Example Embodiment

[0032] The present invention will be described in further detail below with reference to the drawings and specific implementation examples.

[0033] As shown in Figure 1, Figure 2 and Figure 3, the present invention is mainly composed of a lighting system 1, a fruit moving unit 2, a detection system 3 and an analysis processing unit 4; among them:

[0034] 1) Illumination system 1 is shown in Figure 1, including illumination box 104, halogen lamp 103, hemispherical reflector 102, adjusting screw 101, nut 105, hinge 106, movable plate 107; halogen lamp 103 is installed on the hemispherical reflector In the center of the plate 102, the hemispherical reflecting plate 102 is fixedly connected with the adjusting screw 101. The adjusting screw 101 is fixed on the light box 104 by a nut 105. The height of the halogen lamp 103 can be adjusted by the adjusting screw 101; the halogen lamp 103 is the light source power It is adjustable, and different light source intensities can be used for ...

Abstract

This invention discloses one method and device to test fruit deficiency based on multi-sensor information integration, which comprises the following steps: using multiple testers to get light source to light fruit different parts spectrum information; test mode adopts continuous remove method and K near method or their combination and referring to fruit environment temperature and humidity factors to identify deficiency. This invention method uses multiple testers to test fruit to avoid leakage.

Description

technical field [0001] The invention relates to a method and device for fruit defect detection based on multi-sensor information fusion. Background technique [0002] Fruit defect detection is a very important step in the post-harvest processing of agricultural products. Separating defective fruits from normal fruits can prolong the storage period of fruits, increase the economic value of fruits, and maintain and improve the reputation of merchants. [0003] Fruit defects can be divided into two types: external defects and internal defects. Conventional methods for external defect detection use manual visual inspection or machine vision. However, manual visual inspection and machine vision can only detect external defects, but not internal defects such as water cores, etc. Internal defect detection often uses destructive methods for random inspection. Once the fruit is destroyed, it loses commercial value, and this method does not guarantee The unsampled fruits are free fr...
