The utility model discloses a cultivation box convenient to classify and compare, and particularly relates to the technical field of crop cultivation, which comprises a planting box, a partition frame fixedly connected in the planting box, a water pump mounted at the top end of the planting box, fan boxes fixedly connected to two sides of the planting box, and communicating pipes communicated with the output end and the input end of the water pump. Wherein one end of one communicating pipe is communicated with a flow dividing pipe, the bottom end of the flow dividing pipe is communicated with a conveying pipe, the conveying pipe is fixedly connected with the interior of the planting box, a drip irrigation assembly and an adjusting mechanism are installed in the planting box, and the adjusting mechanism is installed above the drip irrigation assembly. By arranging the drip irrigation assembly and the adjusting mechanism, the distance between the drip irrigation heads can be adjusted according to the root depth and density of different corn varieties, so that the plant lamp can adapt to the change of the corn growth stage, and meanwhile, the height of the plant lamp can be adjusted according to the growth requirements of corn seedlings to meet the requirements of different stages.

The invention discloses a TDI camera-based product detection method and system, and a medium. The method comprises the following steps: installing a line light source; the light intensity of the line light source is controlled to be in periodical light and shade stroboflash according to stripe distribution, so that stripe images meeting the phase shift method under the RGB three channels are obtained; analyzing stripe images under three channels of RGB, and calculating and obtaining original height data of all pixel positions under each channel of RGB based on phase deflection; traversing the original height data of all pixel positions so as to obtain final height data of the current pixel position through weighted averaging according to RGB channel weights corresponding to the current pixel position; according to the method, the TDI true color camera is used for collecting the three-channel fringe images, channel crosstalk and response inconsistent errors are restrained through a self-adaptive weighted average mechanism, high-speed measurement is guaranteed, meanwhile, the reconstruction precision and robustness of phase deflection are remarkably improved, and false data introduced by interpolation are avoided.

The application discloses a plant LED lighting system, comprising: a plurality of groups of light sources, each group of the light sources comprising a plurality of LED light source components; and a constant current power supply, the length of the power supply line of the constant current power supply to each of the LED light source components in the same group of the light sources being consistent; the length of the power supply line of the constant current power supply to each of the LED light source components in the same group of the light sources being consistent, that is, the distance of the constant current power supply output to each of the LED light source components in the same group of the light sources being consistent, balancing the line loss of each output power supply line, achieving the balance of the output current of each of the LED light source components in the same group of the light sources, realizing the consistency of the light intensity of a single group of the light sources, and the consistency of the uniformity of the light illumination in the area.
