Abstract

The inventions relates to a light-emitting diode (LED) lamp box used for collecting high-quality images of agricultural materials. The LED lamp box comprise a box body, a red-green-blue (RGB) three-channel LED light source, a power line of the LED light source, an LED light source controller, an object stage, an adjusting support of the object stage, a lamp box door and the like. The LED lamp box is characterized in that the LED light source is fixed at the top of the lamp box through M3 cross-shaped sunk screws, the power line of the light source is led out of the top of the lamp box and connected with the LED light source controller, different illumination colors are configured through adjustment of the proportion of illumination intensity of three channels of red, green and blue, the object stage and the adjusting support of the object stage are fixed at the bottom of the lamp box, and the lifting and lowering of a lead screw is adjusted through a rotation handle to adjust the height of the object stage. When the LED lamp box is used, the high-quality images of the agricultural materials can be obtained through adjustment of the illumination intensity of the three channels of red, green and blue, the height of the object stage, a camera and camera parameters to further reduce the difficulty of an image analysis algorithm.

Description

technical field [0001] The invention relates to a light box, in particular to an LED light box with adjustable wavelength, light intensity and multi-parameter adjustable height of a stage for collecting high-quality images of agricultural materials. Background technique [0002] Appearance information such as shape, size, area, and color of agricultural materials are important indicators to measure their quality characteristics. At this stage, image analysis methods are usually used to obtain such information. In order to reduce the difficulty of algorithm development, improve the accuracy of information acquisition and reduce the calculation time, it is usually necessary to collect high-quality images with the best separation of target information and background information. Designing a reasonable lighting environment is an effective way to obtain high-quality images. Due to the advantages of low power consumption and long life of LED light sources, a variety of LED light ...
