Garlic directional sowing device and method based on machine vision

Abstract

The invention discloses a garlic directional sowing device and method based on machine vision. The device comprises seed shifting and discharging devices, wherein a garlic seed outlet of each seed shifting and discharging device is connected with a first end of a corresponding garlic seed transmission channel, and a second end of each garlic seed transmission channel is arranged at a garlic seed inlet of a corresponding garlic seed feature recognition and directional sowing mechanism; an image collector is correspondingly arranged right above each garlic seed feature recognition and directional sowing mechanism, and an image collection end of each image collector faces the interior of the corresponding garlic seed feature recognition and directional sowing mechanism and is used for collecting posture information photos of garlic seeds; and the garlic seed feature recognition and directional sowing mechanisms recognize and adjust the posture of the garlic seeds according to the posture information picture. According to the garlic directional sowing device and method, secondary seed shifting and discharging of garlic, directional and ordered transmission of garlic seeds, image recognition and directional sowing can be completed at a time, the planting agronomic requirement that bulbil of the garlic seeds faces upwards is met, space and size occupied by the garlic directional sowing device are greatly reduced due to the intensive design, the integrality is high, and mechanical and intelligent sowing of the garlic is met.

Description

technical field [0001] The present application relates to the technical field of agricultural machinery, in particular to a device and method for directional garlic sowing based on machine vision. Background technique [0002] The annual output of garlic in our country is increasing day by day. The annual planting area is more than 10 million mu, which is more than 60% of the world's garlic planting area and accounts for two-thirds of the world's garlic planting area. Garlic has become an important economic crop in my country. In addition to supplying domestic mass consumption, the garlic grown in my country also occupies an important position in foreign trade exports, and most of the products are exported to Russia, Japan and other foreign regions. When sowing garlic, it is necessary to meet the agronomic requirements of garlic scale buds facing upwards. Research data show that the yield and quality of mature garlic will be adversely affected after garlic scale buds face do...

Problems solved by technology

When sowing garlic, it is necessary to meet the agronomic requirements of garlic scale buds facing upwards. Research data show that garlic scale buds face down and sow horizontally will have a negative impact on the yield and quality of mature garlic

[0003] At present, there are some garlic seeding machines in the domestic market, which can use a certain mechanical structure to sow garlic scale buds of "Cangshan" garlic with regular shape and "straight, long, hard" scale buds. The scale buds are short, curved, irregular in shape, and the "Jinxiang" garlic has an irregular center of gravity because of the presence of pinched petals. It is difficult to directional sow. Compared with "Cangshan" garlic, the planting area of ​​"Jinxiang" garlic is larger and the distribution range is wider.

[0004] However, due to the irregular shape of "Jinxiang" garlic and the lack of effective methods for identifying the direction of garlic scale buds and directional sowing devices, the garlic planting characterized by "Jinxiang" garlic in my country is still dominated by artificial planting, which is labor-intensive. , the operation efficiency is low, which seriously restricts and affects the mechanized sowing operation of garlic
