Detailed Description
The embodiment of the application provides a method and a device for determining a color scheme.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method for determining a color scheme. The method of determining a color scheme may be provided with a plurality of reference colors and reference color sets; wherein the reference color set comprises at least one reference color.
In this embodiment, the reference color may be a chromatic color. For example, the reference color may be red, yellow, green, cyan, or blue. The attribute values of these reference colors may be represented by RGB, including R, G and B three color component values, respectively. Wherein, the RGB attribute values of red, yellow, green, cyan and blue can be characterized by hexadecimal color codes, and the hexadecimal color codes corresponding to these colors are "OXFF 0000", "OXFF 00", "OX 00FF 00", "OX 00 FFFF", "OX 0000 FF", respectively.
In this embodiment, the reference color set may include at least one reference color. For example, the reference color may be black or white, or may be set according to the user's own needs. In general, black or white is usually used as the reference color to avoid using a combination of colors close to black or white as a color scheme in the subsequent determination of the color scheme, since black has a heavier color, is displayed in a less harmonious manner, and white has a color too light to easily coincide with a white background in a view, so that a user may not see clearly.
FIG. 1 is a flow chart of an embodiment of a method for determining color schemes according to the present application. As shown in fig. 1, the method for determining color schemes includes the following steps.
Step S101: generating a target color circle based on the reference color; the color ring comprises colors of a first preset color type; and colors in the color ring correspond to color positions one by one.
In this embodiment, generating the target color circle based on the reference color may specifically include annularly arranging a plurality of types of the reference colors to obtain an initial color circle. Interpolation processing can be carried out on the basis of the attribute values of two adjacent reference colors in the initial color ring to obtain a plurality of discrete attribute values and colors corresponding to the discrete attribute values; the types of the colors corresponding to the discrete attribute values are equal to the first preset color type. The colors corresponding to the discrete attribute values can be arranged in a ring shape to obtain the target color circle. And the colors in the color ring correspond to the color positions one by one. For example, the reference colors are 5 kinds, which are red, yellow, green, cyan, and blue, respectively. These reference colors can be arranged circularly to obtain an initial color circle. At this time, if the first preset color type is 128, interpolation processing needs to be performed based on the attribute values of two adjacent reference colors in the initial color ring to obtain 128 discrete attribute values and colors corresponding to the discrete attribute values. Since the reference colors are 5 in kind, the initial color wheel may include 5 combinations of two adjacent reference colors, such as a combination of adjacent red and yellow, a combination of adjacent yellow and green, a combination of adjacent green and cyan, a combination of adjacent cyan and blue, and a combination of adjacent blue and red, respectively. Then, the first predetermined color type may be divided by the reference color type, i.e., 128 divided by 5, which is a value of 24 to 3. In this way, interpolation processing can be performed based on the attribute values of the combinations of the adjacent reference colors, respectively, to obtain discrete attribute values of 24, 25, and 25, respectively, and obtain a total number of discrete attribute values of 128. Therefore, the colors corresponding to the discrete attribute values can be circularly and uniformly arranged to obtain the target color circle, and the target color circle can include 128 different colors. For example, fig. 2 is a schematic diagram of a color wheel in an embodiment of the present application. As shown in fig. 2, the colors in the color ring are uniformly arranged annularly. The color in each cell in the color wheel in fig. 2 may be a different color obtained by difference.
In this embodiment, the attribute value of the reference color includes three color component values. The interpolation process can be performed using the following equation:
wherein c1 and c2 represent a first reference color and a second reference color of two adjacent reference colors in the initial color ring; rc1And Rc2A first color component value representing said first reference color and said second reference color, respectively; gc1And Gc2A second color component value representing said first reference color and said second reference color, respectively; b isc1And Bc2A third color component value representing a first reference color and said second reference color, respectively; cn represents the number of a plurality of discrete attribute values obtained after interpolation processing is performed on the basis of the first reference color and the second reference color; rci、GciAnd BciThe first color component value, the second color component value, and the third color component value in the ith attribute value among the plurality of discrete attribute values obtained by interpolation processing based on the first reference color and the second reference color, respectively.
Step S102: determining a plurality of target colors from the target color ring, and using a set formed by the plurality of target colors as a target color set, so that the attribute difference degree between a target color in the target color set and a reference color in the reference color set is greater than or equal to a preset difference degree threshold value, and the attribute difference degree between two target colors in the target color set is greater than or equal to the preset difference degree threshold value; the type of the color in the target color set is greater than or equal to a second preset color type; the attribute difference degree is determined according to the attribute values of the two colors.
In this embodiment, a plurality of target colors may be determined from the target color ring, and a set of the plurality of target colors may be used as a target color set, such that a degree of attribute difference between a target color in the target color set and a reference color in the reference color set is greater than or equal to a preset degree of difference threshold, and a degree of attribute difference between two target colors in the target color set is greater than or equal to the preset degree of difference threshold; and the type of the color in the target color set is greater than or equal to a second preset color type. Specifically, the following steps may be included.
Step S21: determining a first color and a color position of the first color from the color circle, determining a first attribute difference degree between the first color and a reference color in the reference color set, and judging whether the first attribute difference degree is greater than or equal to a preset difference degree threshold value; and if the color is larger than or equal to the target color set, taking the set formed by the first colors as the target color set.
In this embodiment, the first color may be randomly determined from the color ring by a method of monte carlo simulation. For example, as shown in fig. 3, the color at color position a is randomly chosen as the first color in the color wheel in fig. 2. A first attribute difference between the first color and each reference color in the reference color set can be calculated, and whether the first attribute difference is greater than or equal to a preset difference threshold value can be judged; if the color is greater than or equal to the target color set, the set of the first colors may be used as the target color set. Thus, the target color set includes the corresponding color at color position A in FIG. 3. If the difference is smaller than the preset difference threshold, the first color can be determined from the color ring at random again until the obtained difference of the first attribute is larger than or equal to the preset difference threshold. The value range of the preset difference threshold value can include 25-40. The value of the preset difference threshold may be specifically set according to a display condition of a view in the actual geophysical prospecting software, and is not limited here.
Step S22: determining a second color from the color ring according to the color position of the first color; wherein a color position of the second color is different from a color position of the first color.
In this embodiment, determining the second color from the color ring according to the color position of the first color may specifically include determining three initial colors from the color ring respectively according to the color position of the first color; and sequentially connecting the color position of the first color and the color positions of the initial colors to obtain a square with the center same as the color circle. The initial color may be the second color. For example, as shown in fig. 3, in the color wheel in fig. 2, the color corresponding to the color position B opposite to the color position a may be first used as an initial color, then a straight line passing through the center of the color wheel and perpendicular to the line connecting the color positions a and B may be drawn, the intersection points of the straight line and the color wheel are color positions C and D, respectively, and the colors corresponding to the color positions C and D, respectively, are used as the other two initial colors. At this point, color positions A, B, C and D are connected in sequence, resulting in a square ABCD with the same center as the color circle. Thus, any one of the colors corresponding to color locations B, C and D, respectively, may be used as the second color as a preselected color in the subsequent determination of the color scheme.
In this embodiment, the square may be rotated by a predetermined angle around the center of the color wheel, so as to obtain a rotated square. And in the color ring, the color corresponding to the four vertexes of the rotated square is taken as the second color. The specified angle may be set according to actual conditions, or may be set randomly by a monte carlo simulation method. For example, as shown in fig. 4, the specified angle is 45 degrees, the square ABCD in fig. 3 may be rotated clockwise by 45 degrees to obtain a rotated square, i.e., the square a 'B' C 'D' in fig. 4, so that any one of the colors respectively corresponding to the four vertices in the square a 'B' C 'D' may be used as the second color to be used as the preselected color in the subsequent determination of the color scheme.
Step S23: determining a second attribute difference degree between the second color and a reference color in the reference color set and a third attribute difference degree between the second color and a target color in the target color set, and judging whether the second attribute difference degree and the third attribute difference degree are both greater than or equal to the preset difference degree threshold value; and if the color values are larger than or equal to the target color set, adding the second color into the target color set to obtain a new target color set.
In this embodiment, a second attribute difference between the second color and a reference color in the reference color set and a third attribute difference between the second color and a target color in the target color set may be determined, and it may be determined whether both the second attribute difference and the third attribute difference are greater than or equal to the preset difference threshold; and if the color values are larger than or equal to the target color set, adding the second color into the target color set to obtain a new target color set. For example, in a case that the target color set includes the color corresponding to the color position a in fig. 3, after obtaining the colors corresponding to the color positions B, C and D, the color corresponding to the color position B may be first used as the second color, and if the second attribute difference between the color corresponding to the color position B and each reference color in the reference color set is greater than or equal to the preset difference threshold and the third attribute difference between the color corresponding to the target color set, that is, the color position a, is greater than or equal to the preset difference threshold, the color corresponding to the color position B may be added to the target color set to obtain a new target color set. In this way, the new target color set may include the corresponding colors at color positions A and B, respectively. And if the color corresponding to the color position B does not meet the conditions, taking the color corresponding to the color position C as the second color, and sequentially judging until the selected color is taken as the second color, so that the conditions can be met.
Step S24: and repeatedly determining a new second color from the color ring, determining a new second attribute difference between the new second color and a reference color in the reference color set, determining a new third attribute difference between the new second color and a target color in the new target color set, judging whether the new second attribute difference and the new third attribute difference are both greater than or equal to the preset difference threshold value, and if so, adding the new second color into the new target color set until the type of the color in the new target color set is greater than or equal to a second preset color type.
In this embodiment, the determining of the new second color from the color ring, the determining of the new second attribute difference between the new second color and the reference color in the reference color set, and the determining of the new third attribute difference between the new second color and the target color in the new target color set may be repeated, and whether the new second attribute difference and the new third attribute difference are both greater than or equal to the preset difference threshold value is determined, and if both are greater than or equal to the preset difference threshold value, the new second color is added to the new target color set until the type of the color in the new target color set is greater than or equal to the second preset color type. For example, in a case that the new target color set includes colors respectively corresponding to color positions a and B in fig. 3, the color corresponding to color position C may be continuously used as the new second color, and a new second attribute difference between the new second color and each of the reference colors in the reference color set and a new third attribute difference between the new second color and each of the target colors in the new target color set, that is, a new third attribute difference between the color respectively corresponding to color position a and the color position B. And if the new second attribute difference degree and the new third attribute difference degree are both greater than or equal to the preset difference degree threshold value, adding the new second color into the new target color set until the type of the color in the new target color set is greater than or equal to a second preset color type.
Similarly, the square may be rotated by a predetermined angle around the center of the color wheel, so as to obtain a rotated square. And in the color ring, taking the color corresponding to the four vertexes of the rotated square as the new second color. For example, as shown in fig. 4, the specified angle is 45 degrees, and the square ABCD in fig. 3 may be rotated clockwise by 45 degrees to obtain a rotated square, that is, the square a 'B' C 'D' in fig. 4, so that any one of the colors corresponding to the four vertices of the square a 'B' C 'D' may be used as the new second color. In this way, after the color corresponding to the color position A, B, C, D is screened, any one of the colors corresponding to the four vertices of the square a 'B' C 'D' may be used as the new second color, and the screening may be continued.
In this embodiment, the second predetermined color type is smaller than the first predetermined color type. Specifically, the second preset color category is determined according to the category of the data type displayed by the view in the actual geophysical prospecting software. For example, if there are 6 types of data displayed in the view in the actual geophysical prospecting software, the second predetermined color category is 6 types.
In this embodiment, the attribute difference between the target color in the target color set and the reference color in the reference color set may be determined according to the following formula:
DF＝ΔR2+ΔG2+ΔB2
ΔR＝|Rk-Rm|
ΔG＝|Gk-Gm|
ΔB＝|Bk-Bm|
wherein DF represents a degree of attribute dissimilarity between a kth target color in the set of target colors and an mth reference color in the set of reference colors; rkAnd RmA first color component value representing a kth target color in the set of target colors and an mth reference color in the set of reference colors, respectively; gkAnd GmRespectively representing a k-th target color in the set of target colors and an m-th target color in the set of reference colorsA second color component value of the reference color; bkAnd BmA third color component value representing a kth target color in the set of target colors and an mth reference color in the set of reference colors, respectively.
In this embodiment, the attribute difference between two target colors in the target color set may be determined according to the following formula:
DF＝ΔR2+ΔG2+ΔB2
ΔR＝|Ri-Rj|
ΔG＝|Gi-Gj|
ΔB＝|Bi-Bj|
wherein DF represents the attribute difference degree between the ith target color and the jth target color in the target color set; r isiAnd RjA first color component value representing an ith object color and a jth object color, respectively, of the set of object colors; giAnd GjA second color component value representing an ith object color and a jth object color, respectively, of the set of object colors; b isiAnd BjA third color component value representing an ith object color and a jth object color, respectively, of the set of object colors.
Similarly, the attribute difference between any two colors can be determined according to the above formula.
Step S103: and taking the color combination formed by the target colors in the target color set as a target color matching scheme.
In the present embodiment, a color combination of the target colors in the target color set may be used as the target color scheme. Specifically, when the color type in the target color set is equal to the second preset color type, the color combination formed by the target color set may be used as the target color scheme. When the color type in the target color set is greater than the second preset color type, a color combination formed by the target colors of the second preset color type in the target color set may be used as the target color scheme.
In the method for determining color schemes, first, a target color circle may be generated based on the reference color; the color ring comprises colors of a first preset color type; the colors in the color ring correspond to the color positions one by one; then, a plurality of target colors can be determined from the target color ring, and a set of the plurality of target colors is used as a target color set, so that the attribute difference degree between a target color in the target color set and a reference color in the reference color set is greater than or equal to a preset difference degree threshold value, and the attribute difference degree between two target colors in the target color set is greater than or equal to the preset difference degree threshold value; the type of the color in the target color set is greater than or equal to a second preset color type; the attribute difference degree is determined according to the attribute values of the two colors; finally, the color combinations made up of the target colors in the target color set may be used as the target color scheme. Therefore, a group of strong-contrast color schemes suitable for geophysical prospecting software display can be provided by the method, different types of data in the view can be highlighted, and accordingly harmony and attractiveness of geophysical prospecting software window display are improved.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to the software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abel (advanced boot Expression Language), ahdl (alternate Language Description Language), communication, CUPL (computer universal Programming Language), HDCal (Java Hardware Description Language), langa, Lola, mylar, HDL, PALASM, rhyddl (software Description Language), vhjhdh (Hardware Description Language), vhul, vhal, vhigh, vhygl, vhyg, and vhyg-2. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The apparatuses and modules illustrated in the above embodiments may be specifically implemented by a computer chip or an entity, or implemented by a product with certain functions.
For convenience of description, the above devices are described as being divided into various modules by functions, and are described separately. Of course, the functionality of the various modules may be implemented in the same one or more software and/or hardware implementations as the present application.

With this understanding in mind, the present solution, or portions thereof that contribute to the prior art, may be embodied in the form of a software product, which in a typical configuration includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory. The computer software product may include instructions for causing a computing device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in the various embodiments or portions of embodiments of the present application. The computer software product may be stored in a memory, which may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, computer readable media does not include transitory computer readable media (transient media), such as modulated data signals and carrier waves.
All the embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the apparatus embodiment, since it is substantially similar to the method embodiment, the description is relatively simple, and reference may be made to the partial description of the method embodiment for relevant points.

For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
