Research of image processing technology based on seamless splice and depth measurement

The detection of artillery inner-chamber flaw is an important task in artillery development, production and maintenance. Owing to the special structure and lathy space of gun, the processing of flaw images has many difficulties. In this paper, aiming at the problem of single image can not show a larger flaw integrally, the improved splice method based on log-polar coordinate mapping and phase correlation was employed, the seamless splice of flaw images was realized; Aiming at flaws such as rifling rib cracks, rush concaves and erosion pits influence the security of artillery seriously, technology based on multi-baseline stereo imaging was employed and depth measurement was realized in a creative way, the depth information of serious flaws was provided. Through the application of above technologies, the detection of artillery inner-chamber flaw is more perfect than ever.
