Research on Infrared Temperature Measurement Image Enhancement Technology of Transmission Line

It is one of the important means to ensure safety transmission line and its equipment realize rapid identification accurate diagnosis visual defect fault points line. In this paper, an adaptive infrared image enhancement algorithm proposed based on research features various algorithms. The first filters remove random noise improve signal-to-noise ratio image; then, histogram analysis image, adaptively selects upper lower thresholds gray histogram, uses segmentation divide into three parts: target, target background aliasing, background. Finally, through distributions, can extract image. suppression are realized. By comparing effect before after enhancement, it proved that has strong practicability.
