Description

A leaf image acquisition device

technical field

The invention belongs to the field of agricultural machinery and relates to a blade image acquisition device.

Background technique

The blade is the main part of the leaf, mostly flat, oval, oval, needle-shaped, needle-shaped, etc. According to the leaf shape, size, and surface color, the traits of the plant can be described or the growth and disease of the plant can be analyzed. It is often necessary to collect leaf characteristics during the growth of the plant.

At present, the acquisition of leaf phenotype data is mostly in vitro measurement of leaves, which affects the normal growth of plants. The existing leaf fixing device is not universal for leaves of different leaf shapes and sizes, which brings inconvenience to measurement, and the clamping parts are easy to cause leaf damage. And deformation, or cover leaves, affect the shooting effect and subsequent image processing and phenotypic data detection.

Contents of the invention

The purpose of the present invention is to provide a leaf image acquisition device, which is easy to operate, stable in work, capable of measuring phenotypic data of living leaves, and the external environment has little influence on the collected images, and is not easy to damage leaves.

The technical solution for realizing the above-mentioned invention is: a blade image acquisition device, including a camera obscura and a camera installed on the camera obscura, lighting lamps, and a background board. On the bottom surface of the interior, blade inlets are installed on the side walls of the dark box, and the blade inlets are adjacent to the background plate. Ventilation openings are respectively equipped on the bottom surface of the dark box and the side wall opposite to the blade inlets. Vertical fan, horizontal fan, the background board is made of breathable material, and the vent is a light-proof structure. The blade entrance is made of opaque, soft elastic material, and the blade entrance is a "rice" incision structure.

When the vertical fan is turned on, the blades can enter the dark box through the "meter" incision, and the horizontal fan can suck the blades to the breathable background board and lay them flat, and the camera collects images of the flat blades. The blade is in a flat state through wind suction, there is no shelter above the blade, and no contact extrusion damage will be caused to the blade.

The beneficial effects of the invention are: the device is simple in structure, small and portable, and easy to operate, and can realize the image collection of living leaves in the field; the negative pressure of the fan makes the leaves flat on the top of the air-permeable background board, and there is no shelter on the leaves, which can be collected The complete image of the leaf; the lighting is the source of light in the dark box to avoid the influence of the external environment on the collected image.

Detailed ways

The invention will be further described below in conjunction with the accompanying drawings and embodiments. A blade image acquisition device, comprising a dark box 1 and a camera 2 configured and installed on the dark box, a lighting lamp 3, and a background plate 4, each side wall of the dark box 1 is made of an air-tight material, and the background plate 4 is horizontally fitted inside the dark box 1 On the bottom surface 5 of the dark box 1, a blade inlet 6 is equipped on the side wall of the dark box 1, the blade inlet 6 is adjacent to the background plate 4, and a vent 7 is equipped on the side wall of the dark box 1 opposite to the blade inlet 6, and on the side wall of the dark box 1 The lower side of the bottom surface 5 is equipped with a lower vent 8, and a vertical fan 9 and a horizontal fan 10 are respectively fixed at the vent 7 and the lower vent 8, and the background plate 4 is made of a breathable material.

When collecting leaf images, place the device next to the plant, and the "meter" incision of the blade inlet 6 is facing the plant blade, and simultaneously turn on the vertical fan 9 and the horizontal fan 10, and the "meter" incision of the blade inlet 6 is sucked by the fan. Open, the blades are sucked into the dark box 1 through the incision, the vertical fan 9 is closed, the incision of the blade inlet 6 is closed, the horizontal fan 10 is turned on, the wind force is opened to the maximum, the blades are sucked to spread out on the breathable background plate 4, and the fan is turned on The lighting lamp 3 is switched on and off, and the camera 2 collects the leaf image to realize the image collection of a living leaf.

The invention is small and portable, easy to operate, and can realize the image collection of living leaves without affecting the normal growth of plants. There is no shelter above the leaves to facilitate the later processing of the leaf images. Effect, the camera obscura can adjust the light, the light will be weakened when it is sunny, and the light will be stronger when it is cloudy, which is convenient for image post-processing.
