Method and device for quickly judging dry matters of fruits on trees

Abstract

The invention discloses a method and a device for quickly judging dry matters of fruits on trees. The method comprises the following steps: A, respectively carrying out hyperspectral image data acquisition and dry matter content measurement on fruit samples on the tree on a plurality of fruit samples on the trees; B, enabling a data processing module to carry out quality prediction model training based on the hyperspectral image data and the dry matter content of the fruit samples on the plurality of trees; and C, performing hyperspectral image data acquisition on the target fruit on the tree, and predicting the dry matter content of the target fruit on the trees by using the quality prediction model. The method and the device for quickly judging the dry matter of the fruits on the trees can directly measure the content of the dry matter of the fruit on the tree on site, and have the advantages that the fruit can be simultaneously, massively, quickly and nondestructively detected, and continuous operation can be realized.

Description

technical field [0001] The invention relates to modern automatic agricultural technology, in particular to a method for measuring fruit characteristics in agricultural planting. Background technique [0002] Fruit dry matter refers to the remaining organic matter after the organism is fully dried at a constant temperature of 60°C-90°C. Dry matter is directly related to the starch and sugar content in the fruit. For some fruits, such as kiwi, mango, banana, avocado, apple, cherry, etc., the dry matter content is considered an important indicator for judging the ripeness of the fruit. For the determination of fruit dry matter content, the methods currently used can be divided into destructive and non-destructive methods. [0003] The damage method is usually to dehydrate the fruit sample on the tree, measure the mass of the remaining substance, and calculate the ratio of it to the mass before dehydration to obtain the dry matter content of the fruit sample on the tree. In a...

Problems solved by technology

[0007] In order to solve the damage method in the prior art to determine the dry matter content of the fruit will cause damage to the fruit samples on the tree, produce a large amount of waste, and need to consume a certain amount of manpower and material resources, and need to go through a dehydration process, which takes a long time and cannot be used for the tree. The technical problem of rapid determination of fruit dry matter content; and although near-infrared spectrometers and hyperspectral instruments can achieve non-destructive determination of fruit dry matter content, due to their large size, they can only be used for dry matter content determination in laboratory scenarios. The technical problem that the rapid determination of the dry matter content of the fruit on the tree cannot be realized, the present invention proposes a method and device for quickly determining the dry matter content of the fruit on the tree, which can directly measure the dry matter content of the fruit on the tree in the field, and has the ability to realize simultaneous , a large number of fast, non-destructive testing of fruit, and the advantages of continuous operation
