[0002] Humidity is an important factor affecting seed germination and directly affects the physiological processes of plants. Existing phenotypic collection equipment is difficult to meet the high humidity requirements of seeds such as soybeans during germination, resulting in a low seed germination rate. Previous technologies for obtaining seed germination phenotypic data, such as using plant phenotypic imaging equipment and fill lights to collect images in an artificial climate culture room, are prone to seed contamination, low germination rates, and collected images that reflect light, which often affects the efficiency and results of the experiment. Moreover, existing plant phenotypic imaging equipment often uses digital cameras, which have the disadvantages of longer shutter times, slower shooting speeds, and narrow spectral ranges of output images compared to industrial cameras. They are not suitable for high-quality image processing algorithms and cannot be applied to machine vision systems. Therefore, it is urgent to study an automated seed germination phenotyping device that collects images without reflections and shadows, has high humidity during germination and is not easily contaminated, and has good equipment stability.
