Abstract

The invention relates to a corn seedling plant height measuring mechanism which comprises a transparent box body, a transparent box cover and a water absorption plate. The transparent box cover is arranged at the upper end of the transparent box body; the water absorption plate is horizontally arranged in the middle of the inner side of the transparent box body and is connected with the inner wall of the transparent box body; a plurality of planting holes are formed in the water absorption plate; a first moving device is arranged at the upper end of the transparent box cover, a second moving device is arranged at the lower end of the transparent box cover, and the first moving device and the second moving device are magnetically attracted; the first moving device drives the second moving device to move in the moving process; an ultrasonic range finder is arranged at the lower end part of the second moving device; a processor and a display are arranged on the side wall of the transparent box cover, and the processor is wirelessly connected with the ultrasonic range finder; the processor is connected with the display through a line. Compared with the prior art, the plant height of the corn seedlings is automatically measured, the measuring method is simple, the accuracy of measuring the plant height is high, and the convenience is improved.

Description

technical field [0001] The invention relates to the technical field of planting and germination, in particular to a mechanism for measuring the plant height of corn seedlings. Background technique [0002] In the prior art, the application number is 201710229283.0, a fully automatic method and device for measuring plant height of crops. First, the camera coordinate system, the ground coordinate system and the calibration plate plane coordinate system are established; after the system model is established, the device parameters are pre-calibrated, and the device The parameters include camera internal parameters, camera installation parameters and line laser plane parameters; the camera collects images and transmits the collected images to the control processor, which controls the line laser to turn on and off, and processes the images; according to the image processing The results and device parameters are used to control the processor to calculate and output the plant height...
