Problems solved by technology

However, this method uses dynamic recognition and the distance between the recognition area and the sugarcane box is relatively high, which is likely to cause a high recognition error rate and difficult recognition. Moreover, when the distance between the two stem nodes is relatively close, the machine's response delay will cause stem node cutting errors and reduce seed cutting. Pass rate

Embodiment 1

[0038] Such as figure 1 As shown, a whole stalk sugarcane seed cutting device includes: a cane stalk horizontal conveying mechanism, a visual processing device 8 located above the cane stalk horizontal conveying mechanism, a position calibration mechanism, and a seed cutting box 9, which is arranged on the cane stalk One side of the transverse conveying mechanism;

[0039] The cane stalk transverse conveying mechanism is used to transport the cane stalk 4 to realize the transverse movement of the cane stalk 4; the visual processing device 8 is located above the cane stalk transverse conveying mechanism to realize the image acquisition of the whole cane stalk 4; the position calibration mechanism is used for calibration The position of cane stalk 4; Seed cutting box 9 is used for cutting cane stalk 4.

[0040] Specifically, the cane stalk horizontal conveying mechanism includes a driving pulley 2, a driven pulley, and a conveyor belt 3; wherein the motor 1 is connected to the ...

Embodiment 2

[0048] Such as figure 2 As shown, a method for cutting whole stalks of sugarcane, said method utilizes any one of said whole stalk sugarcane cutting devices based on visual recognition.

[0049] A kind of whole sugarcane cutting method, comprises the following steps:

[0050] Step 1: the cane stalk 4 enters the conveyor belt 3;

[0051] Step 2: The motor 1 rotates to the left, the hydraulic cylinder 7 drives the hydraulic push rod 6 to press down, judge the press displacement of the hydraulic push rod 6, and when the preset displacement is reached, stop the press, otherwise continue to press;

[0052] Step 3: When the cane stalk touches the touch sensor 5, the motor 1 stops rotating, and the hydraulic push rod 6 rises; otherwise, the motor 1 continues to rotate leftward;

[0053] Step 4: The camera collects images of cane stalk 4;

[0054] Step 5: analyze the coordinates of each stem node;

[0055] Step 6: Judging the axial displacement gap of the cane stalk according to th...

Abstract

The invention discloses a whole sugarcane seed-cutting device and method based on visual identity, belonging to the field of agricultural planting machines. The whole sugarcane seed-cutting device comprises a sugarcane rod transverse conveying mechanism, visual processing equipment, a position calibration mechanism and a seed-cutting tank, wherein the visual processing equipment, the position calibration mechanism and the seed-cutting tank are located above the sugarcane rod transverse conveying mechanism, and the seed-cutting tank is arranged on one side of the sugarcane rod transverse conveying mechanism. A whole sugarcane rod is identified based on a visual identity technique, the position of each stem node is analyzed, and the rotation number of times of a motor is calculated in advance, so that the precise cutting of the whole rod is realized, and each cut stem rod is provided with a stem node. Aiming at the deficiencies in the prior art, the invention discloses the whole sugarcane seed-cutting device with a relatively simple structure and the functions of static identification, dynamic regulation and position calibration; and by virtue of the seed-cutting method based on thedevice, the seed-cutting precision is increased, and the yield of sugarcane seeds is guaranteed.

Description

technical field [0001] The invention relates to a device and method for cutting whole sugarcane seeds based on visual recognition, belonging to the field of agricultural planting machinery. Background technique [0002] Sugar is an important strategic material of the country, and more than 90% of it comes from sucrose. Sugarcane production is directly related to China's basic sugar supply capacity. In recent years, with the impact of foreign sugar markets and the rise of agricultural labor costs, China's sugar industry is facing industrial losses, seriously affecting the safe supply of sugar and social stability in China. The traditional sugarcane planting process is all done manually, which requires a lot of labor, high labor intensity and low efficiency. Due to the shortage of labor in recent years, labor costs have increased significantly. Therefore, accelerating the mechanization of sugarcane planting is of great significance to solve the labor shortage in sugarcane a...
