Embodiment 1
[0036] Citrus with different sugar content has different absorption and reflection of electromagnetic waves in different bands during the growth process, which makes its appearance and coloring different, thus forming different colors on the appearance of the fruit. Therefore, the sugar content of citrus can be ascertained and graded non-destructively by means of color images.
[0037] Such as figure 1 As shown, the present embodiment provides a method for determining the sugar content of fruit, comprising the steps of:
[0038] Step 11, obtain the color image and weight of the fruit.
[0039] The color image is obtained by a camera, and the weight can be obtained by a weight sensor or an electronic scale.
[0040] Step 12, obtain sugar content parameter from the color image of fruit;
[0041] Step 13, determine the sugar content of the fruit by using the sugar content model according to the sugar content parameters and weight
[0042] In step 12, in order to obtain the su...
Embodiment 2
[0091] This embodiment provides a device for determining the sugar content of fruit, which includes:
[0092] The information acquisition device is used to obtain the color image and weight of the fruit; the image acquisition device can be a camera or any equipment with a camera, and the weight is obtained by a weight sensor or an electronic scale; the calculation unit is used to obtain the color image of the fruit A sugar content parameter is obtained; a determination unit is used for determining the sugar content of the fruit by using a sugar content model according to the sugar content parameter and weight.
[0093] For the working principle of each unit in this embodiment, refer to the description of Embodiment 1.
[0094] According to the present invention, the sugar content of fruit can be measured by ordinary cameras and computers. Therefore, the present invention does not need to add additional equipment to estimate the sugar content of fruit. The technology of the pre...

Abstract
Embodiments of the present invention provide a method and device for determining the sugar content of fruit, which can realize non-destructive estimation of the sugar content of fruit. The method comprises: obtaining the color image and weight of the fruit; obtaining the sugar content parameter from the color image of the fruit; and determining the sugar content of the fruit by using a sugar content model according to the sugar content parameter and the weight. The device includes: an information acquisition device, used to obtain the color image and weight of the fruit; a calculation unit, used to obtain the sugar content parameter from the color image of the fruit; a determination unit, used to determine the sugar content of the fruit by using a sugar content model according to the sugar content parameter and weight . According to the present invention, the sugar content of fruit can be measured by ordinary cameras and computers. Therefore, the present invention can estimate the sugar content of fruit without adding additional equipment, and is extremely suitable for fruit grading in small enterprises.
Description
technical field [0001] The invention relates to a technology for determining fruit quality, in particular to a method and device for determining the sugar content of fruit. Background technique [0002] The prices of fruits of different qualities vary greatly, and fruit quality grading has always been valued by fruit farmers and merchants. Different from the sampling inspection of the quality of many items, fruit grading requires that each fruit be graded. Since the quality of fruit is often manifested in the external form, it is possible for people to infer the internal information of the fruit through the external form. With the simplification and cheapness of digital image acquisition, the image-based fruit quality research is objectively promoted, and it is hoped to realize the automation of fruit quality detection. In this kind of research on fruit quality, because citrus has a wide distribution range and large yield, it has become a hot spot of concern. The following...
