Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that the "plurality of columns" and "at least one" mentioned herein mean two or more.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
The trademark cutting method provided by the application can be applied to the application environment shown in fig. 1. The server 102 is communicated with the trademark cutting device 104 through a network, the server 102 is connected with the display screen 106 through the network, a user can perform template correction, set search areas, customize trademark cutting paths and other operations on the display screen 106, the trademark cutting device 104 is provided with a cutting head for cutting trademarks, and the cutting head is provided with a camera device for extracting trademark local images. The server 102 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, there is a flow chart of a trademark cutting method, which includes the steps of:
Wherein, full-page trademark comprises a plurality of columns of trademarks, and each column of trademarks comprises at least one trademark.
The trademark to be cut can be a trademark to be cut in the full-page trademarks.
The template search area may be a local area in the whole trademark area, and the area is smaller than the whole trademark area. For example, the area where the mark such as a letter, a LOGO, a character, a pattern, etc. on the trademark is located may be set as the template search area; each quotient is labeled with its corresponding template search area.
For example, as shown in fig. 3, which is a schematic diagram of an entire trademark, the entire trademark includes 3 columns, each column includes 3 trademarks, and the first column, the second column and the third column have different trademark deformation degrees. For example, the degrees of deformation of the trademark S11, the trademark S21, and the trademark S31 may be different when the trademark S11, the trademark S12, and the trademark S13 are defined as a first column, the trademark S21, the trademark S22, and the trademark S23 are defined as a second column, and the trademark S31, the trademark S32, and the trademark S33 are defined as a third column. The template search area of trademark S11 may be set as S1120, similarly the template search area of trademark S21 may be set as S2120, and the template search area of trademark S31 may be set as S3120, and thus the set template search areas are different from each other in order to distinguish trademarks of different deformation degrees.
In the specific implementation, the cutting position of the trademark to be cut can be determined, the cutting position is provided with a corresponding template searching area, and the template searching area of the trademark to be cut can be determined according to the cutting position. For example, after cutting a trademark, the trademark cutting device comes to the cutting position of the next trademark, and according to the cutting position, the template search area corresponding to the position is called, so that the template search area of the trademark to be cut is determined.
And 204, extracting an image in the template searching area in the trademark to be cut as a local trademark image.
In the specific implementation, after the template search area of the trademark to be cut is determined, the image in the template search area on the trademark to be cut is collected through the camera on the cutting head, and the image is used as a local image of the trademark to prepare for image matching in the next step.
For example, in trademark S11, when the template search area is determined as S1120, the server 102 transmits an image capture instruction to the image capture apparatus, and the image capture apparatus receives the image capture instruction, captures the image in the template search area S1120 to obtain an image in the template search area S1120, and records the image as a trademark partial image of trademark S11 as S1120'.
And step 206, matching the trademark local image with a reference trademark local image corresponding to the template searching area of the trademark.
The reference trademark local image represents an image corresponding to a template search area set for a trademark.
In specific implementation, after a trademark local image of a trademark to be cut is obtained, the server 102 matches the trademark local image with an image corresponding to a template search area set for the trademark to be cut, that is, identifiers such as patterns, letters and symbols in the two images can be compared, whether the identifiers and positions of the identifiers in the template search area are consistent or not is judged, and the trademark template is selected and corrected according to a judgment result.
For example, if the template search region provided for the trademark S11 is denoted as S1122, the image corresponding to the region S1122 is the reference trademark partial image and is denoted as S1122'. The matching of the trademark partial image with the reference trademark partial image corresponding to the template search area is to match the trademark partial image S1120 'of the trademark S11 with the reference trademark partial image S1122' and determine whether or not the pattern, the pattern shape, the pattern size, the pattern position, and the like in the two images match each other so as to select the corrected trademark template in accordance with the determination result.
Wherein the original trademark template may be a template for cutting an undeformed trademark.
The number of the corrected trademark templates can be multiple, and each trademark is marked with the corresponding trademark template.
Wherein, the deformation degree of each trademark may be the same, and the same modified trademark template may be used for trademarks with the same deformation degree.
In specific implementation, the server 102 matches a trademark local image extracted from a template search area corresponding to the position of the trademark to be cut with a reference trademark local image corresponding to the template search area, and when the two images are matched, executes a template calling operation to call a corrected trademark template preset for the template search area as the corrected trademark template of the trademark to be cut.
For example, when the trademark partial image S1120 'of the trademark S11 is judged to match the pattern, the pattern shape, the pattern size, the pattern position, and the like in the reference trademark partial image S1122', the two images are matched, and the corrected trademark template preset for the template search area, that is, the corrected trademark template S112 is acquired.
In practice, the modified trademark template may be set in various ways. In one of the ways of setting the modified trademark template, the user may create a corresponding original trademark template for the entire plate of trademarks, and then modify the created original trademark template for the degree of deformation of each column of trademarks to obtain the modified trademark template.
The original trademark template may be modified in various ways depending on the degree of distortion of the trademark, for example, the original trademark template may be used first to cut the trademark to be cut, the cut trademark may be incomplete, the correction of the original trademark template is to be a curve which separates the template contour after the trademark is cut from the actual outer contour of the trademark, i.e. the convex curve is contracted, the curve with a closer distance, i.e. the concave curve is expanded to obtain a trademark template matched with the actual outer contour of the trademark, and finally the trademark template is expanded for a certain distance, the resulting trademark template is used as a modified trademark template with the sewing position of the reserved trademark, as shown in figure 3, the circular arc solid line of the trademark outer ring represents the actual outer contour of the trademark, and the circular arc dotted line represents the trademark contour obtained after expanding a certain distance.
And step 210, cutting the trademark to be cut by adopting the corrected trademark template.
In specific implementation, after obtaining a corrected trademark template of a trademark to be cut, the server 102 sends a cutting instruction to the trademark cutting device 104, and after receiving the cutting instruction, the trademark cutting device 104 cuts the trademark to be cut by using the obtained corrected trademark template.
For example, when the corrected trademark template S112 of the trademark S11 is obtained, the trademark cutting device 104 receives the cutting command, and cuts the trademark S11 using the corrected trademark template S112.
In the trademark cutting method, a template searching area of the trademark to be cut is determined in the full-page trademark, an image in the template searching area in the trademark to be cut is further extracted, the extracted image is matched with a reference trademark image corresponding to the template searching area, and a corrected trademark template is selected according to a matching result; and if so, acquiring a corrected trademark template preset for the template search area so as to acquire a corrected trademark template corresponding to the trademark to be cut, and finally cutting the trademark to be cut by adopting the corrected trademark template. According to the method, the to-be-cut trademark and the corrected trademark template are mutually corresponding through the template searching area, each trademark of the whole trademark is cut by the method, each trademark in the whole trademark can be cut by the corresponding corrected trademark template, the cutting quality of the trademarks is guaranteed, meanwhile, the whole trademark is cut continuously at one time, and the trademark cutting efficiency is effectively improved.
In one embodiment, step 202 includes: determining the cutting position of the trademark to be cut; and determining a template searching area of the trademark to be cut according to the cutting position.
For example, in fig. 3, the cutting position of trademark S11 is the first row and the first column, the template search area of the cutting position is S1120, the server 102 records the cutting position by a position coordinate (x1, y1), when the cutting head moves from the initial position to the cutting position of the trademark to be cut, the position coordinate (x1, y1) of trademark S11 can be determined according to the moving distance, i.e. the cutting position of trademark S11 can be determined, and the server 102 calls the corresponding template search area according to the cutting position, so that the template search area of the trademark to be cut can be determined in the full-page trademark.
Alternatively, when the cutting of the trademark cutting device 104 is completed to the position of the trademark S21 from the cut of the trademark S11, the position coordinates (x2, y1) of the trademark S21 can be determined from the distance moved by the cutting head, the cut position of the trademark S21 can be determined, and further the template search area S2120 of the trademark S21 can be determined from the cut position.
In the embodiment, the determination of the template searching area of the trademark to be cut can be realized by determining the cutting position of the trademark to be cut, and the traditional similarity-based identification and cutting of the trademark to be cut is separated from the correspondence between the trademark to be cut and the corrected trademark template through the template searching area.
In an embodiment, before the step 304, the method further includes: and determining a trademark cutting path, and determining the cutting position of the trademark to be cut according to the trademark cutting path.
Wherein, the trademark cutting path refers to a trademark cutting sequence for cutting in the full-page trademark.
The trademark cutting path can be set by a user in a self-defined mode.
In the specific implementation, after the trademark cutting device 104 finishes cutting one to-be-cut trademark 1, the trademark cutting device 104 acquires the next trademark as the to-be-cut trademark 2 according to a set trademark cutting path, the cutting head of the trademark cutting device 104 moves to the cutting position of the to-be-cut trademark 2, the operations from step 202 to step 210 are continuously executed, that is, according to the cutting position of the to-be-cut trademark 2, the template search area 2 of the to-be-cut trademark 2 is determined, the image in the template search area 2 in the to-be-cut trademark 2 is extracted and used as the trademark local image 2, the trademark local image 2 is matched with the reference trademark local image corresponding to the template search area 2, if the trademark local image is matched, the corrected trademark template 2 preset for the template search area 2 is acquired, and the to-be-cut trademark 2 is cut by using the corrected trademark template 2.
For example, in fig. 5, a schematic diagram of a customized trademark cutting path is shown, where the trademark cutting path is: S11-S21-S31-S32-S22-S12-S13-S23-S33, the trademark cutting device 104 cuts one by one according to the trademark cutting path, and the operations from step 202 to step 210 are repeatedly executed, so that the cutting of the whole trademark is completed.
Further, after the whole trademark is cut according to the trademark cutting path, the trademark cutting path can be continuously used for cutting the next trademark without resetting a new trademark cutting path.
In one embodiment, the step of determining the cutting path of the trademark comprises: and determining the positioning point of the trademark, and sequentially connecting the positioning points to obtain the trademark cutting path.
The positioning point is a point carrying coordinate position information of a trademark.
In specific implementation, a user clicks the positioning points in sequence, and the positioning points are connected according to the clicking sequence to obtain a continuous connecting route which is used as a trademark cutting path. Further, the full-page trademark is cut according to the trademark cutting path.
There are various connection manners of the anchor points, for example, the anchor points may be connected column by column, and the anchor point closest to the last anchor point in the previous column is used as the starting point of the next column, so as to obtain an S-shaped connection route, as shown in fig. 5.
In the embodiment, the positioning points are connected in sequence to realize the self-definition of the trademark cutting path, and the method can separate the operation of cutting one row in the traditional cutting method and cutting the next row from the starting point, thereby reducing the repeated moving distance of the cutting head and saving the cutting time for cutting the whole trademark.
In one embodiment, the step of determining the location point of the trademark includes: receiving a trigger operation of a user on a template searching area of a trademark; generating a positioning point of the trademark according to the triggering operation; the trademark has a corresponding template search area.
In the specific implementation, after a user corrects an original trademark template to obtain a corrected trademark template of each trademark, setting a template search area on the corrected trademark template, wherein the same corrected trademark template can be set with the same template search area, after the template search area of each trademark is obtained, the user can generate a positioning point by clicking the template search area, so that the positioning point of each trademark is obtained, and the positioning points are connected to obtain a trademark cutting path.
For example, regarding the trademark in fig. 3, the template search area of the trademark S11 is S1120, the user clicks the template search area S1120 on the display screen to send a trigger command, the server 102 receives the trigger command to generate the position coordinates (x1, y1) corresponding to the trademark S11, and the point including the position coordinate information may be used as the anchor point of the trademark S11.
In this embodiment, the server generates the positioning point of the trademark by receiving the trigger operation of the user to the template search area of the trademark, and the determination of the position coordinates corresponding to each trademark can be realized by the method.
