[0058] The computing device 100 may be any type of stationary or mobile computing device, including a mobile computer or mobile computing device (e.g., a tablet computer, a personal digital assistant, a laptop computer, a notebook computer, a netbook, etc.), a mobile phone (e.g., a smart phone), a wearable computing device (e.g., a smart watch, smart glasses, etc.), or other types of mobile devices, or a stationary computing device such as a desktop computer or PC. The computing device 100 may also be a mobile or stationary server.

[0059] The processor 120 may execute Figure 2 The steps in the image generation method shown. Figure 2 A flowchart of an image generation method provided according to an embodiment of the present application is shown, which specifically includes the following steps:

[0060] Step 202: Obtain object lines in the initial image.

[0061] The initial image refers to an image containing object information. In practical applications, the initial image can be understood as a planning image of a scene. The initial image is used as a basic image to automatically generate a target image containing an object based on the marking information (planning information) therein. Correspondingly, the object line refers to a line used to mark the object.

[0062] In practical applications, in order to increase some image details, it may be necessary to add some line-type objects such as railings, cliffs, lakeshores, coastlines, cliffs and viaducts to the image. The creation of these objects can be summarized as placing resources on a broken line. Therefore, in order to improve the generation efficiency of such objects, the present application provides an image generation method that can automatically place line-type resources.

[0063] Considering that the initial image, as a basic image, may need to be modified from time to time, in order to improve the modification efficiency and creation efficiency of the initial image, the initial image can be created by visual configuration. In the embodiment of the present application, the initial image is created in the following manner:

[0064] Receive creation instructions submitted based on the configuration list;

[0065] An initial image is created according to the region information and object marking information corresponding to the creation instruction.

[0066] The configuration list refers to a list for configuring information related to regions and objects in the initial image. Correspondingly, the creation instruction refers to an instruction for creating the initial image.

[0067] Specifically, the configuration list may include multiple configurable items, among which the configuration items of the area information may be configured such as the size information such as the image length and width, the cell information (the number of cells, the number of cell rows, the number of cell columns, the size information of the cell), etc. The configuration items of the object marking information may be configured such as: grid merging information, object location information, object function information, object identification information, object style information, object style information, object material information, object priority information, etc., without limitation here.

[0068] In practical applications, the region information is usually used to create the image size and cells in the initial image. The object marking information is used to mark the object to be created in the initial image. Specifically, the marking process can be marked in the image by text, color, wireframe, line, surface, etc., which are not limited here.

[0069] In addition, in order to further improve the configurability of the initial image and the convenience of subsequently generating the target object, the initial image can also be an image containing a grid (i.e., a cell). Such an image containing a grid can also be called an object grid image.

[0070] In summary, by creating the initial image according to the region information and object marking information corresponding to the creation instruction, the initial image is created in a visual configuration manner, thereby improving the efficiency of creating the initial image.

[0071] Step 204: Determine the line type and line component style based on the object line.

[0072] Specifically, based on the object lines in the initial image, considering that different types of lines require different object resources, and these object resources may be placed in different ways, it is necessary to first determine the line type and line component style based on the object lines.

[0073] Among them, the line type can be divided into a closed line type and an open line type according to whether the object line is closed. The line component style refers to the component style matching various line segments in the object line.

[0074] In practical applications, if the object line is a curve or an angle, it is difficult to pre-prepare all possible matching object resources for such object lines. Therefore, in order to simplify the creation of line type objects, the obtained object lines can be pre-processed. In the embodiment of the present application, it is specifically determined in the following manner:

[0075] In the case where there is a curve in the object line, converting the curve into a polyline according to a preset conversion rule;

[0076] In the case where there is an angle in the object line, the angle of the angle is adjusted to a preset angle.

[0077] The preset conversion rule may be to draw a tangent to the curved part of the object line and convert the curved part into a polyline. In addition, the preset conversion rule may be to straighten the curve in the object line and convert the object line into a polyline. When straightening, the straightening may be performed according to a preset reference line, such as according to the grid edge line in the initial image, or according to the center line of the grid in the initial image, etc., without limitation.

[0078] In practical applications, after the object lines are converted from curves to polylines, there are usually angles between the polyline lines. Specifically, the angle may be 24 degrees, 156 degrees, etc. Due to the uncertainty of the angle in the object lines, it is difficult to pre-produce object resources containing all angles. Therefore, the angle can be adjusted to a pre-set angle (i.e., a preset angle) such as 90 degrees or 60 degrees. In specific implementation, the angle can be adjusted to the preset angle by enlarging or reducing the angle.

[0079] For example, the lake shore lines in the initial image are as follows Figure 3 As shown in (a), the lakeshore line is straightened according to the center line of the cell within the cell range to which it belongs in the initial image, so that a convex-shaped broken-line lakeshore line can be obtained. Figure 3 (b) as shown.

[0080] In summary, by converting the curves in the object lines into straight lines and converting the angles in the object lines into preset angles, the standardization of the object lines is ensured and the efficiency of object creation is further improved.

[0081] In specific implementation, the line type is determined in the following manner:

[0082] Determine whether there is a target line point without adjacent points on both sides among the line points of the object line;

[0083] If not, it indicates that the object line does not have an endpoint, and the line type is determined to be a closed line type;

[0084] If so, it indicates that the object line has endpoints, and the line type is determined to be a non-closed line type.

[0085] Among them, the line point refers to the point in the object line. Correspondingly, the adjacent points on both sides refer to the adjacent points arranged before and after the line point in the object line. Among them, the adjacent points refer to the points adjacent to the line point in the line object. In practical applications, if any line point has only one adjacent point on one side, then the line point is the target line point, which also indicates that the line point is the endpoint of the object line. If the object line has an endpoint, it can be determined that the line type of the object line is a non-closed line type.

[0086] If all line points in the object line have adjacent points on both sides, that is, the line points of the object line do not have the target line point, it means that the object line does not have an endpoint. If the object line does not have an endpoint, it can be determined that the line type of the object line is a closed line type.

[0087] Using the above example, Figure 3 The line points in the broken-line lakeshore line in (b) are detected one by one to determine that each line point has adjacent points on both sides. There is no target line point in the line points of the lakeshore line, which also indicates that the lakeshore line has no endpoints. Therefore, it can also be determined that the line type of the lakeshore line is a closed line type.

[0088] In summary, by determining whether there is a target line point without adjacent points on both sides among the line points of the object line, the line type of the object line is determined, thereby ensuring the accuracy of determining the line type.

[0089] Furthermore, the line component style is determined in the following two ways:

[0090] Method 1: segmenting the object line according to a preset segmentation rule to obtain at least one line segment;

[0091] The line segment is matched with a preset line component style to determine the line component style corresponding to the object line.

[0092] The preset segmentation rule may be to segment the object line into sub-segments according to the cells in the initial image, that is, to segment the object line that belongs to one or more cells as line segments. In addition, the object line may be segmented into line segments according to preset line segment lengths (such as 5 meters, 1 meter, etc.), which is not limited here.

[0093] The preset line component style refers to a component style pre-set for the object line. In specific implementation, the line segment is matched with the preset line component style, which can be matched by calculating the similarity between the two using a pre-trained similarity model. In the case of multiple line segments, each line segment is matched with the preset line component style in turn. Furthermore, the preset line components with the same or similar matching results are determined as the line component style corresponding to the line segment. And the line component styles corresponding to all line segments in the object line are used as the line component style corresponding to the object line.

[0094] Using the above example, Figure 3 The lakeshore lines in (b) are segmented according to the cells in the initial image to obtain 10 line segments. Each line segment is matched with a preset line component style to obtain the preset line component style corresponding to each line segment, i.e., the line component style.

[0095] Method 2: Calculate preset line points on the object line to determine the type of target line points included in the object line;

[0096] A line component style is determined based on the type and the object line.

[0097] Specifically, the calculation of preset line points (such as intersections, corner points, and endpoints) of the object line can be understood as calculating the line points of intersections, corner points, and endpoints formed in the object line, and taking the preset line points in the object line as target line points. Then, according to the type of the target line point, the special positions in the object line (such as cross intersections, T-intersections, corners, and ends) are determined, and the styles formed by these special positions are used as line component styles. In addition, the straight line positions in the object line other than these special positions can correspond to the straight line component style, and the straight line component style is also used as the line component style.

[0098] In specific implementation, the object line can be divided into at least one straight line segment, and then calculate whether the endpoints of these straight line segments overlap; if the endpoints of four straight line segments overlap, the overlapped endpoints are determined to be cross intersections; if the endpoints of three straight line segments overlap, the overlapped endpoints are determined to be T-intersections; if the endpoints of two straight line segments overlap, the overlapped endpoints are determined to be corner points; if a straight line segment has endpoints that do not overlap, the endpoint is determined to be the endpoint of the object line. Then, according to the types (such as cross intersections, T-intersections, corner points, endpoints, etc.) of these target line points (such as cross intersections, T-intersections, corner points, endpoints, etc.), the corresponding line style components (such as cross intersection component style, T-intersection component style, corner component style, endpoint component style, etc.) are determined.

[0099] In addition, for the non-endpoint part of the object line, the corresponding line style component is determined to be a straight line component style. The endpoint part can be understood as a line segment including the endpoint, and the length of the line segment can be determined according to the preset component size (for example, the endpoint is a cross type, and the preset length corresponding to the cross type is 5 meters. The endpoint is used as the center point, and the four line segments belonging to the center point are cut by 5 meters respectively as the endpoint part). In addition, it is also determined according to the size of the cell in the initial image (for example, the endpoint and line segment belonging to the same cell are regarded as the endpoint part), which is not limited here.

[0100] Using the above example, Figure 3 The lakeshore line in (b) is divided into 8 straight line segments, and it is determined that the endpoints of the 8 straight line segments overlap, and the number of overlaps of the overlapped endpoints is 2. According to the number of overlaps 2, it can be determined that the type of the target line point is a corner type. According to the corner type, it can be determined that the line component style corresponding to the corner type is a corner component style. Then, according to the cell to which the target line point belongs in the initial image, the line segment part (i.e., the endpoint part) corresponding to the corner component style is separated from the object line. The line component style corresponding to the straight line part of the object line except the endpoint part is determined as the straight line component style.

[0101] In summary, by determining the line component style corresponding to the object line in the above two ways, the diversity and flexibility of determining the line component style are increased.

[0102] Step 206: Determine the object resource corresponding to the object line according to the line component style, and determine the location information of the object resource according to the object line and the line type.

[0103] Specifically, based on the above determination of the object type and line component style of the object line, it is necessary to determine the object resource and position information corresponding to the object line based on this information, so as to place the object resource according to the position information.

[0104] Among them, object resources refer to resources such as models, prefabricated parts, and maps corresponding to object lines. The object resources can be two-dimensional or three-dimensional, without limitation. Correspondingly, position information refers to information about the location where the object resource is placed in the initial image. Specifically, the position information can be coordinate information, position reference (such as cell) information, direction information, etc., without limitation.

[0105] In a specific implementation, the determining of the object resource corresponding to the object line according to the line component style is specifically implemented in the following manner:

[0106] Determine a resource library corresponding to the object line;

[0107] An object resource matching the line component style is determined in the resource library according to the attribute information of the line component style.

[0108] A resource library refers to a storage space for storing resources corresponding to object lines. The resource library can be a database, a storage server, or a specific disk, folder, etc., which is not limited here. In practical applications, there are various ways to determine the resource library corresponding to an object line. Specifically, object lines of different object types usually correspond to different resource libraries. For example, lakeshore lines correspond to lakeshore resource libraries, viaduct lines correspond to viaduct resource libraries, and river lines correspond to river resource libraries. During specific implementation, the correspondence between object type and resource library information (such as resource library path, resource library identification, etc.) can be pre-set, and the corresponding resource library can be determined based on the object line. In addition, the object type of the object line can also be used as part of the identification information of the line component style. In this case, the resource library matching the object type information can also be determined based on the object type information in the identification information of the line component style.

[0109] Furthermore, based on the attribute information of the line component style (such as style information, name information, inner and outer angle information and / or size information), etc., a resource search is performed in the resource library to determine the object resource matching the line component style.

[0110] In specific implementation, the attribute information of the line component style can be compared with the attribute information of the resources in the resource library, so as to select the object resources with matching attribute information in the resource library as the object resources matching the line component style. In addition, the resources in the resource library can be named according to the resource attributes using a unified naming rule, such as the naming rule: type_style_size. Then, the object type, style, size and other information of the line component style are compared one by one with the resource attributes in the resource naming, filtered layer by layer, and finally the resources that meet the requirements are selected as the object resources matching the line component style.

[0111] It should be noted that for closed object lines, the corresponding angles of the line component style in the object line may be divided into inner angles and outer angles. Among them, the outer angle refers to the angle whose angle facing the center point of the object line is greater than 180 degrees; the inner angle refers to the angle whose angle facing the center point of the object line is less than 180 degrees. Since the appearance of the inner and outer sides of object resources such as lakeshores and coastlines may be different (for example, seaweed and other decorations may be added to the inside of the resource when making object resources). Therefore, when describing object resources, it is usually necessary to make different object resources according to the difference between inner angles and outer angles. And add marks for inner and outer angles to distinguish them.

[0112] Therefore, when the line type of the object line is a closed line type, it is necessary to determine the object resource of the inner angle or outer angle that matches the line component style according to the label of the inner angle or outer angle of the line component style. In specific implementation, an inscribed circle and an circumscribed circle can be drawn for the object line. If the angle corresponding to the line component style in the object line is an angle toward the circumscribed circle, then the angle is an outer angle. Figure 3 The two angles shown in (c) are both external angles; if the corresponding angle of the line component style in the object line is an angle toward the inscribed circle, then the angle is an internal angle. Figure 3 The six angles shown in (c) are all inner angles. After distinguishing the inner and outer angles, add an inner angle or outer angle label to the line component style. The label information is also used as the attribute information of the line component style. Based on the attribute information, the object resource of the corresponding inner angle or outer angle is matched.

[0113] For example, on the basis of determining that the line component style corresponding to the lakeshore line is the corner component style and the straight line component style, according to the mapping relationship between the pre-set line type and the resource library path, it can be known that the line type of the lakeshore line: the resource library path corresponding to the lakeshore type is P1. The storage space pointed to by the resource library path P1 is determined as the lakeshore resource library corresponding to the lakeshore line. And according to the style name of the corner component style corresponding to the lakeshore line: corner, and the inner and outer angle labels: inner angle, the lakeshore corner model with the inner angle label is screened out from the lakeshore resource library as the lakeshore model corresponding to the corner component style. In addition, according to the style name of the straight line component style corresponding to the lakeshore line: straight line, the lakeshore straight line model is screened out from the lakeshore resource library as the lakeshore model corresponding to the straight line component style.

[0114] In the specific implementation, since the object resource needs to be placed in the correct position on the basis of determining the object resource, the target object can be finally generated. Different types of object lines may have different placement methods. In order to further improve the accuracy and efficiency of resource placement, different placement methods can be adopted for object lines of different line types. Therefore, in the embodiment of the present application, when the line type is a non-closed line type, the position information of the object resource is determined according to the object line and the line type, which is specifically implemented in the following manner:

[0115] Determine a placement reference point of the object resource in a line segment corresponding to the object line according to a preset reference point rule;

[0116] Calculate the offset information between the object resource and the line segment based on the placement reference point and the line segment corresponding to the object resource in the object line;

[0117] The placement reference point and the offset information are used as the position information of the object resource.

[0118] The preset reference point rule refers to a preset rule for selecting a placement reference point. Specifically, the preset reference point rule may be to select the center point of the line segment corresponding to the object resource in the object line as the object reference point. In addition, the preset reference point rule may also be to select the endpoint of the line segment as the placement reference point, etc., which is not limited here.

[0119] It should be noted that there may be multiple line segments in an object line that correspond to the same line component style, so these line segments also correspond to the same object resource. In this case, the placement reference point of the object resource in each line segment corresponding to the object line needs to be determined, so that the object resource can be placed multiple times in the object line based on the placement reference point.

[0120] On the basis of determining the placement reference point, since the placement position of a two-dimensional or three-dimensional object resource in the initial image cannot be determined by placing the reference point, it is also necessary to determine the placement angle of the object resource in order to accurately place the object resource. In specific implementation, based on the placement reference point and the line segment corresponding to the object resource in the object line, the offset information between the object resource and the line segment is calculated, which can be achieved in the following way:

[0121] Determining a reference baseline of the object resource on the line segment according to a preset baseline of the object resource;

[0122] Based on the placement reference point, the preset reference line and the reference reference line, the offset information between the object resource and the line segment is calculated.

[0123] The preset baseline refers to a baseline pre-set for an object resource (i.e., a preset baseline). Specifically, the preset baseline can be the positive axis of the object resource (for example, if the front of the pre-made object resource is vertically downward, the vertically downward coordinate axis can be used as the positive axis of the object resource), the center line of the object resource, the left sideline, or the right sideline; in addition, the preset baseline can also be a line segment between the center point of the object resource and the placement reference point, etc., which is not limited here. Correspondingly, the reference baseline can be understood as the baseline of the object area formed by the line segment corresponding to the object resource. In specific implementation, if the preset baseline is the positive axis of the object resource, the reference baseline is also the positive axis of the object area formed by the line segment; if the preset baseline is the center line of the object resource, the reference baseline is also the center line of the object area formed by the line segment. In short, when the object resource and the object area formed by its corresponding line segment are aligned, the preset reference line should also be completely aligned with the reference baseline.

[0124] Furthermore, after determining the reference baseline of the line segment corresponding to the object resource in the object line, the offset information between the reference baseline and the preset baseline can be determined. In specific implementation, the offset information can be determined by calculating based on the position information of the preset baseline (the position information can be understood as the position information corresponding to the preset baseline in the initial image when the object resource is placed at the placement reference point, that is, when the resource point corresponding to the placement reference point in the object resource is aligned with the placement reference point) and the position information of the reference baseline.

[0125] Specifically, the offset information includes the offset angle between the preset baseline and the reference baseline (such as 90 degrees, 180 degrees, etc.) and the offset direction corresponding to the offset angle (such as left, right, etc.). In actual applications, the pre-created object resources are usually placed in a unified direction. For example, the positive axes of these object resources are placed perpendicular to the screen. This direction may have an offset angle with its actual placement direction. Therefore, it is necessary to determine the offset angle and offset direction of the object resource (such as 180 degrees to the left, or 90 degrees to the right, etc.). So that on the basis of the placement reference point, the placement position of the object resource can be adjusted according to the offset information so that the placement position of the object resource coincides with the actual object position.

[0126] In summary, on the basis of determining the placement reference point and the offset information, the placement reference point and the offset information are used as the position information of the object resource, thereby ensuring the correctness of the placement of the object resource.

[0127] In the case where the line type is a closed line type, determining the location information of the object resource according to the object line and the line type is specifically implemented in the following manner:

[0128] Determine a placement reference point of the object resource in a line segment corresponding to the object line according to a preset reference point rule;

[0129] Calculating the center point of the object line;

[0130] Determine rotation information of the object resource according to the center point and a line segment corresponding to the object resource in the object line;

[0131] The rotation information and the placement reference point are used as the position information.

[0132] Specifically, the method of determining the placement reference point of the object resource in the line segment corresponding to the object line according to the preset reference point rule is similar to the implementation method of determining the placement reference point in the above method embodiment, which is not repeated here.

[0133] Furthermore, since the object line is a closed line type, the center point of the object line can be understood as the center point of the closed area formed by the object line. In specific implementation, the center point of the object line can be calculated by calculating the circumscribed circle corresponding to the object line, and the center point of the circumscribed circle is used as the center point of the object line. In addition, the inscribed circle corresponding to the object line can also be calculated, and the center point of the inscribed circle is used as the center point of the object line, etc., which is not limited here.

[0134] Furthermore, the rotation information of the object resource is determined according to the center point and the line segment corresponding to the object resource in the object line. In specific implementation, the center point of the line segment corresponding to the object resource in the object line can be determined first. And the line segment vector between the center point of the line segment and the center point of the object line is calculated. Then the resource vector between the center point of the object resource and the center point of the object line is calculated. Finally, the rotation direction and rotation angle between the resource vector and the line segment vector are calculated, and the rotation direction and rotation angle are used as the rotation information of the object resource.

[0135] In addition, if the direction of the connection line of the object resource is not fixed, the connection between the object resources may be discontinuous or impossible to connect. For example, object resource 1 and object resource 2 are adjacent, and the direction of the connection line of object resource 1 relative to object resource 2 is 45 degrees upward, while the direction of the connection line of object resource 2 relative to object resource 1 is 0 degrees, then the connection lines of the two cannot overlap. Therefore, in order to simplify the connection between object resources, the rotation angle determined above can also be corrected. Correct the rotation angle to a rotation angle of straight up, straight down, straight left or straight right. Figure 3 As shown in (d), the rotation angle is corrected to a straight-up rotation angle. In this case, the connecting lines between the object resources can also be reduced to two directions: parallel or vertical. The corrected rotation angle and rotation direction are then used as the rotation information of the object resource. The placement reference point and rotation information are used as position information.

[0136] In summary, for closed object lines, the rotation information is determined based on the center point of the object line and the line segment corresponding to the object resource, and the placement reference point and the rotation information are used as the position information of the object resource. This ensures that all object resources are placed toward the inner center point.

[0137] Step 208: updating the initial image based on the object resource and the position information to obtain a target image including the target object corresponding to the object line.

[0138] Specifically, based on the object resource and the location information of the object resource obtained above, the object resource can be automatically placed in the initial image according to the location information, thereby generating a target image containing the target object.

[0139] The image generation method provided by the embodiment of the present application obtains object lines in an initial image; determines line types and line component styles based on the object lines; determines object resources corresponding to the object lines according to the line component styles, and determines location information of the object resources according to the object lines and the line types; updates the initial image based on the object resources and the location information to obtain a target image containing a target object corresponding to the object lines, thereby realizing automatic placement of object resources corresponding to the object lines, improving target image generation efficiency, and reducing labor costs and time costs.

[0147] Step 414: Determine the placement reference point of the lakeshore resource in the corresponding line segment in the lakeshore line according to the preset reference point rule.

[0148] Step 416: Calculate the center point of the lake shore line.

[0149] Step 418: Determine the rotation information of the lakeshore resource according to the center point and the line segment corresponding to the lakeshore resource in the lakeshore line.

[0150] Step 420: Use the rotation information and the placement reference point as the location information of the lakeshore resource.

[0151] Step 422: Update the initial image based on the lakeshore resources and placement information to obtain a target image of the lakeshore object corresponding to the lakeshore line.
