摘　　要：介绍了一种海洋赤潮生物监测荧光成像系统,该系统的背景光源为海洋赤潮生物监测荧光成像系统的重要组成部分,赤潮生物监测荧光成像系统背景光源选择是否合理将直接影响着藻类成像清晰度,由于各种赤潮藻含有不同的特征纹理,其纹理特征将决定是否能准确识别出藻类并对其进行分类,进而影响到对赤潮的准确预报。为了解决赤潮藻图像的清晰度等问题,作者利用自行设计的荧光成像系统,对不同成像光源的成像效果进行了分析和比较。实验证明,近红外光源可以有效地获得清晰的藻类纹理信息,使得后继的图像处理工作更加容易,从而解决了藻类图像暗黑以至于图像处理起来较为困难等问题。A real time algae fluorescence imaging system is introduced in the present paper.The light source is an important part of algae fluorescence imaging system.Algae image definition is directly influenced by the light source of red tide monitor system,and different red tide algae has different texture character,which decides the nicety of recognizing harmful algae and category.For solving the definition of algae imaging,the authors analyzed and compared images with different light sources using the fluorescence imaging system designed ourselves.The result shows that near infrared light source can effectively show algae texture,so that the image processing is more effective and easier.
