Abstract: With the rapid development of information technology, orchard management has gradually become digitalized, mechanized and intelligentized. Accurate apple detection and localization in orchard environment will be the key of automatic fruit operation. This paper summarized the apple vision data acquisition methods, image preprocessing methods and apple image segmentation methods in orchard environment. The paper also analyzed the crucial approaches for apple occlusion and overlapping issues, concluded the main methods and principle for target apple localization, discussed the existing challenges in studies on apple detection and localization, and prospected the future development trend, so as to provide references for further  orchard informatization.

Key words: apple detection, localization methods, machine vision, orchard environment
