Embodiment Construction

[0035] As shown in Figure 1, the present invention adds a light source lens 2 between the light emitting diode 1 and the flow chamber 3, and makes the light emitting diode 1 located at the focal point of the light source lens 2, so that a relatively uniform background light source can be obtained. The flow chamber 3 is located between the light source lens 2 and the objective lens 4, the depth of field lens 5 is located between the objective lens 4 and the camera 6, and the objective lens is a telephoto objective lens. A far-focus objective lens can be used to obtain a relatively large working distance; an objective lens with a relatively small NA value can be selected to obtain a relatively high depth of field. The large working distance can obtain relatively large operating space, and can also make the flow chamber obtain relatively large development space. And a high depth of field can obtain a clearer image. For most red tide organisms, you can use a 10x far-focus objecti...

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...
