Citrus, orange, apple and other spherical fruits can greatly increase their sales prices through washing, sorting, waxing, preservation, drying, labeling, and packaging. In the harvest season, this series of processes is difficult to complete in a short time by labor. Therefore, a lot of research has been done in this area at home and abroad, and relatively good results have been achieved.
In the mid-1980s, China began to conduct a study on the grading method of spherical roller belt gaps. In 1987, the first prototype was manufactured. The current market share is large. With the development of computer technology, at the beginning of the 90's, domestic and foreign countries have made breakthroughs in the detection of size and appearance classification. At present, there are more mature computer size and color sorting equipment abroad. The computer detection of fruit surface defects has not been able to achieve a breakthrough. The main reason is that the current fruit conveyors have poor stability, which prevents the computer from quickly and accurately capturing images, and the computer computing speed and graphics processing software used cannot meet actual needs. .
Relevant experts say that there are five items that need to be researched as follows: First, improve and perfect the existing spherical fruit washing, waxing, sorting and preservation equipment as soon as possible to solve the problems of rough appearance, low processing accuracy and poor reliability of domestically produced equipment. . Second, carry out research on the theory and practice of computer vision real-time sorting technology for external quality of fruits. Third, design a computer real-time detection and processing equipment as soon as possible. Fourth, carry out trademark printing, labeling equipment development. Fifth, carry out research on the physiological and biochemical effects of collision on fruits. Designing a fruit positioning and holding mechanism for packaging.
