Problems solved by technology

In the existing technology, it mainly relies on manual inspection to check the position of missing seedlings, or manually marks the position of missing seedlings according to the photos taken during the drone inspection, or can only automatically identify the position of missing seedlings for crops that are planted in strict straight lines
[0004] In the process of realizing the present invention, the inventor found that the prior art has the following defects: the degree of automation is low, and it is impossible to quickly identify the position of the lack of seedlings
In addition, in agricultural production practice, it is impossible to ensure that crops are planted in a strict straight line. For crops that are not planted in a strict straight line, it is impossible to automatically identify the position of missing seedlings.

Embodiment 1

[0072] Figure 1a It is a flow chart of a method for marking lack of seedlings provided by Embodiment 1 of the present invention. This embodiment is applicable to situations where it is necessary to automatically mark crops lacking seedlings in farmland images. This method can be executed by a device for marking lacking seedlings. The device can be realized by software and / or hardware, and can generally be integrated in a server.

[0073] like Figure 1a As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0074] S110. Generate a crop binary image according to the farmland image, and obtain the planting row main direction according to the crop binary image, and extract a plurality of crop connected domains included in the crop binary image.

[0075] Wherein, the farmland image may be an image taken when a drone patrols the farmland. In a specific example, Figure 1b Provides a schematic representation of a f...

Embodiment 2

[0102] Figure 2a It is a flow chart of a method for marking lack of seedlings provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, the embodiment of the present invention includes the process of generating a crop binary image based on a farmland image and obtaining planting rows based on a crop binary image. The process of the main direction, the process of obtaining the planting row area, and the process of marking the lack of seedlings in the planting row area are further specified.

[0103] Correspondingly, such as Figure 2a As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0104] S210. Generate a vegetation binary map according to the vegetation points included in the farmland image.

[0105] Among them, the vegetation point indicates that the pixel point in the image represents vegetation, and whether the pixel point in the image is a vegetation point ...

Embodiment 3

[0172] image 3 It is a flow chart of a replanting method provided by Embodiment 3 of the present invention. This embodiment is applicable to the situation of replanting seedling-deficient areas in farmland. The method can be performed by a replanting device, which can be composed of It is realized by software and / or hardware, and is generally integrated in computer equipment or agricultural machinery equipment.

[0173] like image 3 As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0174] S310. Acquire at least one farmland image that matches the set planting area, and use the method for marking lack of seedlings as described in the embodiment of the present invention to determine the lack of seedlings in the crop binary image corresponding to each of the farmland images.

[0175] Wherein, the set planting area is a planting area where replanting operation needs to be performed. After obtaining the pic...

Abstract

The invention discloses a seedling missing marking method and device, computer equipment and a storage medium. The method comprises the following steps: generating a crop binary image according to a farmland image, obtaining a planting row main direction according to the crop binary image, and extracting a plurality of crop connected domains included in the crop binary image; obtaining at least one planting row area according to the crop binary image and the planting row main direction; and according to the distance between the adjacent crop connected domains in each planting row area, carrying out seedling missing marking in the planting row area. According to the technical scheme of the invention, the method can achieve the automatic recognition and marking of the seedling missing position of crops which are planted in a relatively straight line.

Description

technical field [0001] Embodiments of the present invention relate to image recognition technology, and in particular to a method, device, computer equipment and storage medium for marking lack of seedlings. Background technique [0002] my country is a large agricultural country, and the number of crop plants has a significant impact on crop yield. Only when the density of crop plants reaches a certain value can crop yield be increased. [0003] Affected by factors such as the germination rate of crop seeds, field conditions, planting machinery precision, and pests and diseases, crop plants often appear missing. In the existing technology, it mainly relies on manual inspection to check the location of missing seedlings, or manually marks the location of missing seedlings according to the photos taken during the drone inspection, or can only automatically identify the location of missing seedlings for crops that are planted in strict straight lines. [0004] In the process ...
