Specifically, the information providing device for automatic grass threading may analyze attribute information of a structure point within at least one line segment that is thinned (S4100).
According to the embodiment, the information providing apparatus for automatic grass threading may classify the structure points of the line segment thinned by the first analysis unit into at least one of the end point, the connection point, and the branch point. Wherein the end point is a point located at the end of the line segment, the connection point is a point constituting the line segment, and the branch point is a point at an intersection position of at least 3 line segments.
Then, the automatic grass threading information providing device analyzes at least one piece of thinned line segment information based on the structure point information (S4500).
According to an embodiment, the information providing device for automatic grass threading classifies structure points located at both ends of a line segment thinned by the second analyzing unit according to attributes. For example, the information providing device for automatically putting on grass can classify the plurality of structure points into at least one of a first line segment, a second line segment and a third line segment. In this case, the first line segment may be at least one thinned line segment in which the structure points at both ends are each constituted by an end point, and the second line segment may be one thinned line segment in which the structure points at both ends are each constituted by an end point and a branch point. Also, the third line segment may be at least one thinned line segment in which the structure points at both ends are each constituted by branch points.
After the analysis of the at least one thinned line segment, the information providing apparatus for automatically putting through grass may generate a grass-putting image (S5000). The grass-piercing image may be a line segment image of a danqing pattern reflecting the analyzed line segment information. For example, the size of the grass threading image may correspond to the size of the grass pad to be threaded.
Specifically, the information providing device for automatic grass cutting can provide the danqing pattern in the grass cutting image in a single pattern or a repeated pattern according to the input signal of the user.
The procedure of generating the grass-wearing image in the automatic grass-wearing information providing device for providing the danqing grain on which the line segment information is reflected will be described in more detail with reference to fig. 9 below.
Fig. 9 is a flowchart of the steps of generating a grass trimming image in the automatic grass trimming information providing method according to the embodiment of the present invention.
Referring to fig. 9, the information providing apparatus for automatic grass cutting may receive an input signal of a user (S5100).
According to an embodiment, in a case where the signal input from the user is the first input signal (S5300), the automatic grass planting information providing apparatus may generate a grass planting image including a single danish grain within the corrected grass drawing image (S5900).
According to another embodiment, in the case where the signal input from the user is the second input signal (S5300), the automatic grass mowing information providing apparatus may perform a grass folding simulation (S5500).
The grass folding simulation may iteratively perform a symmetric shift and replication of a single danish grain within the corrected draft image. Thus, the information providing device for automatic grass cutting can generate a repetitive pattern (S5700).
Thereafter, the information providing apparatus for automatic grass cutting may generate a grass cutting image including a repetitive pattern (S5900). In this case, the size of the grass threading image may correspond to the size of the grass pad to be subjected to grass threading.
Referring again to fig. 8, the information providing apparatus for automatic grass threading may generate hole-linking information for making grass out of the grass sheet (S6000). The hole-connecting information may be generated using the analyzed line segment information, and may include positions of holes to be punched in the paper, diameters of the holes, and intervals between the holes.
For example, the information providing apparatus for automatically dressing grass may calculate the curvature based on the at least one piece of line information. In this case, according to an embodiment, when the curvature is greater than or equal to a predetermined value, the automatic grass-mowing device may set the interval between the consecutive holes to be narrow.
In contrast, according to another embodiment, when the curvature is equal to or smaller than a predetermined value, the automatic grass threading device sets the interval between the continuous holes to be wide.
Also, the information providing apparatus for automatic grass cutting may generate a perforated image (S6000). The perforation image may be an image in which the grass-piercing image reflects the hole-connecting information.
Thereafter, the automatic information providing apparatus for dressing grass may transmit the generated hole information or perforation image to the grass dressing apparatus (S7000). In this case, the guidance information providing device for grass cutting can convert the hole-linking information or the perforation image reflecting the hole-linking information into information compatible with the grass cutting device.
