Embodiment 1

[0039] Such as figure 1 As shown, the embodiment of the present invention provides an automatic monitoring system for fruit appearance quality. The automatic monitoring system includes: an automatic fruit monitoring device, a communication device, and a server-side computing device.

[0040] The automatic fruit monitoring device includes a reference object 1, a background plate 2, a camera device 3, a calculation control device 4, a support 6, and a base 7.

[0041] The reference object 1 is a spherical object of known size and color, and its appearance shape is close to that of a fruit. The spherical reference object is fixed on the fruiting branch with a hard wire, and is on the same vertical plane as the fruit.

[0042] The background plate 2 is a flat plate of known color, which is beneficial to the segmentation of the target fruit during image calculation, and can also be used as a reference for the degree of fruit color change. The background plate can be fixed on the b...

Abstract

The invention provides an automatic monitoring system and method for fruit appearance quality. The system comprises an automatic fruit monitoring device, a communication device and a server terminal calculating device. Fruit image information is obtained through the automatic fruit monitoring device, an image is transmitted to a server through a transmission device, fruit size and color dynamic change information is obtained through image calculation, and important reference information is provided for production management of fruit trees. According to the automatic monitoring system, the fruit size is calculated through a method with the combination of an external connection maximum rectangular and a reference substance, the actual fruit color is calculated through color deviation comparison between fruit colors and a background plate or the reference substance. According to the automatic monitoring system and method, remote real-time monitoring of field fruits can be achieved, working efficiency is remarkably improved, meanwhile, the important reference decision is provided for production management of the fruit trees, and production of high-quality fruits is facilitated.

Description

technical field [0001] The invention relates to the technical field of crop information, in particular to an automatic monitoring system and monitoring method for fruit appearance quality. Background technique [0002] The dynamics of fruit growth and development affect the final quality of the fruit and determine the commodity price of the fruit. The measurement of fruit growth and development dynamics should not only pay attention to the change of fruit size, but also need to pay attention to the change of fruit color. At present, the size of the fruit is mainly measured manually in the field with a vernier caliper, and the color information is mainly measured with a colorimeter or a color card. This measurement method is discontinuous and easily affected by the weather, resulting in inability to measure on time. In addition, manual measurement is labor-intensive and time-consuming, making it difficult to grasp the whole process of fruit growth in real time. With the wid...
