Method and device of monitoring height of corn plants in wild environment

Abstract

The invention discloses a method and device of monitoring the height of corn plants in a wild environment based on an embedded type technology and a GPRS (General Packet Radio Service) wireless transmission technology, and belongs to the field of embedded type image processing and wild crop growth remote wireless monitoring. The invention comprises a device part and a method part. A data collection module of the device part utilizes a binocular stereoscopic vision principle; a data processing and transmitting module mainly utilizes the embedded type technology and the GPRS wireless transmission technology; and an independent power supply module mainly utilizes a photovoltaic power generation system to independently supply power to the whole device and the difficulty that no power grid exists in the wild environment is overcome. An embedded type image processing module of the method part can be used for eliminating the influences of wind power factors in the wild environment on corn plant images to the greatest extent; and a mobile terminal can be used for sending a wireless instruction through a GPRS wireless communication system, effectively and remotely controlling a whole data collecting and processing device to obtain a needed corn plant growth condition and performing the corresponding judgment and decision in time.

Description

technical field [0001] The invention relates to a method and device for monitoring the plant height of corn in the field environment. Background technique [0002] Corn is one of the important strategic materials related to the national economy, the people's livelihood and national economic security, and occupies a pivotal position in my country's agricultural production. Plant height is the most direct reflection of corn plant growth, and there is a large degree of correlation between the uniformity of corn plant height, reasonable dense planting in the field, and the number of corn ears. In order to achieve efficient, convenient and stable monitoring of corn plant height, research on related methods and devices has extensive and important significance for reasonably analyzing the growth of corn plants and improving corn yield. [0003] At present, the measurement of corn plant height is mainly realized by on-site manual observation and manual measurement. However, in the ...

Problems solved by technology

First of all, the overall cost of the controllable environment is too high, which requires a high facility cost; secondly, the design of the whole system for monitoring the growth of corn crops in the wild environment is complicated, and the monitoring on mobile terminal equipment cannot be realized; thirdly, video image acquisition The processing module's processing of the acquired corn plant images has not achieved the due efficiency and convenience. Its image processing algorithm is single, and the application environment is relatively harsh, especially it cannot adapt to the light, wind, rain and snow in the field environment. Due to the particularity of the field environment, the effective transmission of electric energy cannot be realized in many areas with harsh terrain and environment. Therefore, there is no practical way to realize the independent power supply of field monitoring equipment or devices. Program
