Automatic distinguishing method for image of red tide organism

Abstract

Present invention provides red tide biologic image automatic identification method and device. It contains Light Emitting Diode, light source lens, field lens, depth of field lens, and camera. Said Light Emitting Diode is located at light source lens focus, flow located between light source lens and field lens, depth of field lens located between field lens and camera. Its steps are obtaining image, pretreatment, target detection, image segmentation, image features obtaining, target classification identifying, and result outputting. Symmetrical background light source can be generated through lens processing, which is favor of obtaining good image effect. It adopts long-focus field lens, increasing operating space between flow room and field lens, enhancing instrument application range. Said invention also can proceed automatic analysis to image, enhancing instrumental automaticity and satisfying red tide biologic field monitoring requirement.

Description

technical field

[0001] The invention relates to an image recognition method, especially to distinguish red tide organisms from plankton groups in water bodies by using image features, and then identify them according to their characteristics, so as to realize the identification of red tide organism species, and because of its acquisition The particularity of the source of the image can realize the red tide biological image automatic identification device and the identification method of the on-site monitoring of the red tide organisms. Background technique

[0002] Red tide is one of the common and important disasters in my country's coastal waters, and it is an important project for marine ecological environment monitoring. Since the 1970s, the frequency of red tides in my country has increased by three times every ten years. In 2002, there were 79 red tide events, with a cumulative area of ​​more than 10,000 square kilometers, causing serious ecological, resource, environm...
