Strip-shaped Fuji apple fruit identification method and system based on digital image processing

Abstract

The invention provides a strip-shaped Fuji apple fruit identification method and system based on digital image processing, and belongs to the technical field of computer vision, and the method comprises the steps: obtaining a calyx image of a to-be-identified fruit; matching the calyx image of the to-be-identified fruit with images in a pre-constructed fruit texture structure database one by one, and calculating the number of successfully matched point pairs; calculating the matching degree according to the number of successfully matched point pairs; and comparing the matching degree with a preset matching degree threshold value, and determining whether the to-be-identified fruit is the same as a fruit in the pre-constructed fruit texture structure database or not according to a comparison result. According to the method, identification is performed according to texture structure features of the calyx image, the extreme point is calculated in the scale space, and direction, scale and position coordinate information is given, so that accurate identification of fruit individuals is realized, and the identification accuracy is improved; the agricultural product selling cost is reduced, and the problems that information is tampered and lost and resources are wasted due to paper label identification are solved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for identifying strip-shaped red Fuji apple fruits based on digital image processing. Background technique [0002] The primary apple products after picking need to be commercialized before they become commodities. This process is of great significance to ensure the quality of the fruit, facilitate storage and transportation, and promote sales. The commercialization process of apples mainly includes harvesting, selection and grading, cleaning, waxing, packaging, pre-cooling, preservation, preservation, storage, transportation and other links. [0003] Apples need a series of technical treatments after harvesting and before storage. At present, the most applied technical treatments in the actual production process include cleaning and waxing treatment, pre-storage and callus treatment, and anti-corrosion and fresh-keeping treatment. After the treatment...

AI Technical Summary

Problems solved by technology

However, this technology cannot guarantee real-time tracking during the entire post-harvest commercialization process of apples. Some processes may cause the label to fall off, and then the information on the label will be tampered with, such as: cleaning and waxing, antiseptic preservation, etc.

In addition, the adhesives used to paste paper labels have a small amount of toxicity, and the production of paper labels also wastes certain natural resources (wood, water, energy)

In addition, the traditional method of sticking paper labels to realize the identification of individual apples will increase the cost of time, manpower, and material resources.
