Description
technical field [0001] The invention relates to a plant cultivation dimming control system, in particular to an adaptive plant cultivation dimming control system based on machine vision. The adaptive plant cultivation dimming control system adopts the combination of machine vision and adaptive neural network control strategy The method measures the growth height of the plant, and adaptively controls the illumination and light quality ratio of the LED lamp according to the growth height of the plant, making it more conducive to the growth of the plant. Background technique [0002] The light intensity and light quality ratio of LED lights have a great influence on the growth of plants. On the one hand, different light intensities affect the photosynthesis of plants. Too high or too low light intensity will have a negative impact on the growth of plants. This requires providing a suitable light intensity. On the other hand, plants have different absorption abilities to differ...
