Embodiment Construction

[0035] The method and device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] A method and device for detecting enlarged kiwi fruit based on a mobile phone includes: a smart phone 1 , a kiwi fruit to be tested 2 , a background plate 3 , and an object stage 4 .

[0037] The working process of the described method and device of a kind of mobile phone-based kiwifruit enlarged fruit detection is as follows:

[0038] A method for detecting kiwifruit enlarged fruit based on mobile phone, comprising the following steps:

[0039] 1) if figure 1 As shown, the kiwifruit 2 to be tested is placed on the stage 4 of the background plate 3 with the side containing the pedicle facing up. Here, the influence of different background board 3 colors (such as black, blue, white, red, purple) on the segmented kiwi fruit area is analyzed. The results show that when the color of the background board 3...

Abstract

The invention discloses a kiwifruit expanded fruit detecting method and device based on a mobile phone, related to the technical field of non-destructive testing of fruit expanded fruit. The technicalproblem to be solved is to provide a kiwifruit expanded fruit detecting method and device which is low in cost and simple in operation. The method and system for realizing the detection of the kiwifruit expanded fruit are constructed by using the digital image processing technology. Obtaining an image of a kiwifruit pedicle side under a natural light through a smart phone; segmenting a pedicle part from the obtained image using a specific image processing method; and calculating an aspect ratio of the smallest circumscribed rectangle, and giving a judgment result whether the kiwifruit is an expanded fruit or not according to the aspect ratio of the smallest circumscribed rectangle. The invention can realize the non-destructive detection of the kiwifruit expanded fruit quickly, conveniently and at low cost, and provides a decision basis for the consumer.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of swollen fruit, in particular to a method and device for detecting swollen kiwi fruit based on a mobile phone. Background technique [0002] Kiwi fruit is rich in nutrients such as vitamin C, grape acid, and fructose. It is loved by consumers because of its rich nutrition and sweet and sour taste. Bulking agent, as a plant growth regulator that can increase the yield of agricultural products, has been widely used in the production of kiwifruit since the early 1990s. Although the application of bulking agent in the kiwifruit industry has increased the yield of kiwifruit, there are also some disadvantages: the storage time of kiwifruit dipped in the bulking agent is shortened; the inherent appearance of kiwifruit is destroyed, and the number of deformed fruits increases. It reduces the commerciality of the fruit; it is currently unknown whether eating kiwi fruit dipped in bulkin...
