[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that the terms "comprises" and "specifically" and any variations of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] See also Figure 1 , Figure 1 1 is a flow chart of a spatial node updating method provided by an embodiment of the present invention, the spatial node updating method comprising:

[0037] S1, obtain the community space node of electronic map data;

[0038] S2, obtaining a spatial enclosure type of each spatial node according to the spatial enclosure degree of the spatial node;

[0039] S3, evaluating each spatial node according to the spatial enclosure type and a preset spatial evaluation index system to obtain a spatial evaluation result of each spatial node;

[0040] S4, updating each spatial node according to the spatial evaluation result and a preset spatial update strategy.

[0041] Exemplarily, the electronic map data (such as elevation image map, satellite map, etc.) of the target area is obtained through GIS, and the community space nodes that need to be updated and renovated are screened out from the electronic map data, and then field visits and surveys are conducted to understand the needs of surrounding residents and users; according to the differences in the degree of enclosure of the surrounding buildings of the spatial nodes, four types of spatial enclosures are divided into single-sided building enclosure type, double-sided building enclosure type, three-sided building enclosure type and four-sided building enclosure type; according to the spatial enclosure type, each spatial node is scored using a preset spatial evaluation index system to obtain the score of each spatial node, and the corresponding spatial update strategy is found from the preset spatial update strategy through the score, and the spatial node is updated through the spatial update strategy. A systematic and replicable spatial node update method is provided, according to the spatial enclosure type and the preset spatial evaluation index system, the scientificity and accuracy of the spatial evaluation results of the spatial node are improved, the spatial node is updated through the preset spatial update strategy, the utilization efficiency of the spatial resources in the target area is improved, the spatial quality of the spatial node is effectively improved, and the living environment of the residents is improved.

[0042] It is worth noting that the spatial node update method described in the embodiment of the present invention can be implemented by an update platform, which is installed on the terminal as a software program and can perform human-computer interaction with the user. The target area may be a village in the city, a community, etc.; the community space node is an important concept in urban planning and design, which usually refers to a specific place or area in the city with intersection, connection and communication functions. Community space nodes can be squares, parks, transportation hubs, shopping centers, markets, cultural facilities, etc., which are important places for people to gather, communicate and move in the city. The degree of spatial enclosure refers to the degree to which the surrounding buildings of the spatial node enclose the spatial node through a spatial enclosure method. The spatial enclosure method refers to a way of making people have a centripetal and cohesive psychological feeling, and limiting an introverted void field with a physical entity as the boundary.

[0043] Specifically, the step S2 includes:

[0044] S21, obtaining surrounding buildings of each spatial node to obtain the enclosure degree of the surrounding buildings of the spatial node;

[0045] S22, obtaining the spatial enclosure type of each spatial node according to the enclosure degree of the surrounding buildings.

[0046] Exemplarily, in step S21, a monitoring and analysis model is pre-trained in an embodiment of the present invention. The monitoring and analysis model is pre-trained based on big data. The monitoring and analysis model can be a convolutional neural network. After the electronic map data is input into the monitoring and analysis model, a reference three-dimensional image of the spatial node can be selected from the electronic map data, thereby selecting the surrounding buildings of the spatial node in the reference three-dimensional image. The monitoring and analysis model will automatically output the surrounding buildings of the spatial node, such as shops and buildings. Alternatively, the image recognition technology in the AI ​​intelligent detection technology is used to select the reference three-dimensional image of the spatial node from the electronic map data, and the surrounding of the spatial node is automatically identified based on big data training to obtain the surrounding buildings of the spatial node. According to the surrounding buildings of each spatial node, the degree of enclosure of the surrounding buildings of the spatial node is obtained.

[0047] For example, in step S22, according to the difference in the degree of enclosure of the surrounding buildings of the spatial nodes, four spatial enclosure types are classified into single-sided building enclosure type, double-sided building enclosure type, three-sided building enclosure type and four-sided building enclosure type to obtain the spatial enclosure type of each spatial node. Figure 2 As shown, Figure 2 It is a schematic diagram of the structure of a space enclosure type provided by an embodiment of the present invention. A space node of the single-sided building enclosure type has only one side connected to the surrounding buildings, and the rest are connected to urban roads and main roads in the village, and the node accessibility is very good; most of the space nodes of the two-sided building enclosure type are triangular, two of which are enclosed by buildings, and the other side is adjacent to the main road in the village, and the node accessibility is good; the space node of the three-sided building enclosure type is enclosed by three sides of buildings, and the other side is adjacent to the main road in the village, and the node accessibility is good; the space node of the four-sided building enclosure type is enclosed by buildings on four sides, with limited internal ventilation and lighting, poor accessibility, and mainly walking. Some space nodes can allow motor vehicles to pass.

[0048] Specifically, the step S4 includes:

[0049] S41, selecting at least one target spatial relationship strategy from a preset spatial update strategy according to the spatial evaluation result of each spatial node; wherein the preset spatial update strategy sets a correspondence relationship between several groups of spatial evaluation results and spatial update strategies;

[0050] S42, using the target space update strategy to transform and update the corresponding space nodes.

[0051] Exemplarily, in step S41, the spatial evaluation result can be composed of the renewal potential score of the combination of spatial enclosure type, accessibility, commercial value, etc. For example, according to the renewal potential score, the corresponding relationship between the spatial evaluation result and the spatial renewal strategy is set. For example, a spatial node surrounded by four buildings is a spatial node that cannot be rebuilt after the original base is demolished. This type of spatial node has poor sanitary conditions and facilities, no management, poor accessibility, and extremely wasteful spatial resources. The renewal potential score is low. In the face of such conditions, the spatial renewal strategy is to improve the spatial environment and introduce purposeful commercial or public welfare institutions (such as introducing cultural and creative coffee, art galleries, etc. with purposeful industries in the shops around the spatial node), so that people can enter this spatial node purposefully and activate it. In fact, this type of spatial node is also an activity place for the surrounding residents. If the stores around the spatial node can introduce industries with their own IP, the spatial value will be greatly improved. For example, a spatial node surrounded by three buildings is large and currently is a parking lot. Since many mechanical parking lots have been set up in the project, parking is a very inefficient way of space efficiency, and the renewal potential score is average. Setting it up as a creative market will better attract people, whether from residents or outsiders, and it is a way to increase popularity and promote surrounding businesses. For example, the space node enclosed by double-sided buildings has wider roads on both sides and a better renewal potential score. Therefore, the space renewal strategy sets up some purposeful and relatively neutral businesses to attract people to enter. At the same time, it can be considered to connect the first floor to attract more people. This method is not only applicable to open public spaces, but also to the development of collectively held properties. For example, the space node enclosed by a single-sided building faces the main thoroughfare and has a high renewal potential score. The space renewal strategy needs to provide more rest and beautification space. Due to the street, the business around the space node is originally active, so the space node and the industry are more of an auxiliary industry function. At the same time, it is necessary to set up identifiable structures to make people recognizable when walking on the street.

[0052] For example, in step S42, the corresponding spatial nodes can be transformed and updated according to the target spatial update strategy through spatial simulation technology to obtain the specific effect after transformation and update (bird's eye view effect diagram). It is worth noting that in terms of urban spatial form, the renewable part is divided into different blocks, urban space is created on both sides of the main road, and the urban sense is shaped with complete and connected architectural space, while the bottom layer needs to be connected with the texture of the urban village on the slow flow line to form a small-scale commercial area.

[0053] Specifically, the preset space evaluation index system includes four dimensions: sharing, vitality, comfort, and safety.

[0054] Specifically, the step S3 includes:

[0055] S31, obtaining the reachability of each spatial node according to the spatial enclosure type;

[0056] S32, evaluating each spatial node according to the accessibility and a preset spatial evaluation index system to obtain a spatial evaluation result of each spatial node.

[0057] For example, through the investigation of urban villages, the enclosed space type is used as a classification standard, and the accessibility of different spaces is also reflected. For example, a spatial node surrounded by buildings on four sides means that its accessibility is the worst, while a single-sided enclosure is actually not considered an enclosure, and the surrounding areas are all roads. The accessibility of this space is very easy to find in a homogeneous urban village. Single-sided enclosures are generally on the side of the main street, while four-sided enclosures are located deeper in the village. After the classification and identification of public spaces, the spatial quality is then evaluated, and an evaluation system is formulated for this purpose. The embodiment of the present invention uses the four dimensions of "sharing, comfort, vitality, and safety" for evaluating public spaces and community creation to identify spaces, and derives 18 evaluation indicators from the four dimensions, as shown in Table 1. Table 1 is a preset spatial evaluation indicator system.

[0058] Table 1 shows the preset spatial evaluation index system

[0059] Evaluation indicators Meaning of evaluation indicators Is it easily accessible from the main street? Is it easy to access from the main street? How is the accessibility? Import and export quantity How many entrances and exits there are? The more entrances and exits, the better the accessibility. Degree of recognition Is the space recognizable? Lighting The light in a space is related to its orientation and obstructions. Occlusion Whether there is any shade from the sun, and to what extent Surface garbage Severity of surface garbage accumulation Water accumulation Severity of waterlogging Garbage collection route Is there a reasonable and appropriate way to collect and dispose of garbage? Greenery Greening degree Visual experience Is the visual experience comfortable and pleasant? Controls used Can the user control the use of the space without being disturbed by others or things? Space size Is the space pleasant, comfortable, and lively? Meaningful activities Whether meaningful activities are taking place or conducive to meaningful activities taking place Business atmosphere Whether there is business and whether the business atmosphere is strong Vacant units Whether the space is vacant or occupied and unused Traffic Traffic volume Activities where people stay Are people willing to stop and carry out activities? odor Is the smell pleasant and comfortable?

[0060] Each indicator is worth 10 points, for a total of 180 points. The lower the score, the worse the spatial evaluation result, and the higher the score, the better the spatial evaluation result. The scoring system of the embodiment of the present invention can consider the combination of investigation and evaluation, so the scoring is subjective, and no quantitative interval is set. For example, water accumulation, each person's subjective feelings may be different, or some people find water accumulation during the investigation, while others do not. So everyone's comparison framework is different. This scoring system can be applied to every investigation. It is the most superficial and simple evaluation system and is suitable for basic large-scale questionnaires. In other embodiments, an evaluation analysis model can be pre-trained, and the evaluation analysis model is pre-trained based on big data. The evaluation analysis model can be a convolutional neural network. After the accessibility of each spatial node and the preset spatial evaluation indicator system are input into the monitoring analysis model, the spatial evaluation result is output, which is not specifically limited here.

[0061] Furthermore, before executing step S2, the method further includes:

[0062] S201, optimize all spatial nodes to obtain optimized spatial nodes.

[0063] Exemplarily, the spatial nodes selected from the electronic map data in the embodiment of the present invention can be optimized to obtain optimized spatial nodes after on-site verification, field investigation, evaluation and inspection, and it can be found that some spatial nodes have changed, such as the addition of public welfare facilities (such as fitness equipment) and the merging of two nodes on opposite sides of the road into one.
