Picture comparison and identification method for common algae

The invention provides a picture comparison and identification method for common algae. Firstly, an algae information base is constructed, algae information is subjected to classification management according to categories, target pictures are obtained for comparison and identification, an electronic ocular lens is used for photographing all algae species, algae images are preprocessed and then stored in computer terminal equipment, reproduction of the algae species information is guaranteed, and therefore the algae identification accuracy can be improved; and unknown algae species can be conveniently determined by utilizing the algae characteristic database and the algae picture library, so that the algae identification work can be more accurately realized. 本发明提供一种常见藻类的图片对比鉴定方法，先构建藻类信息库并将藻类信息按照类别进行分类管理，获取目标图片进行比对鉴定，利用电子目镜对各藻种进行拍照，藻类图像经过预处理后存入计算机终端设备中，保证了藻种信息的再现，从而可提高藻类鉴定准确性；利用藻类特征数据库和藻类图片库可方便地确定未知藻种，从而能够更准确地实现藻类的鉴定工作。
