Abstract

In the process of laser pointing, there will be laser speckle phenomenon, which affects the image observation effect. In this paper, a laser point de-fuzzy method was proposed, which provided a new idea for reducing the influence of laser speckles. Firstly, the background was stitched by affine transformation of the image, and then, the location information of laser point was acquired. Finally, the new optical point was added to corresponding position in the background by calculation. The video with expected clear laser point and no color difference background is obtained. The experimental results show that the background color difference caused by the optical filter has been eliminated, and the new light spot is clearly mapped in the correct position, which achieves the effect of removing the light spot fuzzy and accurately tracking the laser point.
