Apple is an important fruit crop, rich in minerals and vitamins, sweet and sour, suitable for all ages, and occupies a large proportion in the fruit market. Due to the influence of light, nutrients, and pests, the quality of the fruit in the same fruit forest or even on the same tree is uneven. Apples with round shapes, smooth surfaces, and uniform ruddy colors can be exported and sold at relatively high prices. However, apples with scars on the surface and low coloring rate can only be sold at relatively low prices, and some are even worthless and can only be thrown away. Therefore, it is very important to judge and grade apples.

China is the world's largest apple producer and consumer, with apple planting area and output accounting for more than 40% of the world's total, occupying an important position in the world's apple industry. For a long time, it is an unscientific method to classify apples only by weight and size. Weight cannot represent the quality and maturity of apples. Only by distinguishing the surface color of apples can we judge the quality of apples. If we rely on artificial naked eyes to judge and grade apples, a lot of manpower will be invested, and affected by personal subjective factors, the grading accuracy and consistency are poor, and the grading quality is not good. to guarantee.

Appearance shape, surface color, coloring rate, and defects are important characteristics of apple quality, which are difficult to analyze by traditional methods.
