Embodiment Construction

[0035] Such as figure 1 As shown, in the present invention, a light source lens 2 is added between the light emitting diode 1 and the flow chamber 3, and the light emitting diode 1 is 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-fo...

Abstract

The invention relates to a red-tide living thing image automatic identifying device and method, provided with a LED, a light source lens, a mobile room, an objective, a depth of focus lens and a camera; the LED is at the focus of the light source lens, the mobile room is between the light source and the objective, and the depth of focus lens is between the objective and the camera. The identifying method: obtaining image, preprocessing, detecting object, separating image, obtaining image feature, classifying and identifying object, and outputting result. It adopts a far-focus objective, adds an operating space between the mobile room and the objective, giving a development space to the mobile room, and increases the application range of the apparatus. It can automatically analyze images, heightening automation degree of the apparatus, and meets the request for field monitoring red-tide living things, hopeful to implement real-time monitoring the generating and disappearing course of the red tide, and on this basis, provides a precaution to the danger degree of the red tide.

Description

technical field [0001] The invention relates to an image recognition device and a 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 Due to the particularity of the source of the acquired image, the red tide biological image automatic identification device and its identification method can realize on-site monitoring of 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, envi...
