Description

Technical Field

[0001] The present disclosure relates to the technical field of mold manufacturing, and in particular to a marking processing method, device, storage medium and electronic equipment. Background Art

[0002] With the development of modern industry, higher requirements are put forward for the manufacturing of product processing molds. Molding text and patterns on the surface of products can effectively improve the competitiveness of products. There are many products whose text and patterns are arranged on the curved surface of products, which requires product processing molds to arrange and process the logo on the corresponding curved surface.

[0003] At present, after the logo is arranged according to the target logo style and size in the plane design drawing, when it is vertically projected onto the curved surface of the product processing mold, Figure 1 As shown in the figure, a certain dimension of the logo (such as height) is stretched from H to L, and due to the existence of curvature, the actual processed logo size is more severely deformed and does not meet the design requirements. In order to ensure that the logo size projected onto the curved surface meets the requirements, the flat logo needs to be compressed before being projected onto the curved surface.

[0004] In related technologies, such as Figure 2 As shown, the original logo is rotated according to the normal angle of the arc surface to obtain the rotated logo; the rotated logo is projected onto the arc surface along the normal line direction to obtain the projected logo on the arc surface; the projected logo is vertically projected onto the logo plane to obtain the compressed logo, thereby obtaining the compression ratio. However, when the logo is arranged along the circumference and the logo compression direction is in the radial direction of the circumference, this method depends on the radial direction and cannot arrange the entire circle of logos at the same time. The logo needs to be cut into many parts, compressed and projected, and then spliced, but joint marks will appear, which does not meet the design requirements; and due to the curvature of the arc surface, there is still a certain error in the size of the rotated logo and the projected logo on the arc surface, resulting in a certain error in the size of the processed logo and the design requirements. Summary of the invention

[0019] The ratio of the projection length to the sum of the first identification length and the second identification length is used as the identification compression ratio.

[0020] In some embodiments, compressing the original identifier in the identifier compression direction based on the identifier compression ratio includes:

[0021] The preset reference position is kept unchanged, and the original mark is compressed in the mark compression direction toward the preset reference position.

[0048] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0050] Figure 3 This is a flow chart of a method for processing a logo provided by an embodiment of the present disclosure. This method is applicable to the case where logos on a logo plane are compressed when typeset logos such as text and / or patterns on a curved surface, and can be applied to the processing of logos on curved surfaces of product processing molds (such as tire side panels). This method can be executed by a logo processing device, which can be implemented in software and / or hardware. Figure 3 As shown, the method comprises the following steps:

[0051] S110, obtaining a preset reference position on the marking plane, and an original marking length between at least one marking point of the original marking and the preset reference position.

[0052] Among them, the preset reference position overlaps with the original mark, and the length of the original mark is the length along the mark compression direction and is greater than 0.

[0053] The original logo is arranged on the logo plane according to the design requirements. The original logo can be text or pattern. The logo plane can be arranged with only text, only pattern, or both text and pattern, depending on the design requirements. The preset reference position is pre-set by the designer as the reference of the identification point on the original logo, and the logo plane is matched with the target arc surface through projection to the target arc surface, so that the identification point on the logo plane is accurately projected on the target arc surface.

[0054] In addition, the overlap of the preset reference position and the original mark should be understood as the overlap of the preset reference position and the area where the original mark is located. Along the mark compression direction, the preset reference position can be located at one end of the original mark or between the two ends of the original mark. In some embodiments, when the preset reference position is located at one end of the original mark, any point on the original mark except the preset reference position can be selected as the mark point, and the length between the mark point and the preset reference position is taken as the original mark length. In other embodiments, when the preset reference position is located between the two ends of the original mark, a mark point can be selected on both sides of the preset reference position, and the sum of the lengths between the two mark points and the preset reference position is taken as the original mark length.

[0055] Exemplarily, for the case where the preset reference position is located between the two ends of the original marker, the preset reference position divides the original marker into a first marker part and a second marker part in the marker compression direction, and the original marker length includes the first marker length and the second marker length; obtaining the original marker length between at least one marker point of the original marker and the preset reference position includes: obtaining at least one pair of marker point pairs, wherein the marker point pair includes a first marker point on the first marker part and a second marker point on the second marker part; determining the length between the first marker point and the preset reference position along the marker compression direction as the first marker length, and the length between the second marker point and the preset reference position along the marker compression direction as the second marker length.

[0056] S120, projecting the preset reference position onto the target arc surface along a preset projection direction to obtain a projection reference position.

[0057] The preset projection direction can be perpendicular to the identification plane, or intersect with the identification plane but not perpendicular, and is set according to the actual projection requirements. The projection reference position is obtained by projecting the preset reference position, thereby establishing the corresponding relationship between the identification plane and the target arc surface, and then determining the projection position of the identification point on the target arc surface that meets the design requirements based on the projection reference position on the target arc surface.

[0058] S130, taking the projection reference position as the starting point, making an arc on the target arc surface along the curvature direction of the target arc surface.

[0059] The position of the arc relative to the projection reference position is the same as the position of the corresponding identification point relative to the preset reference position, and the arc length of the arc is equal to the original identification length corresponding to the corresponding identification point. For example, if the identification point on the identification plane is located on the left side of the preset reference position, then the corresponding arc on the target arc surface is also located on the left side of the projection reference position, and the arc length of the arc is equal to the original identification length corresponding to the corresponding identification point, so that the projection position of the identification point on the target arc surface meets the design requirements.

[0060] Exemplarily, based on S110, the arc includes a first arc and a second arc, the position of the first arc relative to the projection reference position is the same as the position of the first identification point relative to the preset reference position, and the arc length of the first arc is equal to the first identification length; the position of the second arc relative to the projection reference position is the same as the position of the second identification point relative to the preset reference position, and the arc length of the second arc is equal to the second identification length. In the case where the identification point pair includes a first identification point on the first identification part and a second identification point on the second identification part, the first arc and the second arc are made on the target arc surface respectively in the above manner, so that the end point of the first arc corresponds to the projection position of the first identification point on the target arc surface that meets the design requirements, and the end point of the second arc corresponds to the projection position of the second identification point on the target arc surface that meets the design requirements.

[0061] S140: Determine a logo compression ratio based on the original logo length and the projection length of the arc along a preset projection direction on a preset plane.

[0062] Among them, the preset plane is parallel to or coincides with the identification plane.

[0063] Exemplarily, based on the original logo length and the projection length of the arc along the preset projection direction on the preset plane, the logo compression ratio is determined, including: determining a first projection point of the end point of the first arc on the preset plane along the preset projection direction, and a second projection point of the end point of the second arc on the preset plane along the preset projection direction; determining the length between the first projection point and the second projection point along the logo compression direction as the projection length; and taking the ratio of the projection length to the sum of the first logo length and the second logo length as the logo compression ratio.

[0064] It should be noted that multiple identification point pairs can be obtained to obtain multiple identification compression ratios, and the average of the multiple identification compression ratios is taken as the final identification compression ratio to further reduce the error.

[0065] S150: compress the original logo in the logo compression direction based on the logo compression ratio.

[0066] In some embodiments, based on the logo compression ratio, the original logo is compressed in the logo compression direction, including: keeping the preset reference position unchanged, and compressing the original logo in the logo compression direction toward the preset reference position. Exemplarily, along the logo compression direction, the preset reference position is located between the two ends of the original logo. At this time, when compressing the original logo, the preset reference position is kept unchanged, and the original logo is compressed from one end of the original logo to the preset reference position according to the logo compression ratio, and at the same time, the original logo is compressed from the other end of the original logo to the preset reference position according to the logo compression ratio, so as to achieve compression of the original logo. As a result, each logo is compressed based on the preset reference position, so that the arrangement of the compressed logos is more neat.

[0067] Based on the above technical solution, in a specific embodiment of the present disclosure, for the tire side plate, it is necessary to project the logo on the logo plane onto the curved surface of the tire side plate and perform logo processing; for the tire side plate, it is necessary to compress the logo on the logo plane in height. Figure 4 , the height of the original mark is H, the preset reference position O is selected, and the marking points at both ends of the original mark are obtained in the height direction, namely, the marking point A and the marking point B. In the height direction, the length between the marking point A and the preset reference position O is H1, and the length between the marking point B and the preset reference position O is H2. The preset reference position O is vertically projected onto the arc surface of the tire side plate to obtain the projection reference position o. On the arc surface of the tire side plate, with the projection reference position o as the starting point, an arc oa with an arc length of L1 is made on the corresponding side of the marking point A, and L1 is equal to H1. With the projection reference position o as the starting point, an arc ob with an arc length of L2 is made on the corresponding side of the marking point B, and L2 is equal to H2. The arc oa and the arc ob are vertically projected onto a preset plane parallel to the marking plane, and the projection point a' of point a and the projection point b' of point b are obtained on the preset plane, thereby obtaining the length h between the projection point a' and the projection point b' in the height direction, and then the marking compression ratio is obtained based on H and h as h / H.

[0068] In summary, the identification processing method provided by the embodiment of the present disclosure projects the preset reference position on the identification plane onto the target arc surface along the preset projection direction to obtain the projection reference position, and on the target arc surface, an arc is made on the target arc surface along the curvature direction of the target arc surface with the projection reference position as the starting point, and the arc length is equal to the original identification length between the identification point of the original identification on the identification plane and the preset reference position, so that the arc is projected on a preset plane parallel to or overlapping with the identification plane along the preset projection direction, and the length from the identification point of the compressed original identification to the preset reference position, i.e., the projection length, can be obtained. Thus, the identification compression ratio is determined based on the original identification length and the projection length, and the original identification is compressed in the identification compression direction based on the identification compression ratio, so that when the compressed identification is projected onto the target arc surface along the preset projection direction, the length of the projected identification in the curvature direction of the target arc surface is equal to the length of the original identification in the identification compression direction (i.e., the original identification length). Therefore, the technical solution of the present disclosure can make the identification size projected onto the target arc surface meet the design requirements. Furthermore, the technical solution disclosed in the present invention determines the logo compression ratio by relying on the preset projection direction when projecting the logo. Even if the logos are arranged along a circle, it is unrelated to the radial direction of the circle. It is only necessary to project the logos compressed on the logo plane simultaneously along the preset projection direction onto the target arc surface according to the logo compression ratio, so that the logos on the entire target arc surface can be arranged at one time to avoid joint marks.

[0069] In some embodiments, before obtaining the preset reference position on the identification plane and the original identification length between at least one identification point of the original identification and the preset reference position, the method further includes: discretizing the original identification to obtain multiple identification points. In this way, by discretizing the original identification into multiple identification points, it is easy to identify and obtain the identification points.

[0070] In some embodiments, after compressing the original logo in the logo compression direction based on the logo compression ratio, the method also includes: projecting the new logo obtained after compressing the original logo onto the target arc surface along a preset projection direction; based on the projection of the new logo on the target arc surface, processing the new logo on the target arc surface.
