Abstract
Description
Technical Field
[0001] The utility model relates to the field of agricultural information technology, and particularly relates to a set of equipment and method for push-broom type indoor high-throughput automatic acquisition of plant hyperspectral images. Background Art
[0002] Compared with traditional RGB imaging and multispectral imaging, hyperspectral imaging contains detailed spectral data of hundreds of bands, so it can better detect the subtle physiological states of crops reflected in the near-infrared band of plants. Among them, hyperspectral detection equipment using grating dispersion type hyperspectral sensors has the characteristics of high spectral resolution and can be used for non-destructive quality detection of agricultural products such as seeds, vegetables, fruits, and meats. Hyperspectral detection equipment can be roughly divided into crawler type and push-broom type. The crawler type hyperspectral detection equipment places the sample on the conveyor belt, with poor stability and small single-pass throughput; while the push-broom camera relies on its own horizontal movement for shooting, does not require fixing the sample, has a fast acquisition speed, and a stable system. Since the engineering design of the crawler type detection equipment is relatively simple, it is the mainstream hyperspectral detection equipment on the market, while the push-broom type detection equipment is almost non-existent on the market. Other hyperspectral detection equipment for plant organs on the market generally requires picking plant organs and placing them in specific positions, and cannot achieve non-destructive detection. Under this background, it is necessary to develop a set of push-broom type indoor high-throughput automatic acquisition equipment for plant hyperspectral images, which has the advantages of being miniature, having good equipment stability, high cost performance, large throughput, and convenient operation, and is suitable for quickly collecting hyperspectral images of plant samples indoors. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a device and method for indoor high-throughput automatic acquisition of plant hyperspectral image data with a simple structure and convenient operation. The shooting equipment such as a push-broom camera is fixed and moved uniformly along the track together, which can enable the equipment to be directly placed on the platform for in-vivo detection of plant potted samples. A large number of whole plants can be inspected at one time, and through the built-in automatic control system, the detection, recording, and resetting can be started with one key to obtain the hyperspectral data information of plant samples in real time.
[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0005] A set of equipment for push-broom type indoor high-throughput automatic acquisition of hyperspectral images of plant samples, including a bracket, a ball screw slide table module, a single-axis controller driver power control box, and a shooting device; the shooting device includes a push-broom camera; among them, the ball screw slide table module is fixedly installed downward on the bracket, the shooting device is arranged downward on the ball screw slide table module, and the single-axis controller driver power control box is connected to the ball screw slide table module to provide power for the ball screw slide table module and control the single-axis movement of the ball screw slide table module and the shooting device arranged on the ball screw slide table module; the push-broom camera can adjust the focal length to adapt to the height of the sample.
[0006] Furthermore, it also includes a computer device connected to the push-broom camera, and the computer device is used for collecting and real-time monitoring of shooting.
[0007] Furthermore, the shooting device also includes halogen lamp strips detachably arranged around the push-broom camera. The halogen lamps on the halogen lamp strips can be arbitrarily detached and replaced to adapt to different shooting requirements.
[0008] Furthermore, the halogen lamp strip is electrically connected to the single-axis controller driver power control box, and the single-axis controller driver power control box provides stable power for the halogen lamp strip.
[0009] Furthermore, the single-axis control driver uses a CPU chip, which is a Chinese programmable controller. An automatic program can be set, and the automatic operation mode can be set by the operation panel to achieve automatic operation, which can improve the control accuracy and the reliability of the controller, make the motor run smoothly and with low noise. Among them, the operation panel is simple and convenient, and beginners can also quickly get started with the operation.
[0010] Furthermore, transmission limit modules are also arranged on both sides of the ball screw slide table module.
[0011] Furthermore, the push-broom camera is a grating dispersion type hyperspectral camera, and each pixel point of the hyperspectral image collected by the push-broom camera contains data in the 400 - 1000 nm band. The push-broom camera has a high spectral resolution, and all wavelengths are imaged simultaneously, obtaining spectral data of all wavelengths at each point on a line at one time, which is very suitable for classification and quality detection of plant samples, etc.
[0012] The equipment for push-broom type indoor high-throughput automatic acquisition of hyperspectral images of plants provided by the present utility model places the equipment on the tabletop, places the plant samples on the shooting tabletop, and operates the control panel of the power box to conduct shooting experiments. Among them, the plant samples remain stationary, and the camera automatically runs back and forth on the slide rail for shooting, and can be monitored and recorded through the computer device. Through the periodic photographing of the shooting equipment, hyperspectral images of plant samples are obtained.
[0013] The beneficial effects of the present utility model are as follows:
[0014] (1) Traditional indoor hyperspectral detection equipment is relatively messy and is generally designed as different shooting platforms for seeds, leaves, or other plant organs. However, the present utility model can be moved arbitrarily and uses a variable-focus lens, which is suitable for shooting different plant organs such as seeds and leaves, and can also perform non-destructive detection on the whole live plant.
[0015] (2) Ordinary push-broom hyperspectral cameras require a stable mounting platform. Generally, the camera is fixed while the sample and the light source are moved together, resulting in a small single-shot throughput. In the present utility model, the hyperspectral camera and the light source move stably and uniformly together, and the sample can be placed at any position on the table within the effective stroke, with a high single-shot throughput.
[0016] (3) Generally, small hyperspectral detection equipment on the market is manually controlled. The present utility model is equipped with a Chinese programmable single-axis control driver with a CPU chip, which can achieve automated operation. Description of the Drawings
