Techniques of depressing image noise in laser imaging tracking system

Abstract

Abstract:

Laser imaging tracking system is a potential way of tracking dark target in distance especially in space, but target image under the illumination of laser is modulated by the laser speckle and it will affect the identification and orient precision of target. Firstly, analysis of the statistical characteristic of laser imaging is given, and then, a combined method depressing the image noise that utilize gray level linear transformation, median filtering and Lee filtering acting on the original image in turn is provided. The results indicate that the noise coefficient is down to 0.22 from 0.67, and edge-preserving degree is up to 0.96, respectively, and it makes a necessary basis for the following image processing.

Key words: image processing, noise depression, combined numerical filter, laser speckle
