Abstract:

With the development of economy and the improvement of consumption level, consumers have gradually increased the requirements for the appearance quality of fruits. At present, the classification of fruits in China mainly depends on manual and mechanical classification. There are problems of low sorting efficiency and uneven quality, which is difficult to meet consumer demand. Compared with traditional grading technology, machine vision technology has attracted widespread attention from scholars at home and abroad due to its advantages of high efficiency, accuracy, and non-contact measurement. Based on the research progress of scholars at home and abroad in recent years, this paper introduces fruit detection systems, image denoising, image segmentation techniques, and feature extraction in detail. It also comprehensively analyzes classifier recognition algorithms, and elaborates research on fruit classification based on machine vision current status and latest progress, forecasts possible future development trends, and provides basic theoretical references for subsequent research.
