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.
