However, with the rapid economic development and rapid urbanization in recent years, the cultural heritage, historical environment and city characteristics in the city have been damaged to some extent. Therefore, at the present stage, actively collecting and mining historical and cultural heritage data and classifying and archiving can provide data support for the scientific management and protective updating of historical and cultural cities in the whole life cycle.

[0003] Historical and cultural cities have a large number of historical and cultural heritage, including historical and cultural blocks, river systems, protected units, controlled and protected buildings, historical buildings, gardens, ancient city walls, famous trees and more than 20 types of protected objects. The historical elements to be collected are rich and diverse, and the information is huge.

[0013] By adopting the above technical solution, first, the to-be-output image pattern is divided through on-site investigation, and the to-be-output image pattern matched with the on-site aerial image map is determined according to the first feature information of the on-site aerial image map.

[0016] The buildings of the same type attribute in the same area are summarized to delineate the to-be-output image pattern.

[0017] By adopting the above technical solution, the type attributes of different buildings are different, the type attributes of the buildings in each to-be-output image pattern are the same, and the buildings in each to-be-output image pattern belong to the same area. The on-site aerial image map is conveniently corrected or the image processing model is conveniently obtained, the standard is unified, and the achievement drawing obtained after processing is more standardized and normative.

[0018] In a specific implementable scheme, the processing of the on-site aerial image map according to the to-be-output image pattern specifically includes the following steps:

[0019] One of the buildings in the to-be-output image pattern is selected as a first reference;

[0020] The position of the first reference in the on-site aerial image map corresponding to the to-be-output image pattern is determined;

[0021] The position of the to-be-output image pattern in the on-site aerial image map is determined according to the position of the first reference;

[0022] The image correction model is preset, and the aerial image is cut according to the position of the to-be-output graph in the aerial image, and the cut aerial image is corrected.

[0023] According to the above technical scheme, the to-be-output graph is divided according to the type attribute of the building in the to-be-output graph, and the size of the aerial image and the shape of the building in the aerial image may have some problems due to the shooting problem when the aerial image is shot. The aerial image is cut and corrected, so that the aerial image and the to-be-output graph can be better corresponded.

[0024] In a specific embodiment, the method further comprises the following steps before the pre-built graph image processing model is obtained:

[0025] The pre-built dynamic link library is obtained, and the dynamic link library pre-stores the graph image processing model corresponding to different type attributes;

[0026] The to-be-output graph is analyzed to determine the type attribute corresponding to the building in the to-be-output graph;

[0027] According to the type attribute corresponding to the building in the to-be-output graph, the graph image processing model corresponding to the to-be-output graph is selected from the dynamic link library.

[0028] According to the above technical scheme, the dynamic link library is constructed, the corresponding graph image processing model is selected according to the type attribute, different output parameters are set for different type attributes, and the actual output result map is more rapid and accurate.

[0029] In a specific embodiment, the output parameter setting step further comprises the following steps:

[0030] According to the type attribute of the to-be-output graph, the graph category is selected;

[0031] According to the type attribute of the to-be-output graph, the corresponding historical setting file is obtained from the pre-built file storage library, and the file storage library stores a plurality of historical setting files, and each historical setting file corresponds to a type attribute;

[0032] The historical parameters are obtained based on the historical setting file.

[0033] According to the above technical scheme, the file storage library is constructed, the corresponding historical setting file is selected according to the type attribute, and the output parameter of the to-be-output graph is set according to the historical parameter of the historical setting file, which is more efficient.

[0034] In a specific embodiment, the output category includes a traditional resident category and a cultural relic building category, and the output result paper specifically includes the following steps:

[0035] According to the type attribute of the to-be-output graph, it is determined whether the to-be-output graph is a traditional resident category or a cultural relic building category.

[0036] If the to-be-output graph is a traditional resident category, the traditional resident category result paper is output based on a preset first output standard.

[0037] If the to-be-output graph is a cultural relic building category, the cultural relic building category result paper is output based on a preset second output standard.

[0038] By using the above technical solution, in order to distinguish between buildings of the traditional resident category and buildings of the cultural relic building category, the result paper is output by different output standards, so that the buildings of the traditional resident category and the buildings of the cultural relic building category can be more intuitively distinguished from the image of the entire historical and cultural city.

[0039] In a specific embodiment, the output result paper further includes the following steps:

[0040] The pre-generated first standard frame, the size of the first standard frame, and the size of the to-be-output graph are obtained.

[0041] The ratio between the size of the first standard frame and the size of the to-be-output graph is calculated to obtain a first ratio.

[0042] According to the first ratio, a magnification ratio is determined from a pre-constructed frame adjustment library, and the frame adjustment library stores a plurality of ratio intervals, and each ratio interval corresponds to a magnification ratio.

[0043] According to the magnification ratio, the size of the first standard frame is magnified to obtain an actual frame.

[0044] The to-be-output graph is output into the actual frame.

[0045] By using the above technical solution, since the sizes of the to-be-output graphs are different, when the size of the to-be-output graph is greater than the size of the first standard frame, the size of the first standard frame needs to be magnified, so that the to-be-output graph can be output into the magnified first standard frame.

[0074] The to-be-output graphics storage module is used for storing a plurality of pre-delineated to-be-output graphics;

[0075] In the embodiment of the present application, the types of buildings in the same to-be-output graphics are the same, and the type attributes include traditional resident group class, traditional resident building monomer class, historical building class, historical building body class, historical courtyard class, historical courtyard body building class, other building class and other building body building class.

[0076] The information acquisition module 2 is used for acquiring the first feature information of the on-site aerial image and the on-site aerial image;

[0077] The first feature information includes the shooting position and the shooting direction, and according to the shooting position and the shooting direction, the on-site aerial image can be adjusted subsequently.

[0078] The information matching module 3 is used for determining the to-be-output graphics corresponding to the on-site aerial image according to the first feature information;

[0079] Specifically, the shooting position and the shooting direction of the on-site aerial image are acquired, and the to-be-output graphics corresponding to the on-site aerial image is determined according to the shooting position and the shooting direction of the on-site aerial image.

[0080] The picture processing module 4 is used for determining the position of the to-be-output graphics in the on-site aerial image, and combining the position of the to-be-output graphics in the on-site aerial image, the on-site aerial image is cut, and the cut on-site aerial image is corrected to obtain a to-be-output image;

[0081] The parameter setting module 5 is configured to acquire a pre-constructed graphic image processing model according to the type attribute of the building in the to-be-output graphic, and set the output parameter through the graphic image processing model.

[0082] The drawing output module 6 is configured to output the result drawing based on the output parameter and in combination with the to-be-output graphic and the to-be-output image graphic.

[0083] With reference to Figure 2 In another embodiment of the present application, a graphic image standardization processing method for a historic and cultural city is provided, comprising the following steps:

[0084] S10, acquiring a plurality of pre-delineated to-be-output graphics;

[0085] In the to-be-output graphics, the type attributes of all the buildings in the same to-be-output graphic are the same, and the type attributes of the buildings in different to-be-output graphics are the same. Figure 3 Specifically, the pre-delineation of the to-be-output graphic comprises the following steps:

[0086] A10, acquiring an original topographic map of the historic and cultural city, and dividing the original topographic map into a plurality of sections;

[0087] In the historic and cultural city, a plurality of buildings with different type attributes are included, the adjacent buildings are divided into the same section, and the buildings in the section all belong to the object buildings, and the determination standard of the object buildings is the determination standard of the historic and cultural city formulated by the state.

[0088] A20, the buildings with the same type attribute in the same section are summarized to delineate the to-be-output graphic.

[0089] In one embodiment of the present application, in order to distinguish the buildings with different type attributes when the on-site aerial image is generated, it is necessary to ensure that the type attributes of the buildings in the same to-be-output graphic are the same.

[0090] S20, acquiring the on-site aerial image and the first feature information of the on-site aerial image, and determining the to-be-output graphic corresponding to the on-site aerial image according to the first feature information;

[0091] S30, correcting the on-site aerial image according to the to-be-output graphic to obtain a to-be-output image graphic;

[0092] In the implementation, the image of the entire historic and cultural city is generated, and the on-site aerial images corresponding to all the to-be-output graphics need to be integrated. Due to the uncertainty of shooting, it is difficult for the actually shot on-site aerial image to completely match the to-be-output graphic, and therefore the on-site aerial image needs to be corrected. Figure 4 Specifically, the correction comprises the following steps:

[0093] B10, selecting one building in the to-be-output graph as a first reference;

[0094] It should be noted that the type attribute of the selected one building in the to-be-output graph is consistent with the type attribute corresponding to the to-be-output graph.

[0095] B20, determining the position of the first reference in the on-site aerial image corresponding to the to-be-output graph;

[0096] In implementation, the target region in the on-site aerial image is determined by comparing the position of the first reference in the to-be-output graph and the position of the first reference in the on-site aerial image. It should be noted that the target region is the region where all buildings in the on-site aerial image have the type attribute consistent with the type attribute corresponding to the to-be-output graph.

[0097] B30, determining the position of the to-be-output graph in the on-site aerial image according to the position of the first reference;

[0098] B40, cutting the on-site aerial image by using a pre-set image correction model and combining the position of the to-be-output graph in the on-site aerial image, and correcting the cut on-site aerial image.

[0099] In the embodiment of the present application, the image correction model is PhotoShop. Since the sizes of the to-be-output graphs are inconsistent, the matching degree of the on-site aerial image and the corresponding to-be-output graph is not necessarily good. Therefore, the position of the to-be-output graph in the on-site aerial image is determined, so that the on-site aerial image is cut by using PhotoShop. In addition, due to the shooting angle, the size and clarity of the buildings in the on-site aerial image may be inconsistent. At this time, the on-site aerial image is corrected by using the deformation software in PhotoShop.

[0100] S40, obtaining a pre-constructed graph image processing model, and setting an output parameter by using the graph image processing model;

[0101] In an embodiment of the present application, in order to realize the standardized output of the historical and cultural city image, different graph image processing models are selected according to the type attributes corresponding to different type attributes of the to-be-output graph, and the graph image processing model is set according to the type attribute of the to-be-output graph.

[0105] C30, select a graph image processing model corresponding to the to-be-output graph from a dynamic link library according to the type attribute corresponding to the building in the to-be-output graph.

[0106] In implementation, each graph processing model corresponds to a set of output parameters, and different output parameters are set to distinguish to-be-output graphs of different type attributes.

[0107] In another embodiment of the present application, the parameters can also be set according to historical data, as described in Figure 6 , and the steps include:

[0108] D10, select a graph category according to the type attribute of the to-be-output graph;

[0109] D20, obtain a corresponding historical setting file from a pre-constructed file storage according to the type attribute of the to-be-output graph;

[0110] The file storage stores a plurality of historical setting files, and each historical setting file corresponds to a type attribute.

[0111] D30, obtain historical parameters based on the historical setting file.

[0112] It should be noted that the historical setting files in the file storage are periodically updated.

[0113] S50, output the result drawing based on the output parameters and in combination with the to-be-output graph and the to-be-output image graph.

[0114] The graph category includes a traditional resident category and a cultural relic building category, the traditional resident category includes traditional residents and other buildings, and the cultural relic building category includes historical elements and historical buildings in cultural relic buildings. After the result drawing is output according to the output parameters, the output result drawing is modified according to the graph category of the to-be-output graph, and the steps include:

[0115] According to the type attribute of the to-be-output graph, it is determined whether the to-be-output graph is a traditional resident category or a cultural relic building category;

[0116] If the to-be-output graph is a traditional resident category, a traditional resident category result drawing is output based on a preset first output standard;

[0117] If the to-be-output graph is a cultural relic building category, a cultural relic building category result drawing is output based on a preset second output standard.

[0118] In an embodiment of the present application, the output result drawing is exported by CAD software, when the to-be-output graph is a traditional resident type, the line color is unified, the building description text is newly added, and the font size is set to 1.2; when the to-be-output graph is a cultural relic building type, the original element expression form and number of the building are retained, and the scale size is set to 0.5.

[0119] In implementation, in order to store the output result drawing into the preset graph frame, the following steps are specifically included: Figure 7

[0120] E10, a pre-generated first standard graph frame, a size of the first standard graph frame, and a size of the to-be-output graph are acquired;

[0121] E20, a ratio between the size of the first standard graph frame and the size of the to-be-output graph is calculated to obtain a first ratio value;

[0122] E30, according to the first ratio value, a magnification ratio is determined from a pre-constructed graph frame adjustment library;

[0123] The graph frame adjustment library stores a plurality of ratio value intervals, and each ratio value interval corresponds to a magnification ratio.

[0124] E40, the size of the first standard graph frame is magnified according to the magnification ratio to obtain an actual graph frame;

[0127] It should be noted that, since the content of the result drawing is limited, the size of the first standard graph library can not be changed according to the magnification ratio, but the effect of outputting the to-be-output graph into the actual graph frame can be achieved by changing the scale in the result drawing.
