Plancton double-light path imaging apparatus

Abstract

The invention provides a plankton double light path imaging device, comprising a digital camera, a microscope system, a triangular prism, two plane reflecting mirrors, a hollow lozenge observation pool, a light source and a supporting frame; the triangular prism and two plane reflecting mirrors are fixed on the supporting frame; the two plane reflecting mirrors are respectively arranged at the left side and the right side of the triangular prism; the hollow lozenge observation pool is fixed above the light source; two end surfaces of the triangular prism are plated by a reflecting film respectively; and the microscope system and the digital camera are connected with each other by data transmission wires. The plankton double light path imaging device can photograph a frame image which contains the conformation image information of two different sides of the plankton, and can quickly obtain the images of the plankton of different angles; simultaneously, the plankton double light path imaging device has the advantages of simple structure, convenient execution and the like.

Description

technical field [0001] The invention relates to an imaging device, in particular to a dual optical path imaging device for plankton. Background technique [0002] In the process of automatic identification of plankton images, it is necessary to collect known plankton sample image information, and compare the tested plankton with known sample images to identify and classify plankton species. [0003] At present, optical monitoring methods for plankton, such as digital microscopes, use a lens to collect images of the target object, and the collected images can only reflect the shape of the two-dimensional surface of the monitoring target. Because plankton in seawater are three-dimensional living organisms, there are large differences in their shapes at different observation angles, and their shapes and postures during swimming are very random, resulting in different body images on the front, side and back. Different, but in the process of automatic processing and recognition ...

AI Technical Summary

Problems solved by technology

Traditional digital microscope imaging devices can only provide images of plankton in a single direction, and due to the randomness of plankton in the water space, it takes a long time to obtain images of the same plankton from different angles. Coastal plankton There are as many as hundreds of types, and it will take a lot of personnel, time and money to obtain images from various angles of these types

Therefore, the traditional single-sided microscope imaging technology is difficult to meet the intelligent and automatic development requirements of plankton category recognition based on computer vision technology
