In various embodiments of the present application, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

An embodiment of the present application provides a method for acquiring lighting information, which is shown in fig. 1 and includes:

step 101, building a building surrounding shell which surrounds a target building and has the same outline as the target building.

According to the method for acquiring lighting information provided by the embodiment of the application, firstly, a building enclosure shell which surrounds a target building and has the same outline as the target building is constructed for the target building in a building according to the building parameters of the target building. Wherein, the building surrounding shell surrounds the side of the target building and does not surround the top and the bottom of the target building. The building plate can comprise a plurality of buildings, and any one building can be used as a target building. The building enclosure shell constructed for the target building has the same shape as the target building and a size slightly larger than the target building.

And 102, determining a plurality of light receiving grids corresponding to the surrounding surface of the building surrounding shell.

After building a building enclosure shell with the same profile as the target building based on the building parameters of the target building, light receiving grids corresponding to each enclosure surface of the building enclosure shell can be determined aiming at the building enclosure shell so as to obtain a plurality of light receiving grids corresponding to the building enclosure shell. Each surrounding surface of the building surrounding shell is matched with each side surface of the target building one by one, and the number and the size of the light receiving grids corresponding to different surrounding surfaces can be different.

And 103, determining the lighting condition of the target building within the sampling date according to the light receiving states of the light receiving grids corresponding to the sampling times of the sampling date, wherein the sampling dates are multiple.

After the corresponding light receiving grids are determined for the building enclosure, the light receiving conditions of the light receiving grids can be acquired at a plurality of sampling dates. The method specifically comprises the following steps: and acquiring light receiving states of the plurality of light receiving grids corresponding to a plurality of sampling moments of the current sampling date for each sampling date, and determining the lighting condition of the target building within the current sampling date according to the light receiving states of the plurality of light receiving grids corresponding to the plurality of sampling moments of the current sampling date. The lighting condition of the target building within the sampling date may include at least one of a light receiving period of the light receiving grid within the sampling date and a light receiving period within the sampling date.

The plurality of sampling dates may be specific solar terms, or may be a plurality of sampling dates determined according to a preset rule. For example, the plurality of sampling dates include spring equinox, summer solstice, autumn equinox, and winter solstice of a certain year; alternatively, the plurality of sample dates comprises the first day of each of the 12 months of the year. Of course, multiple sampling dates may be used, and are not listed here.

For different sampling dates, the number of corresponding sampling moments can be the same or different, and correspondingly, the corresponding specific moments can also be different. For a plurality of sampling moments in the sampling date, the duration of an interval between any two adjacent sampling moments may be a fixed value, or any two adjacent sampling moments may form a sampling moment group, and the interval durations (the interval durations of two sampling moments) corresponding to different sampling moment groups are different. For the second case, the interval duration between two adjacent sampling moments may vary according to a preset rule on the time axis. For example, the time duration between two adjacent sampling instants on the time axis gradually increases or decreases, the time duration between two adjacent sampling instants on the time axis decreases or increases during the period of strong light, the time duration between two adjacent sampling instants on the time axis increases first and then decreases, etc., although other embodiments are possible when the time duration varies according to the preset rule, which are not listed here. For convenience of description, the embodiment of the present application takes an interval duration between two adjacent sampling time instances as a fixed value.

In this embodiment, the first sampling date is associated with the target date, and the first sampling date is a date associated with the target date in the plurality of sampling dates, where the association is understood to mean that the lighting conditions are most similar. Aiming at a target building, a corresponding building model needs to be constructed, map resources corresponding to all light receiving grids are determined according to the lighting condition of the target building in a first sampling date based on a first lighting checking instruction of a user, and then map processing is performed on the building model corresponding to the target building based on the map resources so as to display the lighting condition of the target building in the target date through the building model corresponding to the target building.

When a first lighting checking instruction which is executed by a user on a target application program and indicates that the lighting condition of a target building in a target date is checked is received, based on the first lighting checking instruction, according to the lighting condition of the target building in a first sampling date, mapping processing is carried out on a building model corresponding to the target building, the building model subjected to mapping processing is displayed on an application program interface of the target application program, and the user can conveniently know the lighting condition of the target building through the building model.

The first lighting viewing instruction may be input by a user to a lighting control corresponding to the target building, and the input form includes but is not limited to click input, press input, slide input, specific action input, and the like. Each building can be corresponding to a lighting control; the multiple buildings can correspond to the same lighting control, a user triggers the display of multiple building identifications after inputting the lighting control, and the building corresponding to the selected building identification is determined as a target building based on the selection of the user in the multiple building identifications, so that the lighting condition of the target building is displayed.

The target date in this embodiment may be a current date on which the first lighting viewing instruction is received, or may be a specific date selected by the user, where the specific date may be a history date or a date corresponding to a day in the future, and the lighting condition of the target building within the target date is displayed based on the target date selected by the user, so that the lighting condition of the target building on the selected date is flexibly displayed for the user. For example, after clicking the lighting control, the user may trigger the display of a date list, and the date list may be updated based on the user's operation, and the target date may be determined based on the user's selection in the date list.

In the implementation process of the application, a plurality of light receiving grids corresponding to the building surrounding shell are determined by constructing the building surrounding shell which surrounds the target building and has the same profile as the target building, and the lighting condition of the target building in each sampling date is determined according to the light receiving states of the plurality of light receiving grids corresponding to a plurality of sampling moments of each sampling date, so that the relatively accurate lighting condition can be obtained based on the building surrounding shell which has the same shape as the target building; when a first lighting checking instruction which aims at a target building and indicates that the lighting condition in the target date is checked is received, according to the lighting condition of the target building in the first sampling date related to the target date, mapping processing is carried out on a building model corresponding to the target building, the building model subjected to mapping processing is displayed, and a user can know the lighting condition of the target building through the building model conveniently.

The following describes a process of constructing a building enclosure, and when constructing a building enclosure that encloses a target building and has the same contour as the target building, the process includes:

determining a first polygon corresponding to the target building according to the building parameters of the target building, wherein the first polygon is a polygon corresponding to the target building on a horizontal plane and comprising a plurality of vertexes;

for each vertex of the first polygon, determining an outward expansion vertex corresponding to the vertex;

aiming at a plurality of outward-expanding vertexes, connecting two adjacent outward-expanding vertexes to determine a second polygon surrounding the first polygon;

and determining the building enclosure shell according to the second polygon and the height of the target building.

When constructing the building enclosure shell corresponding to the target building, first, a first polygon corresponding to the target building on a horizontal plane is determined based on the building parameters of the target building, which can be understood as a polygon corresponding to the target building observed from a top view angle, for example, as shown in fig. 2, a specific example of the polygon determined when the target building is observed from a top view angle. It should be noted that the first polygon in this embodiment may be a minimum polygon that surrounds all the corresponding outlines of the target building on the horizontal plane.

After the first polygon is determined, for each vertex of the first polygon, an out-extended vertex corresponding to the vertex is determined. When determining the outward expansion vertex corresponding to the vertex for each vertex of the first polygon, the method includes: for each vertex, constructing a parallelogram according to a first line segment and a second line segment corresponding to the vertex, and determining a first diagonal line corresponding to the vertex in the parallelogram; and determining an outward expansion vertex with a preset distance from the vertex on the first diagonal or the reverse extension line of the first diagonal.

Aiming at each vertex of the first polygon, when an extended vertex corresponding to the vertex is determined, a parallelogram is constructed according to a first line segment and a second line segment corresponding to the vertex, the first line segment and the second line segment are used as two adjacent sides of the parallelogram, when the parallelogram is constructed, parallel lines parallel to the first line segment and parallel lines parallel to the second line segment are made, and then the parallelogram is determined.

After the parallelogram is determined, a target vertex opposite to the vertex in the parallelogram is determined, specifically, a connecting line between the target vertex and the current vertex is a diagonal line of the parallelogram, and the diagonal line is a first diagonal line corresponding to the current vertex. Referring to fig. 3, a specific illustration of constructing a parallelogram according to the line segments L1 and L2 corresponding to the point P is shown, and the point Q is a target vertex.

On the first diagonal line, taking the current vertex as a starting point, determining a point with a preset distance from the vertex, wherein the determined point is an outward expansion vertex; or, on the reverse extension line of the first diagonal line, taking the current vertex as a starting point, determining a point with a preset distance from the vertex, wherein the determined point is the outward expansion vertex. The first polygon comprises a first type of vertex and a second type of vertex, the parallelogram corresponding to the first type of vertex is positioned inside the first polygon, and the parallelogram corresponding to the second type of vertex is positioned outside the first polygon. In FIG. 2, P1 is a first type of vertex and P2 is a second type of vertex. The outward expansion vertex corresponding to the vertex of the first type is positioned on the reverse extension line of the diagonal line, and the outward expansion vertex corresponding to the vertex of the second type is positioned on the diagonal line.

After the outward expansion vertex corresponding to each vertex is determined for the first polygon, any two adjacent outward expansion vertices are connected according to the obtained multiple outward expansion vertices, and a second polygon surrounding the first polygon is determined. After a second polygon surrounding the first polygon is determined, for each contour line of the second polygon, a surrounding surface is determined according to the current contour line and building height information corresponding to the current contour line based on the determined second polygon, and a building surrounding shell is determined according to the surrounding surface corresponding to each contour line.

According to the implementation process, the first polygon is determined according to the building parameters of the target building, the outward-extended vertexes corresponding to the vertexes of the first polygon are determined, the second polygon is determined based on the outward-extended vertexes, the building enclosure is determined according to the second polygon and the building parameters of the target building, the building enclosure corresponding to the target building can be determined based on the real building parameters, and then the relatively accurate lighting condition can be obtained based on the light receiving condition of the light receiving grid corresponding to the building enclosure.

The following description is directed to a process of determining a plurality of light receiving grids corresponding to a building enclosing shell, and when determining a plurality of light receiving grids corresponding to an enclosing surface of the building enclosing shell, the process includes:

aiming at each line segment of the second polygon, determining a final segmentation length corresponding to the line segment according to a corresponding preset segmentation length and a length corresponding to the line segment; for each line segment, determining a light receiving grid corresponding to a first surrounding surface according to the final segmentation length corresponding to the line segment and the first surrounding surface corresponding to the line segment; the number of the light receiving grids corresponding to each floor in the first surrounding surface is the same.

For each line segment of the second polygon, it corresponds to a preset segmentation length and a tolerance. And when the final segmentation length corresponding to the current line segment is determined, determining the final segmentation length corresponding to the current line segment according to the preset segmentation length corresponding to the current line segment and the length corresponding to the current line segment. The specific calculation method is as follows: calculating the ratio of the length corresponding to the current line segment to a preset segmentation length corresponding to the current line segment to obtain segmentation parts (integers), if the remainder is less than or equal to the corresponding tolerance, determining the obtained segmentation parts as the final parts, and determining the final segmentation length based on the preset segmentation length and the remainder; if the remainder is greater than the corresponding tolerance, then the number of split copies is incremented by 1 and the final split length is determined. For example, if the length corresponding to the current line segment is 5m, and the preset segmentation length is 2m, the number of segmentation copies is 2 through calculation, and the remainder is 1m, and 1m is greater than the corresponding tolerance of 0.003 m, the number of segmentation copies is determined to be 3, and the final segmentation lengths are 1.66 m, and 1.68 m. Or, if the length corresponding to the current line segment is 4.001m, and the preset segmentation length is 2m, the number of segmentation parts is 2 through calculation, the remainder is 0.001m, and the number of segmentation parts is 0.001m and is less than the corresponding tolerance of 0.003 m, the number of segmentation parts is determined to be 2, and the final segmentation lengths are 2m and 2.001 m.

In this embodiment, after the final division length corresponding to each line segment of the second polygon is determined, a subsequent process of determining the light receiving mesh may be performed; after the final division length corresponding to the current line segment is determined for any one line segment, the light receiving mesh corresponding to the corresponding first bounding surface may be determined for the current line segment.

In this embodiment, the preset segmentation lengths and the tolerances corresponding to different line segments may be different. Referring to fig. 4, the final segmentation length is determined for each of the different line segments of the second polygon, and the segmentation is performed based on the final segmentation length.

When determining the light receiving grid corresponding to the first surrounding surface according to the final division length corresponding to the line segment and the first surrounding surface corresponding to the line segment, the method comprises the following steps: and dividing the first surrounding surface based on the floor number corresponding to the first surrounding surface and the final division length corresponding to the line segment to obtain the light receiving grid corresponding to the first surrounding surface.

For any line segment, after determining the final division length and the final division number corresponding to the line segment, the first surrounding surface may be divided based on the floor number corresponding to the first surrounding surface corresponding to the line segment, the obtained number of the division is the same as the floor number, and then the first surrounding surface is divided according to the final division length corresponding to the line segment. That is, the first surrounding surface may be divided into the floor in the height direction, the first surrounding surface may be divided into the final division lengths in the length direction perpendicular to the height direction, and the light receiving cells corresponding to the first surrounding surface may be obtained by performing the division twice in sequence. Or the division can be performed according to the final division length corresponding to the line segment, and then the division can be performed according to the floor number, at this time, the division is performed according to the final division length in the length direction, and then the division is performed according to the floor in the height direction.

In the above implementation process, the first surrounding surface may be divided based on the number of floors and the final division length to obtain the corresponding light receiving grid, so as to determine the light receiving condition of the floor corresponding to the target floor based on the light receiving condition of the light receiving grid.

In an embodiment of the present invention, the determining the lighting condition of the target building within the sampling date according to the light receiving states of the light receiving grids corresponding to the sampling times of the sampling date includes: acquiring light receiving states corresponding to the plurality of light receiving grids at each sampling time of the sampling date; for each light receiving grid, determining the light receiving time length corresponding to the light receiving grid on the sampling date according to the light receiving states corresponding to the light receiving grid on a plurality of sampling moments of the sampling date, and/or determining the light receiving time period corresponding to the light receiving grid on the sampling date; and determining the lighting condition of the target building within the sampling date according to the light receiving duration corresponding to the sampling date and/or the light receiving period corresponding to the sampling date.

After the division of the light receiving grids is completed and a plurality of light receiving grids corresponding to the building surrounding shell are determined, the light receiving states corresponding to the plurality of light receiving grids can be obtained at each sampling time of a plurality of sampling dates; then, for each light receiving grid, the light receiving states of the light receiving grid corresponding to a plurality of sampling moments are counted, the lighting condition of the target building within the sampling date is determined according to the light receiving states of the light receiving grids corresponding to the sampling moments, and the lighting condition can be determined based on the counting of the light receiving states of the light receiving grids.

When the light receiving state of the light receiving grid is obtained, the light receiving state of the light receiving grid can be determined based on the intersection condition of the target ray corresponding to the light receiving grid and the surrounding buildings, the target ray is determined based on the center of the light receiving grid and the sunlight direction, and when the target ray intersects with the surrounding buildings, the light receiving grid is determined not to receive light.

The target ray corresponding to the light receiving grid is determined based on the center of the light receiving grid and the sunlight direction, and specifically is the ray determined by taking the center of the light receiving grid as a starting point and extending in the opposite direction of the sunlight direction. When the target ray corresponding to the light receiving grid is intersected with the surrounding buildings, the light receiving grid is determined to be shielded, the light receiving grid is in an unreceived state, otherwise, the light receiving grid is determined to be in a light receiving state, the surrounding buildings corresponding to the target building can comprise buildings in a preset area range with the target building as the center, and related building data of the surrounding buildings need to be acquired, so that the intersection condition of the target ray corresponding to the light receiving grid and the buildings is determined based on the related building data. When the intersection condition of the target ray corresponding to the light receiving grid and the building is determined, the intersection condition of the target ray and the wall surface of the building can be determined.

In the present embodiment, the lighting condition of the target building within the sampling date may include at least one of a light receiving period of the light receiving grid within the sampling date and a light receiving period of the light receiving grid within the sampling date. For each light receiving grid, the light receiving time length corresponding to the sampling date of the light receiving grid can be determined according to the light receiving state corresponding to the light receiving grid at a plurality of sampling moments of the sampling date, and/or the light receiving time period corresponding to the sampling date of the light receiving grid can be determined.

The following describes the procedures of determining the light receiving time period and the light receiving period, respectively. In the embodiment of the present application, a process of determining a light receiving time length and a light receiving period of a light receiving grid is described by taking a time length of an interval between any two adjacent sampling times as an example of a fixed value. For example, the interval between any two adjacent sampling moments is 30 minutes, the sampling date corresponds to 24 sampling moments, for any light receiving grid, if the light receiving grid is in the light receiving state at the current sampling moment, the light receiving grid is considered to be in the light receiving state within 30 minutes in the future, and if the light receiving grid is in the non-light receiving state at the current sampling moment, the light receiving grid is considered to be in the non-light receiving state within 30 minutes in the future, and the light receiving time length and/or the light receiving period of the light receiving grid within one day (within the sampling date) can be determined based on the principle. Of course, the light receiving time period and/or the light receiving period may also be determined in other possible ways, which are not further listed here.

Because the target building comprises a plurality of light receiving grids, the lighting condition of the target building within the sampling date can be determined after the light receiving duration corresponding to the sampling date of the plurality of light receiving grids is acquired and/or the light receiving period corresponding to the sampling date is acquired.

In the implementation process of the application, the light receiving duration corresponding to the sampling date of the plurality of light receiving grids is counted, so that a user can conveniently know the light receiving duration of the corresponding area of the target building in one day; through counting the light receiving time periods corresponding to the plurality of light receiving grids in the sampling date, the user can know the light receiving time period of the area corresponding to the target building in one day conveniently.

In an embodiment of the present application, the lighting condition of the target building within the first sampling date includes light receiving periods corresponding to the plurality of light receiving grids and/or light receiving periods corresponding to the plurality of light receiving grids;

the responding to the first lighting viewing instruction for the target building, and performing mapping processing on a building model corresponding to the target building according to the lighting condition of the target building within a first sampling date, wherein the mapping processing includes at least one of the following steps:

responding to the first lighting viewing instruction, determining a mapping mode corresponding to each light receiving grid according to the light receiving duration of the light receiving grids in the first sampling date, and mapping the building model according to the mapping modes corresponding to the light receiving grids;

generating chartlet data which represents lighting periods and corresponds to each light receiving grid according to the light receiving periods corresponding to the light receiving grids on the first sampling date in response to the first lighting viewing instruction, and carrying out chartlet processing on the building model according to the chartlet data corresponding to the light receiving grids respectively;

and the first sampling date is the same as or similar to the lighting parameter corresponding to the target date.

In this embodiment, the lighting condition of the target building within the first sampling date includes a light receiving period corresponding to the plurality of light receiving grids and/or a light receiving period corresponding to the plurality of light receiving grids. The lighting condition of the target building within the target date is the lighting condition of the target building within the first sampling date associated with the target date.

The lighting parameter corresponding to the first sampling date is the same as or similar to the lighting parameter corresponding to the target date, and the lighting parameter can be the solar altitude. That is, the lighting condition of the target building within the first sampling date is determined as the lighting condition within the target date by determining the first sampling date associated with the target date based on the first lighting viewing instruction of the user indicating to view the lighting condition of the target building within the target date.

The association of the first sampling date with the target date is described below. The first sampling date and the target date may be the same date of different years, such as the target date of 2022 years, 6 months and 18 days, and the first sampling date may be 2021 years, 6 months and 18 days; the first sampling date may be the day or days before the target date, when the solar altitude of the first sampling date is similar to that of the target date; the first sampling date and the target date can be the same solar term of different years, for example, the target date is 2022 years summer solstice, and the first sampling date is 2021 years summer solstice. Of course, the first sampling date and the target date may be associated in other forms, as long as the solar altitude angles of the two are ensured to be the same or similar.

Aiming at the condition that the lighting condition comprises the light receiving duration corresponding to a plurality of light receiving grids, when the building model corresponding to the target building is subjected to mapping processing according to the lighting condition of the target building in the first sampling date, the mapping mode corresponding to each light receiving grid is determined according to the light receiving duration of the plurality of light receiving grids in the first sampling date, the mapping modes corresponding to different light receiving durations can be distinguished, and then the building model is subjected to mapping processing according to the mapping modes corresponding to the plurality of light receiving grids. When mapping processing is carried out, a mapping relation between the light receiving grid and the building model is established, and mapping is carried out based on the mapping relation.

The distinction of the map patterns can be color distinction, shape distinction or image distinction, and of course, other distinction forms are also possible. For example, the light receiving grid with the light receiving duration of more than 8 hours corresponds to a red mapping pattern, the light receiving grid with the light receiving duration of 6 to 8 hours corresponds to a yellow mapping pattern, the light receiving grid with the light receiving duration of 4 to 6 hours corresponds to an orange mapping pattern, and the light receiving grid with the light receiving duration of less than 4 hours corresponds to a green mapping pattern. For example, referring to FIG. 5, a particular illustration of a building model is presented in different colors. Or the light receiving grid with the light receiving time of more than 8 hours corresponds to a square chartlet pattern, the light receiving grid with the light receiving time of 6 to 8 hours corresponds to a circular chartlet pattern, the light receiving grid with the light receiving time of 4 to 6 hours corresponds to a triangular chartlet pattern, and the light receiving grid with the light receiving time of less than 4 hours corresponds to a diamond chartlet pattern; under the condition, the user can know the lighting time of each region of the target building conveniently based on the mapping shape corresponding to each region of the building model. Or the light receiving grid with the light receiving time length of more than 8 hours corresponds to the cartoon character A chartlet style, the light receiving grid with the light receiving time length of 6-8 hours corresponds to the landscape A chartlet style, the light receiving grid with the light receiving time length of 4-6 hours corresponds to the cartoon character B chartlet style, and the light receiving grid with the light receiving time length of less than 4 hours corresponds to the landscape B chartlet style; under the condition, the user can know the lighting time of each region of the target building conveniently based on the mapping content corresponding to each region of the building model.

When the building model corresponding to the target building is subjected to mapping processing according to the lighting condition of the target building within the first sampling date, mapping data representing lighting periods corresponding to each light receiving grid is generated according to the light receiving periods corresponding to the light receiving grids on the first sampling date, and the building model is subjected to mapping processing according to the mapping data corresponding to the light receiving grids. The mapping data corresponding to the light receiving grid may include a light receiving period corresponding to the light receiving grid, for example, the mapping data includes 9 to 12 points and 14 to 16 points. When the building model is subjected to mapping processing according to the mapping data respectively corresponding to the plurality of light receiving grids, a text image is generated according to the mapping relation between the light receiving grids and the building model and the mapping data (which can be understood as text data) corresponding to the light receiving grids, and the mapping processing is carried out on the corresponding area of the building model according to the text image.

The text image comprises text content and a background area, the background area can be displayed in a preset transparency mode, when the corresponding area of the building model is subjected to mapping processing according to the mapping mode of the light receiving grid and mapping data, the display of the mapping mode can not be influenced due to the fact that the background area of the text image is the preset transparency mode, the text content and the mapping mode can be overlaid at the moment, and the mapping mode serves as the background of the text content.

In the implementation process, when the first lighting checking instruction is received, the chartlet pattern is determined based on the light receiving duration of the light receiving grid, and/or the chartlet data is determined based on the light receiving time period of the light receiving grid, and the chartlet processing is performed on the building model according to at least one of the chartlet pattern and the chartlet data, so that a user can conveniently know the light receiving duration based on the chartlet pattern and/or know the light receiving time period based on the chartlet data.

In an embodiment of the present application, the lighting condition includes a light receiving duration corresponding to the plurality of light receiving grids and/or a light receiving period corresponding to the plurality of light receiving grids, and after the building model subjected to mapping is displayed, at least one of the following schemes is further included:

under the condition that a second lighting checking instruction for indicating to check a first light receiving grid is received, marking a first area in the building model in response to the second lighting checking instruction, wherein the first light receiving grid is a light receiving grid with the light receiving duration within a first time duration range, and the first area is an area corresponding to the first light receiving grid in the building model;

under the condition that a third lighting viewing instruction for indicating viewing of a second light receiving grid is received, a second area in the building model is marked in response to the third lighting viewing instruction, the second light receiving grid is a light receiving grid with a light receiving time period within a first time period, and the second area is an area corresponding to the second light receiving grid in the building model.

When the lighting condition comprises the light receiving duration corresponding to the plurality of light receiving grids, after the chartled building model is displayed, under the condition that a second lighting viewing instruction for indicating to view a first light receiving grid with the light receiving duration within a first time duration range is received, a first area matched with the first light receiving grid in the building model is marked in response to the second lighting viewing instruction, so that a user can view the first area corresponding to the first light receiving grid with the light receiving duration within the first time duration range. Specifically, when the building model subjected to mapping processing is displayed, the light receiving duration control can be displayed, a plurality of light receiving duration options are displayed based on the input of the user to the light receiving duration control, and each light receiving duration option corresponds to a light receiving duration range. Referring to fig. 6, in order to show a plurality of options of light receiving duration when the building model is displayed, building identification and selectable dates are also displayed in fig. 6. And after the user selects one light receiving duration option, determining that a second lighting checking instruction is received, determining a first light receiving grid corresponding to the selected light receiving duration option based on the second lighting checking instruction, and marking a first region matched with the first light receiving grid in the building model. For example, the number of the light receiving time duration options is 4, the light receiving time duration options respectively correspond to the light receiving time duration being larger than 8 hours, the light receiving time duration being between 6 and 8 hours, the light receiving time duration being between 4 and 6 hours and the light receiving time duration being smaller than 4 hours, when the user selects the light receiving time duration option corresponding to the light receiving time duration between 6 and 8 hours, a first light receiving grid with the light receiving time duration being between 6 and 8 hours is determined, and a first area matched with the first light receiving grid in the building model is marked. The first area in the building model is marked through the second lighting checking instruction based on the user, so that the user can conveniently select the length of light receiving time and check the corresponding house source in the target building.

When the lighting condition comprises a light receiving period corresponding to a plurality of light receiving grids, after the chartled building model is displayed, in the case of receiving a third lighting viewing instruction for indicating to view a second light receiving grid of the light receiving period in the first period, a second area matched with the second light receiving grid in the building model is marked in response to the third lighting viewing instruction, so that a user can view the second area corresponding to the second light receiving grid of the light receiving period in the first period. Specifically, when the building model subjected to mapping processing is displayed, a light receiving time period control can be displayed, a plurality of light receiving time period options are displayed based on input of a user to the light receiving time period control, and each light receiving time period option corresponds to one light receiving time period. Referring to fig. 7, in order to show options of a plurality of light receiving periods when a building model is displayed, a building mark and selectable dates are also displayed in fig. 7. And after the user selects one light receiving period option, determining that a third lighting viewing instruction is received, determining a second light receiving grid corresponding to the selected light receiving period option based on the third lighting viewing instruction, and marking a second region matched with the second light receiving grid in the building model. For example, the light receiving period options are 5, which correspond to 7 to 9, 9 to 12, 12 to 14, 14 to 16, and 16 to 19, respectively, when the user selects the light receiving period option corresponding to 9 to 12, the second light receiving grid in the light receiving state at 9 to 12 is determined, and the second area in the building model matching with the second light receiving grid is marked. The second area in the building model is marked based on the third lighting viewing instruction of the user, so that the user can conveniently select the light receiving time period to view the corresponding house source in the target building.

The second lighting viewing instruction and the third lighting viewing instruction may be lighting viewing instructions for a target date or lighting viewing instructions for other dates.

When the lighting condition includes the light receiving duration and the light receiving period corresponding to the multiple light receiving grids, a first region matched with the first light receiving grid in the building model can be marked based on the second light receiving check instruction, a second region matched with the second light receiving grid in the building model can be marked based on the third light receiving check instruction, and the marking of the first region can be cancelled when the second region is marked, or the marking of the first region is reserved, and different marking patterns are adopted to mark the second region.

In the implementation process of the application, the user can conveniently select the light receiving duration and check the corresponding house source in the target building by marking the first area corresponding to the first light receiving grid based on the selection of the light receiving duration by the user; the second area corresponding to the second light receiving grid is marked based on the selection of the user on the light receiving time period, so that the user can conveniently select the light receiving time period and check the corresponding house source in the target building.
