Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In one embodiment, a method for generating a ceiling lamp strip is provided, which is used for generating a lamp strip of a preset pattern on a ceiling model, the method does not affect the original structural size of the ceiling model, and the lamp strip lofting can be performed rapidly and accurately.

As shown in fig. 2, the method for generating the ceiling lamp band of the present embodiment includes:

step 1, obtaining a preset pattern of a lamp strip and a molding edge of the lamp strip required to be placed on a suspended ceiling model, wherein the preset pattern of the lamp strip comprises specifications of a lamp core and a lamp groove.

The modeling edge of the ceiling model in this embodiment is understood to be the contour edge of the ceiling model on the vertical projection plane, and if there are different areas (e.g., areas with different heights) of the ceiling model, the modeling edge should be the contour edge of each area on the vertical projection plane. To facilitate access to the molding edges, the molding edges are typically configured as a linked list for storage.

And 2, carrying out horizontal offset on the modeling edge on the suspended ceiling model according to the specification of the lamp trough to obtain a new offset edge.

The deviation of the molding edge is understood to be the deviation of the edge on the top plane of the suspended ceiling, as shown in fig. 3, the line indicated above in the drawing is the state after the deviation of the molding edge (in the drawing, 1 is the house type top surface, 2 is the molding edge after the deviation, and 3 is the molding edge of the suspended ceiling). Because the side in the suspended ceiling model is obtained by downwards stretching the suspended ceiling area, when the modeling edge deviates by the width of one lamp slot, the deviated modeling edge 2 is obtained by stretching the deviated modeling edge, namely the whole side is along with the deviation, and the bottom modeling edge 3 still maintains the original width to be the indication behind the lofting lamp strip.

Since the molding edge has various line types, in order to ensure that each line type can be effectively offset, in one embodiment, an offset manner of the molding edge is provided as follows:

And 3, judging whether each offset edge is intersected with an adjacent edge (the adjacent edge can be an unbiased molding edge or an offset molding edge), and if not, adopting edge repairing treatment. If the two areas are intersected, edge repairing is not needed, and the offset areas are directly taken.

Because the area on the suspended ceiling is connected in the anticlockwise direction, in order to better realize excessive connection with the modeling edge, the edge repairing is carried out anticlockwise in the application, and the anticlockwise area is formed with the original area. Also because of the counterclockwise connection, each line segment in the ceiling area is directional, whereby the starting and ending endpoints of each line segment can also be determined in a counterclockwise direction.

As shown in fig. 4 (the solid line in fig. 4 represents the original molding edge, the short horizontal line represents the molding edge after the offset, and the dotted line represents the new trimming), the trimming processing method provided in this embodiment is as follows:

case a: when the offset edge and the adjacent edge are straight and parallel, the starting end point of the previous edge and the ending end point of the next edge are connected in the anticlockwise direction, so that a new complementary edge is obtained.

case c: when the offset edge and the adjacent edge are both circular arcs, if the tangent line of the starting end point of the front circular arc of the two circular arcs is parallel to the tangent line of the ending end point of the rear circular arc in the anticlockwise direction, converting to the condition a for processing; if the tangent line of the starting end point of the front arc and the tangent line of the ending end point of the rear arc are not parallel in the anticlockwise direction, the process is switched to the condition b for processing.

The edge repairing treatment ensures that the suspended ceiling model has no discontinuous molding edge condition from the projection surface, namely, the phenomena of gaps, light leakage and the like of suspended ceiling caused by the offset of the molding edge are effectively avoided. However, the suspended ceiling is of a three-dimensional structure, so that an effective suspended ceiling model can be truly obtained only by carrying out three-dimensional surface compensation under the condition of two-dimensional edge compensation.

And 4, carrying out surface supplementing treatment on the suspended ceiling model with the offset edges, wherein the process is as follows:

if the side of the top surface, connected with the top surface of the house body, of the suspended ceiling model is deflected inwards, the specification from the top surface to the front of the deflection is supplemented, as shown in fig. 5, 1 is a house type top surface, 4 is a house type wall surface, 5 is a suspended ceiling, and a shadow surface corresponding to the first surface complementing area 6 is an area needing surface complementing; if the common modeling edges of different areas in the suspended ceiling model are shifted inwards, the horizontal areas between the common modeling edges before and after shifting are complemented, as shown in fig. 6, 5 is a suspended ceiling, the suspended ceiling is provided with two different areas with different heights, after the area with a lower surface is shifted, the light band area 7 is obtained, and the area with a higher surface is in a surface missing condition due to the shifting, so that the shadow surface corresponding to the second surface complementing area 8 is required to be complemented.

In the ceiling model of this embodiment, different areas are understood as two ceiling areas with different heights, and the common modeling edge refers to a modeling edge where two ceiling areas are abutted against each other, and after the common modeling edge of one area in the different areas is offset, the blank of the surface in the original abutting relationship is broken, so that the surface of the blank needs to be subjected to surface repairing treatment.

And b, adding a complementary surface to the hollow area formed after adding the new complementary edge in the step 3. Since the edge is repaired only on the two-dimensional plane in the step 3, the edge added in the step 3 cannot perform the shading effect of the suspended ceiling model in the three-dimensional space, and thus the three-dimensional surface repair, namely the offset side surface repair, needs to be obtained based on the two-dimensional edge repair stretching. As shown in fig. 7, the shadow surface corresponding to the third surface complement area 9 is the surface complement obtained by stretching the leftmost surface complement in fig. 4, and it can be seen that the surface blank of the shifted suspended ceiling is closed after the surface complement treatment.

And c, if the side surfaces of the different areas are not connected after the common modeling edges of the different areas in the suspended ceiling model are deflected inwards, supplementing the side surfaces between the common modeling edges before and after the deflection.

The offset of the molding edge carries the side surface and offset at the same time, so that the side elevation is possibly discontinuous, and the side surface is required to be complemented in the case.

The complementary surfaces may be two sides directly connected to the gaps for surface compensation, or may be regular complementary surfaces according to the original common molding edge and the offset common molding edge for surface compensation, for example, as shown in fig. 8 to 9, 51 and 52 refer to two different areas (a first area and a second area) of the suspended ceiling, 10 and 11 refer to two complementary side surfaces, 13 refer to the molding edge of the suspended ceiling after the different areas are offset, the common molding edge 12 is offset to the right side, the left side area remains unchanged after the common molding edge is offset to the left side, the right side area is reduced, so that a fault appears on the side surface between the left side area and the right side area, and during surface compensation, the left side area carries out surface compensation along the original common molding edge (namely, the third complementary surface area 10 corresponds to a shadow surface), and extends from the surface compensation to the tail part of the offset common molding edge of the right side (namely, the shadow surface area 11 corresponds to the fourth complementary surface area) for reducing structural variation of the original suspended ceiling.

After the modeling edge is shifted, a lofting area of the lofting lamp belt is obtained, and after the edge and the surface are repaired, the suspended ceiling basically maintains the original modeling, and the conditions of light leakage, fault and the like are avoided.

The manner of lofting the lamp strip in this embodiment is as follows:

The production in lamp area does not influence former furred ceiling's specification in this embodiment, through the skew to the molding limit, realizes carrying out the lamp area lofting on the basis that does not influence the original structure size of furred ceiling model, can guarantee that the designer need not to consider the size influence of lamp area to normal region even dysmorphism region when designing complicated furred ceiling light groove structure.

In order to increase the attractiveness, the decoration line is added to the suspended ceiling, and the offset, the complementary surface and the like of the suspended ceiling may affect the decoration line, so in another embodiment, the method for generating the suspended ceiling lamp strip further comprises the following adaptive adjustment of the decoration line on the suspended ceiling model:

As shown in fig. 10, the portion indicated by reference numeral 7 is a lamp strip area of a common molding edge, and a new complementary surface generated in the second complementary surface area 8 in the complementary surface case a is directly below the lamp strip area, and since there is a new complementary surface, the adjacent corner line 14 needs to be extended to the new complementary surface to ensure the aesthetic property of the suspended ceiling.

In another embodiment, a ceiling light band generation system is provided, namely a computer device, which may be a terminal. The computer device includes a processor, a memory, a network interface, a display screen, and an input device connected by a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities.

The computer program is executed by a processor to implement a method of generating a ceiling light band. The display screen of the computer equipment can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer equipment can be a touch layer covered on the display screen, can also be keys, a track ball or a touch pad arranged on the shell of the computer equipment, and can also be an external keyboard, a touch pad or a mouse and the like.
