Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 , a display diagram of the realization of the present invention. The whole device is divided into hardware and software. The hardware part includes: CCD camera 1, integrated device for collecting visual and olfactory information 2, detected fruit samples 3, visual gas sensor array 4, computer 5, and scanner 6. The software part is composed of the driver program of the scanner 6, the image processing program of the computer 5 and the pattern recognition module.

[0026] The present invention has versatility for detecting the freshness of fruits during the storage period. Since there are many types of fruits, the integrated device for collecting visual information and olfactory information in the present invention lists specific structures and sizes for bananas and tomatoes. The specific implementation steps are describ...

Abstract

The invention discloses an intelligent judgment method for fruit freshness based on coordination of visual information and olfactory information, and belongs to the technical field of non-destructive testing of foods and agricultural products. The intelligent judgment method comprises the following steps: using a computer vision system to monitor the change of surface characteristics of a fruit; using an olfactory information imaging system to monitor the change of smell of the fruit; establishing a relationship between fruit appearance information, such as surface color and texture, and each of fruit smell characteristic information and fresh freshness at the same time; simulating a human identification method; and performing intelligent judgment on the freshness of fruits at a storage stage based on visual information, olfactory information, in particular coordination of the visual information and the olfactory information. The intelligent judgment method adopts the judgment process not destructive to a detection object, has higher detection accuracy and reliability relative to the single visual or olfactory detection method, can perform intelligent management on the fruits according to the freshness in the storage process, can effectively reduce the post-harvest loss of the fruits, and achieves agricultural income increase.

Description

technical field [0001] The invention relates to an intelligent judging method of fruit freshness based on synergy of visual and olfactory information, mainly for judging the freshness of fruits during storage, and belongs to the technical field of non-destructive testing of food and agricultural products. Background technique [0002] With the development of the modern fruit industry, the production of a large number of fruits is concentrated in areas with favorable climate, soil and proper irrigation. In order to ensure the supply of high-quality fresh fruits in the domestic and international markets, major fruit-producing areas are currently using modern storage methods and transportation equipment to supply the national market and export all year round. In the process of storage and transportation, due to some unfavorable factors such as collisions and bumps between fruits during transportation, environmental changes and the respiration of fruits themselves, the freshness...
