Description

Technical Field

[0001] This utility model relates to the field of visual recognition device technology, specifically to an adjustable height visual recognition device for blueberry fruit identification. Background Technology

[0002] In the process of developing modern intelligent agriculture, the accurate identification of blueberries, as a high-value berry fruit, is a core link in achieving automated harvesting and efficient sorting. Traditional blueberry fruit identification relies heavily on manual labor, which is not only inefficient and costly, but also susceptible to human factors, making it difficult to guarantee accuracy and failing to meet the needs of large-scale blueberry industry development.

[0003] Existing machine vision-based blueberry fruit recognition technologies mostly employ fixed-height vision recognition devices. However, blueberry plants grow irregularly, with significant differences in plant height and fruit distribution. Fixed-height vision recognition devices struggle to adapt to the complex and ever-changing field environment, easily leading to blind spots or poor shooting angles, resulting in reduced fruit recognition accuracy and consequently affecting the efficiency and quality of subsequent harvesting and sorting operations.
