection, thus providing data support for power channel environmental monitoring. However, in practical tests, due to the influence of cloud cover and non-uniform light distribution, shadows will be left on the generated splicing images, which will affect the image recognition. In order to solve this problem, this paper proposes an image homogenization algorithm based on gray histograms, and uses this algorithm to process the stitched images. The experimental results show that the image splicing quality processed by the algorithm is better than the image processed by the fade-in and fade-out method. That is to say the method mentioned in this title has a good application prospect in the field of image mosaic based on UAV.
