MATLAB在数字图像处理中的应用越来越广泛。首先需要对水下激光线扫描系统成像获得的原始试验 数据进行视频及图像处理才能完成对目标信息的重建。然后利用数学形态学方法进行图像处理,去除 图像的背景光噪声。再用直方图均衡实现图像增强。实验结果表明应用MATLAB对图像进行形态 学、直方图调整等方法能够有效消除图像的背景光噪声,提取出目标信息,提高信噪比,对水下激 光成像效果的改善有显著效果。同时,相当于增大了水下激光成像的探测距离。

MATLAB is used more and more widely in digital image processing. First, the original test data obtained from underwater laser line scanning system need to be processed. The mathematical morphology can be used to deal with the underwater laser line scan results. The background light noise can be eliminated effectively. The targets can be extracted from the histogram equalization. The experiment results show that the resolution and SNR are improved, and the quantity of underwater laser line scan image is improved. At the same time, the detection range of underwater laser imaging is increased.
