Portable long-distance plant size measuring instrument and measuring method thereof

Abstract

The present invention provides a portable long-distance plant size measuring instrument and the measuring method thereof which are used for acquiring phenotypic data of soybean plants in a field at any time and can also be used for acquiring phenotypic data of other outdoor plant images. The measuring instrument provided by the invention is a portable long-distance plant size measuring instrument,and comprises a measuring device and a mobile terminal. The mobile terminal is fixedly connected to the measuring device, and can be used for shooting plants. The mobile terminal receives measuring data sent by the measuring device, wherein the measuring data comprises parameters including the height from the mobile terminal to the ground during photographing of the mobile terminal, the distancebetween the mobile terminal and the highest point of the plants, an inclination angle during photographing of the mobile terminal and the like, various data and corresponding plant photos are bound, and the bound data is transmitted in a cloud server, the pictures are processed according to the data by adopting an artificial intelligence algorithm to obtain plant phenotypic data, namely the actualheight of a plant, and finally, the plant phenotypic data is stored into a plant phenotypic database.

Description

technical field [0001] The invention relates to the technical field of long-distance measurement, in particular to a portable long-distance plant size measuring instrument and a measuring method thereof. Background technique [0002] Soybean is an important grain and oil crop in the world, and it is also the main source of protein in human food. In order to breed high-quality soybean varieties, it is necessary to measure the phenotypic data of soybean crops, such as parameters such as height. However, the soybeans in the field are densely planted, and it is difficult for people to enter the field for height measurement. In production and life, people often encounter the problem that the measured object is too high or the distance is too far away. Although mobile terminals can be used to take pictures, it is still impossible to know the height of the target plant. At present, the commonly used method is to use a telescopic ruler to take a reading after close-distance measur...

However, soybeans are densely planted in the field, and it is difficult for people to enter the field for height measurement

In production and life, people often encounter the problem that the measured object is too high or the distance is too far away. Although the mobile terminal can be used to take pictures, it is still impossible to know the height of the target plant

At present, the commonly used method is to use a telescopic ruler to take a reading after close-distance measurement. The advantage of this method is that it is very accurate, but its limitations are very large: first, the efficiency is low and the workload is large. The cost of accurate measurement of taller plants is very high; second, if the taller plants are measured, they cannot be measured directly with a ruler, and the measured objects are limited to the situation where people can approach the target object and can touch the top, resulting in extremely difficult operation. inconvenient
