Abstract

The invention provides a crop height measuring method and a plant protection machine gear adjusting method and device. The crop height measuring method is applied to a height measuring system, the height measuring system comprises a laser head used for emitting laser rays and a camera used for obtaining images, and the method comprises the steps that when the laser head is started, the camera is started; when the laser head is turned off, a first farmland image containing crops is obtained through the camera, and when the laser head is turned off, a second farmland image containing crops is obtained through the camera; a maximum offset pixel coordinate of a laser ray position relative to a horizon line is determined according to the first farmland image and the second farmland image; a crop height measurement model is determined according to the maximum offset pixel coordinate; and the height of the crop is measured through the crop height measurement model. The height of the crop is measured based on image detection, the manual intervention degree and the labor intensity are reduced, the height of the crop can be intelligently measured, and the efficiency and the reliability of crop height measurement are improved.

Description

technical field [0001] The invention relates to the technical field of crop height measurement, in particular to a crop height measurement method, a plant protection machine gear adjustment method and a device. Background technique [0002] With the rapid development of big data and communication technology, a new model of smart agriculture based on artificial intelligence has begun to emerge. Machine vision technology provides important technical support for field information acquisition and identification, and its application has penetrated into all aspects of modern agricultural automation production. field. During the growth period of crops, the growth state of plants will be uneven due to various reasons such as seeds, light, water level, and soil nutrients. When farmers use plant protection machines for operations, they need to adjust the amount of inputs such as pesticides and fertilizers according to the growth status of the crops. [0003] The traditional method o...
