[0022] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed or can optionally include other steps or units inherent to the process, method, product or device.

[0024] In this document, the term "embodiment" means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The control function of the current mowing device is relatively simple, and cannot realize mowing of an arbitrary pattern according to user preferences, and cannot reasonably plan the mowing area.

[0026] To solve the above problems, the embodiment of the present application provides a mowing method and related device, which will be described in detail below in combination with the drawings.

[0027] Please refer to Fig. 1, which is a system architecture diagram of a mowing system provided by the embodiment of the present application. As shown in Fig. 1, the mowing system 100 comprises a pattern design module 10, a mowing device 20 and a mowing control module 30, wherein the above modules are communicatively connected to each other. The pattern design module 10 is a platform for users to design patterns, for example, a target pattern can be selected from existing patterns in the pattern design module 10 for combination or a certain pattern can be selected alone, a pattern can be imported from outside, a canvas interface can be entered to design a pattern by oneself, etc. The mowing device 20 is used to mow grass according to a mowing path sent by the mowing control module 30. The mowing control module 30 is used to acquire a pattern designed by the pattern design module 10 and related pattern information, for example, information such as size, position and color of each pattern on the lawn, and is used to acquire related information of the mowing device 20, such as the cutting width of the mowing device. Then, the acquired information is analyzed to determine the display mode of the lawn pattern, so as to determine the position requiring mowing operation. Finally, the mowing path is determined according to the position requiring mowing, so that the mowing device 20 mows the lawn based on the mowing path.

[0028] Please refer to Fig. 2, which is a flowchart of a mowing method provided by the embodiment of the present application. The method comprises the following steps.

[0029] S210, acquiring lawn map information, wherein the lawn map information comprises a plurality of lawn patterns.

[0030] Specifically, the lawn map information comprises a lawn map. The acquiring of the lawn map information comprises: starting a mowing pattern setting interface when a setting pattern instruction is received, and displaying the lawn map to the mowing pattern setting interface. The mowing pattern setting interface is used for target users to customize pattern information, wherein the pattern information comprises pattern color, pattern shape, pattern area, pattern position and pattern proportion. The pattern color is used to indicate the height of the corresponding pattern. The pattern information is received. The pattern information is preprocessed to obtain the lawn map information.

[0031] When the mowing pattern setting interface is started, the pattern setting interface displays the lawn image information determined by the user, i.e., the lawn map is displayed on the pattern setting interface. Please refer to FIG. 3, which is a schematic diagram of a lawn map according to an embodiment of the present application. As shown in FIG. 3, the lawn map includes a first lawn 301, a second lawn 302, and a third lawn 303. The user randomly selects the first lawn 301, the second lawn 302, and the third lawn 303 to design the pattern. For example, if the user selects the first lawn 301 to design the pattern, the user can click the first lawn 301 in the pattern setting interface to enter the setting interface.

[0032] The mowing pattern setting interface includes a plurality of common lawn patterns. Specifically, the mowing pattern setting interface stores the previously used patterns and the drawn patterns. When designing the lawn pattern, the user can select a desired pattern from the existing patterns through the mowing pattern setting interface, import an external picture, enter the canvas interface to design the pattern, and the like. The user can also combine and splice the above patterns to achieve the final pattern effect. When designing the pattern, the user can also customize the size, color, and specific position of the pattern on the lawn map. Please refer to FIG. 4, which is a schematic diagram of a pattern setting interface according to an embodiment of the present application. As shown in FIG. 4, the pattern setting interface 40 includes an imported pattern 41, a custom pattern 42, and a selectable pattern 43. The imported pattern 41 is used for the user to import an external pattern. The selectable pattern 43 includes a plurality of common simple patterns, such as a smiley face, a rectangle, a sun, a moon, a heart, and the like, so that the user can directly select the pattern. The user can also click the button of the custom pattern 42 to enter the drawing pattern interface. As shown in FIG. 4, assuming that the lawn has an irregular shape, including a non-lawn area 421, a moon pattern 422, a cloud pattern 423, and a drawn pattern 424. Through the user-defined lawn pattern, the user can realize the trimming of any pattern according to his / her preference.

[0033] Further, please refer to FIG. 5, which is a schematic diagram of mowing according to an embodiment of the present application. As shown in FIG. 5, the user defines the lawn pattern on the fourth lawn 51, including a heart pattern 53 and a wave pattern 52. Assuming that the interval distance between the heart pattern 53 and the wave pattern 52 is less than the cutting width of the mowing device, it is determined that the display mode of the heart pattern 53 and the wave pattern 52 is concave, the position of the heart pattern 53 and the wave pattern 52 is determined as the position to be mowed, and the mowing path is generated, so that the mowing device mows the heart pattern 53 and the wave pattern 52 according to the generated mowing path. The arrow direction in FIG. 5 represents the cutting direction of the mowing device. Further, different cutting heights can be set according to the different colors of the heart pattern 53 and the wave pattern 52.

[0034] The lawn in the lawn map can be a lawn that has not been mowed. When the user customizes the pattern in the mowing pattern setting interface, the user can directly set the designed pattern on the lawn so as to view the pattern effect and directly modify the pattern on the image of the lawn if the user is not satisfied with the pattern effect. The pattern effect can be viewed from multiple angles.

[0035] If the user needs to modify the pattern on the lawn, the lawn in the lawn map can also be a lawn with a lawn pattern. Therefore, when the user customizes the pattern in the mowing pattern setting interface, the user needs to design the pattern in combination with the height of the current lawn and the pattern of the current lawn.

[0036] Specifically, the pattern information is preprocessed, including: determining the range of the height of the lawn corresponding to each pattern color in the pattern color; adjusting the proportion of the pattern if the proportion of the pattern is greater than a preset pattern proportion; and adjusting the position of the pattern if the position of the pattern exceeds a preset position.

[0037] When the user uploads the pattern information, the pattern is first desaturated, for example, the image information is converted to grayscale. The grayscale value corresponding to the pattern is then obtained. The same grayscale value can be used to represent the same color. For example, the higher the grayscale value, the higher the height of the corresponding pattern. The format of the image is then adjusted. For example, whether the proportion of the user-defined pattern is appropriate is determined according to a preset pattern proportion. The preset pattern proportion can be a reasonable proportion range. Whether the position of the user-defined pattern is appropriate is also determined according to a preset pattern position range.

[0038] It can be seen that, by preprocessing the user-defined pattern, the pattern can be set within a reasonable range of the lawn, thereby enhancing the aesthetic appearance of the lawn pattern.

[0039] S220, obtaining the distance between any two adjacent lawn patterns in the plurality of lawn patterns, to obtain a plurality of interval distances.

[0040] Referring to FIG. 6, FIG. 6 is a schematic diagram of a lawn pattern, as shown in FIG. 6, four lawn patterns exist in the fifth lawn 60, which are a first lawn pattern 601, a second lawn pattern 602, a third lawn pattern 603, and a fourth lawn pattern 604. The interval distances between the first lawn pattern 601 and the second lawn pattern 602, the third lawn pattern 603, and the fourth lawn pattern 604 are obtained, respectively. The interval distances between the second lawn pattern 602 and the third lawn pattern 603 and the fourth lawn pattern 604 are obtained, respectively. The interval distance between the third lawn pattern 603 and the fourth lawn pattern 604 is obtained. The interval distance can be the shortest distance between two lawn patterns without contacting other lawn patterns.

[0041] S230, obtaining a cutting width of the mowing device.

[0042] S240, obtaining a difference between each interval distance and the cutting width, to obtain a plurality of target differences.

[0043] For example, as shown in FIG. 6, six interval distances are obtained according to four lawn patterns, and the six interval distances are subtracted from the obtained cutting width to obtain six target differences.

[0044] S250, determining a working area according to the plurality of target differences, the working area being used to indicate an area requiring mowing operation.

[0045] Specifically, determining the working area according to the plurality of target differences includes: in a case where there is a target difference less than zero in the plurality of target differences, determining a pattern area as the working area, the pattern area being an area where the plurality of lawn patterns are located in a lawn map, the lawn map information including the lawn map; and in a case where all target differences are not less than zero in the plurality of target differences, determining a non-pattern area as the working area, the non-pattern area being an area other than the area where the plurality of lawn patterns are located in the lawn map.

[0046] In a case where there is an interval distance less than the cutting width, the lawn pattern is recessed, and if the lawn pattern is highlighted, the cutting width will be much larger than the effect designed by the user when the mowing device passes between the patterns, and even affect the shape of the pattern, so that the mowing effect does not meet the user's expectation. In a case where all interval distances are not less than the cutting width, an external mowing mode can be used preferentially, so that the lawn is neat and beautiful, and the overall landscape effect is improved.

[0047] It can be seen that, in determining the mowing area, the cutting width of the mowing device and the distance between the patterns are considered, so as to facilitate mowing by the mowing device, thereby improving the mowing effect for the patterns.

[0048] Specifically, before determining the non-pattern area as the working area, the method further includes: performing contour detection on the plurality of lawn patterns to obtain a first contour curve and a second contour curve for each lawn pattern; obtaining a line segment width between the first contour curve and the second contour curve; and determining the working area according to the line segment width.

[0049] Referring to FIG. 7, FIG. 7 is a schematic diagram of another lawn pattern according to an embodiment of the present application. As shown in FIG. 7, when the contour of the lawn pattern is detected, an inner contour curve 702 and an outer contour curve 701 are used to form a lawn pattern A, and then the width of the lawn pattern A is determined according to the inner contour curve 702 and the outer contour curve 701. If the lawn pattern is irregular and has multiple line segment widths, the most narrow line segment width can be used to determine whether the lawn pattern is highlighted or recessed.

[0050] Specifically, after the line segment width between the first contour curve and the second contour curve is obtained, the method further includes: determining a comparison result of the line segment width and the cutting width; obtaining a first cutting path based on a first display mode according to the comparison result that the line segment width is greater than the cutting width, the first display mode being to recess the multiple lawn patterns in the lawn map; obtaining a second cutting path based on a second display mode, the second display mode being to highlight the multiple lawn patterns in the lawn map; determining a cutting path with the shortest distance between the first cutting path and the second cutting path as a target cutting path; and determining the work area according to the target cutting path.

[0051] In the case that the line segment width is less than or equal to the cutting width, the non-pattern area is determined as the mowing area, so as to ensure the cutting effect of the pattern. In the case that the line segment width is greater than the cutting width, different cutting paths can be determined according to different cutting modes based on the pattern designed by the user, and the area on the lawn map corresponding to the cutting path with the shortest distance is determined as the mowing area, so as to improve the cutting efficiency of the mowing device.

[0052] In the case that the line segment width is greater than the cutting width, the number of colors in the multiple designed lawn patterns can also be determined, and each color corresponds to a cutting height. The more colors, the greater the cutting complexity. The mowing area is determined according to the number of colors of the lawn pattern. For example, in the case that the number of colors of the multiple lawn patterns is greater than a preset number of colors, the pattern area is determined as the mowing area. In the case that the number of colors of the multiple lawn patterns is not greater than the preset number of colors, the non-pattern area is preferentially selected as the mowing area, so as to improve the overall landscape effect.

[0053] Specifically, before the non-pattern area is determined as the work area, the method further includes: receiving a mowing instruction, the mowing instruction including a display mode for each of the multiple lawn patterns, the display mode including highlighting or recessing the multiple lawn patterns in the lawn map; and determining the work area according to the mowing instruction.

[0054] If the mowing instruction of the user for the lawn pattern is received before the mowing area is determined, the lawn is mowed according to the instruction of the user, and the lawn pattern can be displayed in a three-dimensional manner on the lawn by the user selecting different display manners of the pattern, so that the user can view the pattern effect, and the mowing instruction of the user can also be selected from the above display manners. The mowing is performed by receiving the instruction of the user, the user experience is enhanced, and the cutting effect of the pattern is closer to the demand of the user.

[0055] It can be seen that, in the embodiment, the display types of the lawn patterns are reasonably planned according to the interval distance and the cutting width, and the mowing area is matched according to different display types, so as to guarantee the cutting effect of the pattern and improve the mowing efficiency.
