Description

Technical Field

[0001] The present invention belongs to the technical field of image processing, and particularly relates to a method for processing images of large insect specimens. Background Art

[0002] Insects are the general name of animals in the class Insecta of the phylum Arthropoda. They are one of the animal groups with the widest distribution, the richest species, and the largest number on the earth, and are extremely important for human life, production. Insect specimens are necessary materials for studying insects, but it is difficult to preserve insect specimens and they are easily damaged. Therefore, high-quality digitization of insect specimens can not only effectively preserve and present insect specimens, but also facilitate more people to view insect specimens more conveniently. Real and clear image acquisition and presentation of insect specimens are the key steps. At present, the technologies for image acquisition and processing of insect specimens mainly use various optical photography devices to initially collect images, and then use various software to further process the images after importing them into a computer, and finally obtain clear and real pictures of insect specimens.

[0003] In the prior art, the 3D ultra-depth-of-field microscopy technology mainly includes an integrated computer system, a main controller, a high-brightness LED illumination, a lens, a data control line, a tiltable manual support, a two-dimensional transmission / reflection moving platform, and a special insect 360° annular anti-reflection illumination device. When high-definition pictures of large insect specimens are needed, usually, due to the specimen being too large to exceed the microscope field of view under high magnification, the overall picture of the large insect specimen cannot be obtained. Only by moving the stage, three-dimensional synthetic photography is carried out on different regions respectively to obtain local pictures of a certain morphological feature of the insect; then through the image stitching function, and finally a complete clear image of the large insect specimen is composed through synthesis.

[0004] The 3D ultra-depth-of-field microscopy technology is an integrated device for observing and photographing insect specimens, and the cost of a set of equipment is relatively high. Moreover, the integrity of this device is extremely high and it cannot fully adapt to insect specimens with various shapes and forms. For obtaining the overall high-definition image of a slightly larger insect specimen, the high-definition images synthesized in three dimensions for each region need to be synthesized again. And there is a possibility of missing a certain part when manually adjusting to obtain images of each part, resulting in the final synthesized overall image not being the true situation of the insect specimen. Summary of the Invention

[0005] Aiming at the above deficiencies in the prior art, the present invention provides a method for processing images of large insect specimens, which realizes high-definition image acquisition and processing of large insect specimens under the conditions of low cost, portability, and high adaptability, and promotes the digitalization process of insect specimens.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A method for processing images of large insect specimens, comprising the following steps: S1. Insert a single large insect specimen into a specimen box and vertically place the specimen box in a photography studio. S2. Assemble the shooting equipment and adjust the height of the tripod and the large insect specimen to be photographed so that they are on the same horizontal line. S3. Turn on the lights in the photography studio and adjust the brightness and color temperature to make the image of the large insect specimen in the camera realistic. S4. Adjust the distance between the large insect specimen and the camera and the camera focal length, and collect the specimen image. S5. When the collected specimen image meets the requirements, rotate the shooting equipment to move the camera away from the large insect specimen, and observe the macro scale and collect the specimen image. S6. Synthesize the collected specimen images to complete the processing of the large insect specimen image.

[0007] Further, S4 is specifically as follows: S401. Adjust the distance between the large insect specimen and the camera and the camera focal length. Among them, when the large insect specimen is farthest from the camera, the image is the clearest. S402. Press the remote shutter release to collect the first specimen image. S403. Check whether the quality of the first specimen image meets the requirements. If so, go to S5; otherwise, return to S401.

[0008] Still further, S5 is specifically as follows: S501. When the first collected specimen image meets the requirements, rotate the knob of the panoramic head to move the camera away from the large insect specimen. S502. During the movement, observe the macro scale. Among them, every time a preset distance threshold is moved, press the remote shutter release to collect a specimen image once. During the movement, observe the image of the large insect specimen in the camera. The image of the large insect specimen gradually becomes clear from the farthest point to the nearest point from the camera until the nearest point becomes blurred, then stop collecting the specimen image.

[0009] Still further, S6 is specifically as follows: Import all the collected specimen images into image processing software. Synthesize all the collected specimen images into a large insect specimen image with clear parts, and complete the processing of the large insect specimen image.

[0010] Advantages of the present invention: The present invention is applicable to the image acquisition of various insect specimens. Each component can be adjusted and replaced according to the specific conditions of photographing insect specimens and the environment to adapt to more insect specimens with large differences in body shape, shape, etc. For example, when photographing insect specimens with large differences in body shape, the corresponding lens can be replaced to ensure that the image acquisition process is simple and each part of the photographed insect specimen image is clear. The overall high-definition image is synthesized from the overall images of different focus points, and a completely clear overall photo is synthesized from multiple partially clear overall photos, which maximally ensures the authenticity of the image and the reduction of the insect specimen. The present invention realizes the acquisition and processing of high-definition images of large insect specimens under the conditions of low cost, portability, and high adaptability, and promotes the digitalization process of insect specimens.
