Gantry type hyperspectral image collecting system for gardening plantlet crops

Abstract

The invention belongs to the technical field of modern agriculture and discloses a gantry type hyperspectral image collecting system for gardening plantlet crops. A servo motor is fixed to the upper portion of a support through bolts, the servo motor is connected with a movable platform through a synchronous belt, two ends of the movable platform are in slide connection with slide rails, and the slide rails are arranged on two sides of the upper portion of the support; a hyperspectral camera, a micro computer, a battery and an initiative light source lamp are fixed to the movable platform through bolts; the hyperspectral camera is connected with the micro computer through an optical fiber, the micro computer is connected with a notebook computer and the like through WiFi (Wireless Fidelity), and the notebook computer can control the hyperspectral camera to collect images and the servo motor to drive the movable platform to move. The gantry type hyperspectral image collecting system disclosed by the invention can collect hyperspectral images of varieties of gardening plantlet crops and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of modern agriculture, and in particular relates to a gantry type hyperspectral image acquisition system for horticultural small plant crops. Background technique [0002] Hyperspectral image: A spectral image with a spectral resolution less than 10nm is called a hyperspectral image. A hyperspectral image is a data cube obtained through hyperspectral equipment, which is a combination of image and spectrum. On the spatial feature image of the target, each pixel has a piece of spectral information. Image information can reflect the size, shape, texture and other characteristics of the sample, while spectral information can fully reflect the differences in the physical structure and chemical composition of the sample. [0003] The push-broom imaging principle of hyperspectral images requires stable relative motion between the sample and the hyperspectral device. In order to obtain a stable hyperspectral image...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problem existing in the prior art is: but for the hyperspectral image acquisition of small horticultural crops such as vegetables and fruits cultivated in nurseries, greenhouses or outdoors, there is a vertical orthographic collision between the hyperspectral imaging equipment and the sample. It is difficult to maintain a relatively constant speed and uniform motion, and it is difficult to collect stable and qualified hyperspectral images
