Referring to fig. 2, fig. 2 is a flow chart of a building drawing splicing method provided in an embodiment of the present application, which is applied to an electronic device 101, and the building drawing splicing method includes the following operations.
Step 201, determining a first block in the original building drawing of the target building, wherein the first block meets a preset standard frame proportion.
The target building may be, for example, an underground garage, a swimming pool, etc., which is not limited herein.
Wherein, the original building drawing is a DWG drawing.
The preset standard frame proportion is 0.707, and the proportion of A4, A3 and A1 standard publication papers can be adapted.
Wherein the first tile is a rectangular region tile containing at least one build instance, the coordinate range of the rectangular region tile covering the coordinate range of each build instance.
In this possible example, the determining the first block meeting the preset standard frame proportion in the original building drawing of the target building includes: extracting a plurality of original image blocks in an original building drawing of a target building, wherein each original image block is used for carrying out graphic illustration on one or more building elements of the target building; determining a maximum bounding box of each original image block, wherein the bounding box is used for representing a minimum rectangular area covering the coordinate range of the current original image block; and screening a first image block which accords with the preset standard image frame proportion from the plurality of original image blocks.
In this example, the electronic device determines the maximum bounding box of the original image block of the original building drawing, and screens the image block according to the preset standard image frame proportion, so as to avoid confusion of the splicing result caused by mixing the unconventional image block into the image block to be spliced, and improve the splicing accuracy.
Step 202, cutting the graph block which is required to be cut but is not actually cut in the first graph block and indicated by the drawing editing attribute parameter, so as to obtain an updated second graph block.
When the drawing staff edits the image blocks, descriptive information of the drawing editing attribute parameters can be recorded to clearly indicate whether the current image block needs to be cut to adapt to subsequent image splicing, and the general drawing staff can cut the image block in advance to enable the original image block to be the cut image block, if the drawing staff forgets to cut the image block, the electronic equipment can identify the situation and automatically complete cutting to accurately adapt to subsequent splicing requirements.
Step 203, grouping the second tiles according to a layer relationship to obtain at least one tile group, where each tile group includes at least one second tile of the same layer, and layers of any two tile groups are different from each other.
Step 204, determining a target splicing block of each block group in the at least one block group, so as to obtain a target building drawing composed of at least one target splicing block.
The target spliced image block is an integral image block obtained by processing and splicing more than two second image blocks, and any two second image blocks in the more than two second image blocks are in direct intersection or indirect correlation.
In a specific implementation, the determining the target splicing block of each block group in the at least one block group, to obtain a target building drawing composed of at least one target splicing block includes:
performing the following operation for each of the at least one block group to obtain a target building drawing consisting of at least one target spliced block;
combining coordinate ranges of second image blocks of the image block group processed at present according to the direct intersection and/or indirect intersection relationship to obtain at least one reference spliced image block;
and screening target splicing blocks which accord with the preset lengthening frame proportion from the at least one reference splicing block.
The preset lengthened picture frame proportion is the picture frame proportion of a lengthened drawing prescribed by national standard specification.
For example, assuming that tile A (coordinate ranges [ (x 1, x 2), (y 1, y 2) ]) and tile B (coordinate ranges [ (x 3, x 4), (y 1, y 2) ]) directly intersect (x2.ltoreq.x3), tile B and tile C (coordinate ranges [ (x 5, x 6), (y 1, y 2) ]) directly intersect (x4.ltoreq.x5), tile A and tile C indirectly intersect. And (3) carrying out coordinate range combination through the direct intersection and/or indirect intersection relationship to obtain the transverse coordinate range of the block D as (x 1, x 6). The longitudinal coordinate range of the block D is (y 1, y 2), then the frame range of the block D is [ (x 1, y 1), (x 6, y 2) ].
In this example, the electronic device can perform tile merging based on the direct intersection and/or the indirect intersection relationship, and take the reference tile that meets the preset elongated frame proportion as the target tile.
In this possible example, the direct correlation refers to that the horizontal coordinate ranges of two second tiles intersect and the vertical coordinate ranges are the same, and the indirect intersection refers to that the horizontal coordinate ranges of two second tiles establish an indirect intersection relationship through the horizontal coordinate range of another second tile, and the vertical coordinate ranges are the same.
In one possible example, after the target tile matching the preset elongated frame proportion is selected from the at least one reference tile, the method further includes: and respectively carrying out edge line combination on each target splicing block according to the horizontal direction and the vertical direction to generate an inner border line of each target splicing block.
In a specific implementation, edge merging refers to: and merging the horizontal lines in the range of the currently processed target spliced block according to the rules of identical layers and identical Y values, merging the vertical lines in the range of the currently processed target spliced block according to the rules of identical layers and identical X values, searching for the upper, lower, left and right inner frame lines according to the blank side proportion of the A3 drawing as a standard, and obtaining the inner frame lines if the upper, lower, left and right inner frame lines find out the straight lines meeting the conditions.
It should be noted that the horizontal direction and the vertical direction described in the embodiments of the present application are relative concepts, that is, the horizontal direction and the vertical direction can be interchanged to adapt to the current scheme, and are not limited to the horizontal direction and the vertical direction of the drawing coordinates.
It can be seen that in the embodiment of the present application, the electronic device first determines a first image block in an original building drawing of a target building, where the first image block meets a preset standard frame proportion; secondly, cutting the graph block which is required to be cut but is not actually cut in the first graph block according to the drawing editing attribute parameter indication, and obtaining an updated second graph block; then, grouping the second image blocks according to the layer relation to obtain at least one image block group, wherein each image block group comprises at least one second image block with the same layer, and the layers of any two image block groups are different from each other; and finally, determining target splicing blocks of each block group in at least one block group, and obtaining a target building drawing composed of at least one target splicing block. Because only the identical picture blocks of the picture layer are likely to be spliced into the picture frame, the spliced picture blocks formed after the picture layer is divided can avoid mixing of other picture layer picture blocks, and the cutting detection can avoid drawing confusion caused by the fact that the picture blocks which are actually forgotten to be cut are spliced by the drawing staff although the marks are needed to be cut, thereby being beneficial to improving the accuracy and the comprehensiveness of splicing the building drawing.
