Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of embodiments of the present disclosure, as generally described and illustrated herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.

It is found through research that in order to facilitate highlighting each position area during the drawing process of the electronic map, mask pictures corresponding to each area are generally generated in advance, and then each position area is highlighted based on each mask picture.

The mask picture is generated in advance, so that the workload in the map drawing process is greatly increased, and when the position area in the map is changed, the corresponding mask picture needs to be generated again, so that the method has the disadvantages of complicated operation process and low efficiency.

Based on the research, the present disclosure provides a region selection method, a map division method, a device, and a computer device, which respond to a first trigger operation for a target map and determine a color space value of a pixel point corresponding to the first trigger operation; analyzing the color space value to obtain a target position area identifier, and thus, storing the position area identifier by using the color space to effectively solve the storage problem of the position area identifier; and searching target pixel points with the same position area identification as the target position area identification in the target map, and rendering the target pixel points according to a first target display state. Based on the mode, when the area range of any position area changes, only the position area identification corresponding to the position area needs to be changed, compared with the mode of regenerating the mask picture, the method simplifies the operation process and improves the image display efficiency when the area range changes.

The above-mentioned drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to the above-mentioned problems should be the contribution of the inventor in the process of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

To facilitate understanding of the present embodiment, first, a detailed description is given of a region selection method disclosed in an embodiment of the present disclosure, where an execution subject of the region selection method provided in the embodiment of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the region selection method may be implemented by way of a processor calling computer readable instructions stored in a memory.

Referring to fig. 1, a flowchart of a region selection method provided in an embodiment of the present disclosure is shown, where the method includes S101 to S103, where:

s101: responding to a first trigger operation aiming at a target map, and determining a color space value of a pixel point corresponding to the first trigger operation.

S102: and analyzing the color space value to obtain a target position area identifier.

S103: and searching target pixel points with the same position area identification as the target position area identification in the target map, and rendering the target pixel points according to a first target display state, wherein a position area formed by the target pixel points is a target position area corresponding to the first trigger operation.

The following is a detailed description of the above steps:

with respect to S101,

Here, the target map may be an electronic map that has been divided, such as a game map within an electronic game, an electronic map that is applicable to navigation, or the like; the first trigger operation may include any one of click, long press, re-press, single click, and double hit. When the target map is opened, the user can see the target map displayed on the user side, and when the user wants to know the range contained in different position areas, the first trigger operation can be executed on the position area which the user wants to know.

In a possible implementation manner, as shown in fig. 2, the color space value of the pixel point corresponding to the first trigger operation may be determined through the following steps:

s201: and determining screen coordinates corresponding to the first trigger operation, and determining viewpoint information corresponding to the target map when a user executes the first trigger operation.

Through touch detection, screen coordinates corresponding to the first trigger operation can be determined; the viewpoint information corresponding to the target map represents the current view angle of the user viewing the target map, and can be represented by the camera view angle when the target map is displayed, and the camera view angle can be directly read from the display data of the target map.

S202: and determining a three-dimensional coordinate corresponding to the first trigger operation in a three-dimensional model corresponding to the target map based on the screen coordinate and the viewpoint information.

Here, after obtaining the screen coordinates, the screen coordinates corresponding to the first trigger operation may be converted into three-dimensional space coordinates corresponding to the target map through the viewpoint information and a 3D pickup technique.

Specifically, after the screen coordinates are obtained, the screen coordinates may be converted to coordinates in a three-dimensional space in which a map is located by a projection matrix and an observation matrix obtained based on the viewpoint information.

S203: and converting the three-dimensional coordinates into image coordinates on the target map based on the conversion relation between the target map and the three-dimensional model, and acquiring the color space value of a pixel point corresponding to the image coordinates.

Here, after the three-dimensional coordinates are determined, UV coordinates (image coordinates) of the target map corresponding to the first trigger operation may be determined based on the three-dimensional space coordinates.

In one possible embodiment, the coordinates of the three-dimensional space can be transformed into the UV coordinate (image coordinates) space by a straight-line and polygon intersection algorithm.

Illustratively, the coordinates of the lower left corner of the target map correspond to a point (0,0) in the UV coordinate space, the upper right corner corresponds to a point (1,1) in the UV coordinate space, the spatial coordinates and the UV coordinates of the point on the target map are linear correspondences, and based on the linear correspondences, the coordinates of the point corresponding to the first trigger operation in the three-dimensional space can be converted into two-dimensional coordinates on the target map.

Specifically, the conversion may be performed according to the following formula:

wherein in the formula, u represents an abscissa in the UV coordinates; v represents the ordinate in the UV coordinate; x represents the abscissa of a point corresponding to the first trigger operation in the three-dimensional space coordinate; y represents a vertical coordinate of a point corresponding to the first trigger operation in the three-dimensional space coordinate; x is the number of ₀ An abscissa representing a lower left corner of the target map in three-dimensional space; y is ₀ A vertical coordinate in three-dimensional space representing the lower left corner of the target map; the width is the width of the three-dimensional space corresponding to the target map; height is the height of the three-dimensional space corresponding to the target map, wherein the width of the three-dimensional space corresponding to the target map and the height of the three-dimensional space corresponding to the target map are preset.

Further, after the three-dimensional coordinates are converted into image coordinates on the target map, color space values of pixel points corresponding to the image coordinates can be determined; wherein the color space may be an RGBA color space.

For S102 and S103,

Here, the color space may be an RGBA color space, the target map is a color map (that is, the corresponding color space is an RGBA color space), the color map includes R, G, B, A four channels, which respectively represent color spaces of Red (Red), green (Green), blue (Blue), and Alpha, and the image colors of the map to be divided can be represented by using the Red (Red), green (Green), and Blue (Blue) channels.

The Alpha channel is a channel specifically designed to hold a selected region. In computer graphics, a color picture of an RGB color model is composed of three color information channels Red (Red), green (Green), and Blue (Blue), each channel uses 8 bits of color depth, and 24 bits in total, and contains all color information. In order to realize the transparency effect of the graph, another 8-bit information is added in the processing and storage of the graph file, and the added channel information representing the transparency of each prime point in the graph is called an Alpha channel. The Alpha channel uses 8-bit binary numbers to represent 256 levels of gray scale, i.e., 256 levels of transparency. Because the target map does not need to be transparently displayed or non-transparently displayed, the position area identifier corresponding to each pixel point can be stored in the Alpha channel of each pixel point.

Because Alpha channels have limited information that can be stored, when the target map contains more location areas, the mask picture can be used to store location area identification. The pixel points in the mask picture and the pixel points of the target map can be in one-to-one correspondence. Illustratively, a position region identifier 1 may be added to each pixel point in the region 1, and a position region identifier 2 may be added to each pixel point in the region 2. Here, different colors may also be used to represent different regions, where the different colors correspond to different location area identifiers, and pixel points in the same region have the same location area identifier. Such as blue for region 1 and yellow for region 2.

In specific implementation, the number of channels of the mask picture may be selected/adjusted based on parameter information such as the number of regions to be divided, and may be a single channel, a dual channel, a triple channel, or a quadruple channel. Wherein, each channel can store 256 position area identifications in total from 0 to 255.

Illustratively, the mask picture may be as shown in fig. 3. In fig. 3, the mask picture divides the map into three areas by adding

location area identifications

1, 2, 3.

To sum up, the location area identifier may be stored in the Alpha channel and/or the mask picture, and correspondingly, when the target location area identifier is obtained, any one of the following three ways may be used:

mode 1, location area identification is stored only in Alpha channels.

In this case, the color space value may be analyzed, and the value of the Alpha channel in the analysis result may be used as the target location area identifier.

Specifically, the Alpha channel uses 8-bit binary number, which can represent 256-level gray scale, so that the Alpha channel can store 256 target location area identifications at most, and thus the method is suitable for the case that the number of the location area identifications does not exceed 256.

Correspondingly, when searching for target pixel points with the same position area identification as the target position area identification in the target map, the color space corresponding to each pixel point can be directly analyzed, and the value of the corresponding Alpha channel in the analysis result and the pixel points of the target position area identification are determined as the target pixel points.

Mode 2, the location area identification is stored only in the mask picture.

In this case, the color space value may be analyzed, and a mask picture corresponding to the target map is obtained when it is detected that the value of the Alpha channel of the color space is a second preset value based on the analysis result; and determining the value of the pixel point corresponding to the first trigger operation on the channel of the mask picture as the target position area identifier.

Here, since the Alpha channel itself has limited storage capacity, the location area identification can be stored only by a mask picture.

Specifically, the pixel points of the mask picture correspond to the pixel points of the target map one to one, so that the pixel points of the mask picture corresponding to the first trigger operation can be determined, the determined pixel points can be subjected to value taking on the channel of the mask picture, and the target position area identifier corresponding to the first trigger operation can be determined according to the value taking.

Illustratively, taking the second preset value as 0 as an example, when it is detected that the value of an Alpha channel in the analysis result of the color space is 0, a mask picture corresponding to the target map is obtained, and if the value of a pixel point corresponding to the first trigger operation on the channel of the mask picture is 4, the target position area identifier is 4.

Correspondingly, when searching for a target pixel point with a position area identifier identical to the target position area identifier in the target map, the value of the mask picture on the channel can be taken as the pixel point of the target position area identifier, and the corresponding pixel point on the target map is taken as the target pixel point.

Mode 3, location area identification is stored in Alpha channel and mask picture.

In this case, the color space values and the mask picture may be parsed; and then determining the position area identifier corresponding to each pixel point based on the Alpha channel of the target map and the value of at least one channel of the mask picture.

Here, the first preset value may be 256, that is, when the number of location areas in the target map exceeds 256, theoretically, the corresponding location area identifier cannot be completely stored by using an Alpha channel, and therefore, a mask picture corresponding to the target map needs to be acquired.

Specifically, more than 256 parts of the position area identifiers may be stored in the mask picture; alternatively, the position region identifier may be represented in 2-ary form by using a channel of the mask picture and an Alpha channel.

For example, taking the mask picture as a single channel 8-bit (which can represent 256 numbers of the 8 th power of 2), and the Alpha channel is also 8-bit (which can represent 256 numbers of the 8 th power of 2), the channel value in the mask picture can be taken as the high bit in the binary number, the Alpha channel value can be taken as the low bit in the binary number, when the value of the mask picture is represented by binary 00000001, and the value of the Alpha channel is represented by binary 10101011, the concatenated value is 0000000110101011, and the corresponding decimal is 427, the target position area identifier is 427.

Correspondingly, when target pixel points with the same position area identification as the target position area identification in the target map are searched, under the condition that the number of the position areas in the target map exceeds a first preset value, a mask picture corresponding to the target map is obtained; and determining a position area identifier corresponding to each pixel point based on the value of the Alpha channel of the target map and the value of at least one channel of the mask picture, and taking the pixel point with the target position area identifier in the target map as the target pixel point.

Specifically, when the target pixel point is rendered according to the first target display state, at least one of the following methods may be used:

the method 1 displays the target pixel points according to the target display color.

Here, the target display color may be a preset color such as light yellow, light red, or the like; or, the display color may be calculated according to the pixel point corresponding to the first trigger operation and a preset formula.

And 2, changing the display brightness of the target pixel point.

Here, changing the presentation brightness may be increasing/decreasing the presentation brightness of the target pixel point.

And 3, adding the selected pattern on the target pixel point.

Here, the selected pattern may be a pattern that enables the target pixel point to have a highlight effect.

Hereinafter, the method 1 will be described in detail, and the

methods

2 and 3 will not be described.

In specific implementation, when the target pixel point is displayed according to the target display color, new rendering parameters (including values of the pixel point on each color channel) of the pixel point in the target position region are set first after the first trigger operation based on a map rendering tool; and then in the next picture frame, rendering the pixel points corresponding to the target position area according to the new rendering parameters. And rendering the pixel points in other areas except the target position area according to the original rendering parameters.

In a possible implementation manner, the target value of each pixel point in the target position area in the next frame of picture frame on the R, G, B channel can be determined in advance, and then the target position area is rendered based on the target value of each pixel point in the target position area on the R, G, B channel.

When determining the target value of each pixel point in the target position area on the R, G, B channel, for any pixel point, the following formula can be exemplarily referred to for calculation:

R＝r*(1-A)+r*A

G＝g*(1-A)+g*A

B＝b*(1-A)+b*A

r, G, B refers to a target value of each pixel point on a R, G, B channel; a refers to the Alpha value; r, g and b refer to original values of all pixel points on a R, G, B channel.

Illustratively, the resulting presentation effect may be as described in fig. 4. In fig. 4, the target position area changes the display color.

In a possible implementation manner, after the target location area identifier is obtained, edge pixel points corresponding to the target location area identifier may also be determined, and the edge pixel points are rendered according to a second target display state.

Here, the edge pixel points are pixel points located at the edge of the target area, and when the edge pixel points are rendered according to the second target display state, the edge pixel points can be rendered by using a striking color. Illustratively, after the target position area identifier is acquired as an area 1, each edge pixel point of the area 1 may be rendered by using a striking color such as yellow in a unified manner.

Specifically, when determining edge pixel points of edges of each region, an image edge detection algorithm may be used to detect edges of different regions, where the image edge detection algorithm includes a Canny algorithm, a Sobel algorithm, a Laplace algorithm, and the like.

In a possible implementation manner, after the target pixel point in the target location area is rendered according to the first target display state, the display of the target pixel point in the target location area in the first target display state may be cancelled in response to a second trigger operation for the target location area after the display state is changed.

Here, the second trigger operation may include any one of the following operations:

click, long press, re-press, single click, double click.

Specifically, the target pixel point is canceled from being displayed according to the target display color; or, canceling to change the display brightness of the target pixel point; or, the selected pattern is not added to the target pixel point.

Referring to fig. 5, a flowchart of a map division method provided in the embodiment of the present disclosure is shown, where the method includes S501 to S502, where:

s501: obtaining a map to be divided, and determining a position area identifier corresponding to each pixel point in the map to be divided.

S502: and storing the position area identification in the color space of the map to be divided, so that after any pixel point is triggered, based on the position area identification stored in the color space, the pixel point with the same target position area identification as the triggered pixel point is highlighted.

The following is a detailed description of the above steps:

for S501,

Here, when determining a location area identifier corresponding to each pixel point in the map to be divided, area boundary information corresponding to the map to be divided may be obtained first; and then determining a position area identifier corresponding to each pixel point in the map to be divided based on the area boundary information.

Wherein the region boundary information may be region boundary coordinate point data.

Specifically, in a two-dimensional plane, three region boundary coordinate points which are not on the same straight line are sequentially connected, so that a region can be obtained. On the basis, with the increase of the number of the region boundary coordinate points, a more complex and fine geometric figure can be obtained, so that accurate region division information corresponding to each pixel point can be obtained by using enough region boundary coordinate points, for example, four region boundary coordinate points of (0,1), (2,4), (6,8) and (7,0) "are used to obtain a well-divided quadrilateral region.

Illustratively, the quadrilateral area may be as shown in fig. 6. In fig. 6, the four region boundary coordinate points "(0,1), (2,4), (6,8), and (7,0)" are sequentially connected to each other, and then a single quadrangular region is defined in a plane.

After the area boundary information is obtained, it may be determined that all pixel points within the area boundary are divided into the same area based on the area boundary information, so as to determine a location area identifier corresponding to each pixel point in the map to be divided.

For S502,

Here, the color space may be a color space such as an RGBA color space, and when the color space is the RGBA color space, specific contents when the position region identifier is stored may refer to the above related description, which is not described herein again, and after the position region identifier is stored in the color space of the map to be divided, the target map after the map to be divided is divided can be obtained.
