Problems solved by technology

However, at present, the mechanical weeding mechanism between rice seedling rows is based on artificially judging the weed density to select the weeding depth. It has not realized the automatic identification of the weed density and position in the field and fed back the weed density and position information to the tillage depth adjustment mechanism to realize automatic cultivation.

Embodiment 1

[0062] Such as figure 1 Shown, the present embodiment provides a kind of weeding depth adjustment system, and this system is applied to cultivating weeder, and it comprises industrial camera 1, speed sensor (not shown in the figure) and computer 2, industrial camera 1, speed sensor and The computer 2 realizes the machine vision detection technology. The industrial camera 1 and the speed sensor are installed at the front of the cultivator and weeder, and are respectively connected to the computer 2. The working camera 1 is used to capture images of rice seedling crop rows, and the speed sensor is used to detect the intertillage and weeding Whether the machine is walking or not and the speed of the cultivator and weeder, the computer 2 is used to process the image of the rice seedling crop row to obtain the weed density and position information; Camera 1 can still shoot normally, and this system can also comprise ring light source (not shown in the figure), and this ring light s...

Embodiment 2

[0084] Such as Image 6 As shown, the present embodiment provides a device for adjusting the depth of tillage for weeding. The device includes an acquisition module 601, a delineation module 602, a division and recording module 603 and an adjustment module 604. The specific functions of each module are as follows:

[0085] The acquiring module 601 is configured to acquire crop row images of rice seedlings at time intervals calculated according to the driving speed of the cultivator weeding machine.

[0086] The delineation module 602 is used to complete the semantic segmentation of rice seedling pixels and inter-row weed pixels on the rice seedling crop row image, and delineate the rice seedling crop rows according to the rice seedling pixels.

[0087] The division and recording module 603 is used to classify the density of weeds according to the weed pixel value in the rice seedling crop row, and record the position information of the weeds on the rice seedling crop row image...

Embodiment 3

[0095] This embodiment provides a computer device, which can be a computer, such as Figure 8 As shown, a processor 802, a memory, an input device 803, a display 804 and a network interface 805 are connected through a system bus 801, the processor is used to provide computing and control capabilities, and the memory includes a non-volatile storage medium 806 and an internal memory 807, the non-volatile storage medium 806 stores an operating system, a computer program, and a database, the internal memory 807 provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium, and the processor 802 executes the During computer program, realize the weeding deep-plow adjustment method of above-mentioned embodiment 1, as follows:

[0096] According to the time interval calculated by the driving speed of the cultivator and weeder, the image of the rice seedling crop row is obtained;

[0097] Complete the semantic segmentation ...

Abstract

The invention discloses a weeding and tilling depth adjusting method, device and system, computer equipment and a storage medium, and the method comprises the steps: obtaining a rice seedling crop rowimage according to a time interval calculated according to the driving speed of an intertillage weeding machine; completing semantic segmentation of rice seedling pixels and inter-row weed pixels onthe rice seedling crop row image, and defining rice seedling crop rows according to the rice seedling pixels; grading the weed density according to the pixel values of the weeds in the rice seedling crop rows, and recording the position information of the weeds on the rice seedling crop row images; and controlling a tilling depth adjusting mechanism of the intertillage weeding machine to adjust the weeding tilling depth of the weeding part corresponding to the weed density grade according to the weed density grade and the position information. According to the invention, real-time identification of the density and position of weeds between rice seedling rows can be realized, corresponding weeding tilling depth adjustment is further realized, the impurity removal rate of the intertillage weeding machine is improved, and a foundation is laid for research and development design of the intelligent intertillage weeding machine between rice seedling rows.

Description

technical field [0001] The invention relates to a method, a device, a system, a computer device and a storage medium for adjusting the depth of tillage for weeding, and belongs to the technical field of automatic control of agricultural machinery equipment. Background technique [0002] Weeds in rice fields are one of the main factors leading to the decline of rice yield. According to statistics, the loss rate of rice yield caused by weeds is more than 15% every year. The use of chemical agents to kill weeds is currently the most commonly used method of weeding. However, the extensive use of herbicides has also brought many negative problems, such as weed resistance, soil and water pollution, and the reduction of rice quality. Mechanical weeding is a non-polluting weeding method. At the same time, it has the advantages of increasing oxygen, increasing ground temperature, and facilitating the growth of seedlings. Therefore, it is worth exploring the subject of mechanization,...
