Abstract

The invention discloses an online nondestructive testing (NDT) method and an online nondestructive testing (NDT) device for comprehensive internal/external qualities of fruits. The online NDT method of the invention comprises the following steps: a comprehensive quality evaluation model for the fruits is established firstly by a detection device consisting of a conveying system, a machine vision system, an Near Infrared Spectrum (NIR) system and a grading system, and the fruits performs online uniform motion through the conveying system; the machine vision system acquires the image information of the fruits and extracts the external characteristics of the fruits; the NIR system acquires the spectral information of the fruits; the grading system analyses the spectral information by a pre-established mathematical model, and extracts the internal characteristics of the fruits; and the grading system fuses the internal characteristics and the external characteristics of the fruits by a pre-established information fusion model so as to obtain the comprehensive quality level of the fruits. The method and the device of the invention can detect the internal characteristics and the external characteristics of the fruits simultaneously; a DSP high-speed image processing system is used to handle complex image information, which greatly improves the real-time characteristic of the system; and an information fusion technology is used to carry out online real-time detection on the comprehensive qualities of the fruits.

Description

technical field [0001] The invention relates to an online non-destructive detection method for internal and external comprehensive quality of fruits, in particular to a method and device for rapidly non-destructive detection of internal and external comprehensive quality of fruits by using DSP machine vision and near-infrared spectroscopy. Background technique [0002] Fruit is the third largest planted product after grain and vegetables in China. Since the middle and late 1980s, my country's fruit has developed rapidly. In recent years, my country's fruit production ranks first in the world. According to the plan of the Ministry of Agriculture, the fruit output in 2010 will reach 93 million tons. With the continuous increase of fruit production and the continuous improvement of people's living standards, consumers not only pay attention to the choice of fruit appearance quality, but also pay more attention to the internal quality of fruits, such as taste, sugar content, ac...
