Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a device for intelligent orientation recognition and automatic cutting of potato seed buds. Background Technology
[0002] To reduce potato planting costs, potatoes need to be cut into pieces, retaining the parts with eyes. Eyes are dormant buds located in depressions on the surface of potato tubers; preserving these eyes during cutting ensures that each seed potato has reproductive capacity. Therefore, cutting potato seed tubers with eyes is a key technology in pre-planting seed tuber segmentation, aiming to improve germination rate and yield by scientifically cutting to retain healthy eyes. Current technologies use machine vision and other techniques to identify potato eyes before cutting. While machine vision and similar technologies can accurately identify seed buds on potatoes, the irregular ellipsoidal shape of potatoes makes precise cutting impossible and can damage the eyes. There is an urgent need for those skilled in the art to develop an intelligent directional identification and automatic cutting device for potato seed tubers, capable of precise automatic cutting after identifying the eyes.
