Automatic observation method and device for crop development and growth

Abstract

The invention discloses an automatic observation device for crop development and growth. The device comprises an image acquisition part, a communication transmission system and a data processing centre, wherein the image acquisition part comprises a CCD camera, a video monitor and a lightning conductor which are fixed with a bracket; the bracket is arranged in a crop planting area; an antenna fixed to the top end of the bracket is in wireless connection with a computer which receives and processes the data of the crop development and growth and is arranged in a data processing centre through a wireless network; the communication transmission system comprises antennae and encoders respectively positioned on the image acquisition part and the two ends of the data processing centre; and the computer in the data processing centre comprises an image database, an image feature algorithm library and a product library. The device performs real-time automatic acquisition and identification on crop growth information, performs long-term observation, analysis and measurement remotely through a network, automatically measures aiming at the crop growth, has a simple measurement principle and an accurate measurement result, is convenient to popularize and use, and has significance to promote the modernization and the automation of agricultural meteorological observation.

Description

technical field [0001] The invention relates to a method and a device for automatically observing crop growth. Background technique [0002] At present, the observation of crop development and growth is mainly realized by manual observation. If people want to correctly identify the agrometeorological conditions required for the growth and development of crops, they must observe the development period. Through observation, the date and growth rate of each development period can be known. And understanding the external environmental factors that affect the growth rate will help people take reasonable agricultural technical measures according to the date of the arrival of the growth period to ensure high-yield and high-quality crops. [0003] However, in the practice of agricultural production, to manually observe the general situation of crop development period, one must select an important development period, which is closely related to the external environmental meteorologi...

Problems solved by technology

However, when plants are about to enter a certain developmental period or two developmental periods are very close to each other, as well as from the initial developmental period to the common period, observations should be made once a day. Such cumbersome manual observations are time-consuming and laborious, and it is difficult to conduct real-time observations of crops, often resulting in observations. large error, and the timeliness of the data is poor, and it is also very cumbersome to count all the observation data

[0004]Now there is also a computer vision technology and color image processing technology to monitor crop growth instead of manual observation. Although observation can be realized, it cannot be fully automated. The cost of the entire observation system Higher, it is impossible to systematically form a crop product library for the measurement of external growth parameters of crops, the detection of fruit maturity, the monitoring of crop nutritional status, and the description and identification of crop shapes
