AI Technical Summary

Technical Problem

Existing power line inspection image dehazing technology fails to effectively distinguish the differences between equipment and background when processing foggy images, resulting in low defect identification accuracy and slow processing efficiency.

Method used

An imaging distance-based layering method is adopted to accurately distinguish key equipment from the background through depth information estimation and imaging distance layering. Differentiated dehazing strategies are used to process images at different levels, including accurate dehazing and fusion of detail layer, transition layer and background layer.

Benefits of technology

It improves the accuracy and efficiency of defect identification, reduces the consumption of computing resources, and outputs high-quality inspection images to support the identification of defects in power equipment.

Abstract

The application discloses a power inspection image defogging method and system based on imaging distance layering, belongs to the technical field of power inspection image defogging processing, and realizes accurate distinction of key equipment and background by depth information estimation and imaging distance layering on a fog-containing original inspection image, thereby avoiding the disadvantages of a traditional defogging method that adopts a global and unified processing mode, adopting different defogging strategies for different layers of the layered image, not only preventing the key equipment from being disturbed by excessive enhancement, but also not needing to restore invalid details of the background, thereby reducing the loss of computing power while ensuring the defogging effect, improving the effective information density, and guaranteeing the inspection image processing efficiency and visual authenticity, providing high-quality image support for power equipment defect identification, and fully considering the difference between the equipment and the background.
