Summary of the application

In the process of realizing the present disclosure, the inventor finds that, in the rendering process of the existing house decoration, the selection of the rendering point location is the point location when VR is manually shot; however, there are at least the following problems with manually determining rendering points: the manpower and material resources are wasted, and the house decoration effect cannot be accurately rendered. Therefore, a method for automatically generating rendering points is needed, and the automatically generated rendering points need to cover all corners of a room, so that a user can observe the whole appearance of the room decoration, the point distance cannot be too dense to improve the rendering efficiency, and all the points are required to be mutually communicated through the points.

Exemplary method

Fig. 1 is a flowchart illustrating a method for determining a rendering point of house decoration according to an exemplary embodiment of the present disclosure. The embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:

And 102, drawing a house type diagram of a house according to house information to be rendered, and drawing a decoration design to be rendered in a set position of the house type diagram to obtain a plane decoration diagram.

Optionally, the house information includes, but is not limited to, coordinate information of house hardware (e.g., walls, doors, windows, etc.), and in order to improve the rendering effect, the house information may also be thickness information of the house hardware; the decorative designs in this embodiment may include, but are not limited to, furniture, ceilings, carpeting, and the like that can affect the appearance of the room.

Step 104, determining a plurality of pre-selected points in the plane decoration map.

In one embodiment, after the locations of walls, doors, windows, and trim designs have been determined, a plurality of locations where rendering points can be set may be determined as pre-selected points in other selectable spaces; the position selection of the pre-selected points needs to avoid overlapping with the position coordinates of walls, doors and windows and the like, and cannot be selected on the decoration design.

And 106, determining at least one rendering point based on the plurality of pre-selected points according to the communication relation among the plurality of pre-selected points.

In this embodiment, operations such as merging and/or deleting a plurality of pre-selected points can be performed through a communication relationship between the plurality of pre-selected points, so that the obtained rendering points can render all rooms of the house with the least number of points.

The method for determining the rendering point of house decoration provided by the embodiment of the disclosure comprises the following steps: drawing a house type diagram of the house according to house information to be rendered, and drawing a decoration design to be rendered in a set position of the house type diagram to obtain a plane decoration diagram; determining a plurality of preselected points in the plan finishing map; determining at least one rendering point based on the plurality of pre-selected points according to a communication relationship between the plurality of pre-selected points; according to the embodiment, the rendering points are determined through the determination of the preselected points and the determination of the rendering points based on the communication relation among the preselected points, so that the automatic determination of the positions of the rendering points is realized, and manpower and material resources are saved.

As shown in fig. 2, step 104 may include the following steps, based on the embodiment shown in fig. 1, described above:

In step 1041, a legal area in the plan view is determined.

Step 1042, dividing the synthesized region to obtain a plurality of divided regions.

Step 1043, determining at least one pre-selected point in each of the plurality of partitioned areas, resulting in a plurality of pre-selected points.

In the embodiment, since the rendering points cannot be arranged in walls, doors and windows and cannot be arranged in furniture, firstly, the area in which the pre-selection points can be arranged in the plane decoration map needs to be determined, the position where the rendering points cannot be arranged is eliminated, the area where the pre-selection points are arranged is reduced, and the accuracy and the efficiency of the position of the rendering points which are determined later are improved; and at least one pre-selection point is respectively arranged in each partition area by partitioning the legal area, so that the coverage range of the pre-selection points can cover all rooms of a house, and the problem of incomplete rendering is avoided.

As shown in fig. 3, the step 1041 may include the following steps based on the embodiment shown in fig. 2, which is described above:

Step 301, performing expansion operation on all the walls and the areas where the decoration design objects are located in the plane decoration map according to the first set pixel length value, so as to obtain an expansion area.

The first set pixel length value is determined according to the minimum set distance between the wall and the decorative design and the rendering point.

At step 302, the portion of the planar decoration map other than the expansion area is determined as a legal area.

In this embodiment, in order to avoid the occurrence of redundant rendering points, a minimum set distance (which may be set according to practical situations, for example, 20 cm) between one rendering point and a wall and a decoration design may be set, and the minimum set distance is converted into an image according to an image conversion ratio (determined when a house pattern diagram of a house is drawn), so as to obtain a first set pixel length value; and performing expansion operation by using the first set pixel length value, wherein the obtained expansion region is a position which is in the minimum set distance range and does not need to be provided with a rendering point, so that other regions excluding the expansion region in the plane decoration map are legal regions which can be provided with pre-selected points. The expansion operation is to move the defined structural element (the first set pixel length value in the embodiment) in the whole image (the region where all the walls and the decoration design object are located in the embodiment) to each pixel point, and if the pixel value of the structural element is equal to at least one pixel of the corresponding pixel point on the image, the value of the pixel point is reserved; for example, in an alternative example, the legal area shown in fig. 4b may be obtained by performing an expansion operation based on the planar finishing map shown in fig. 4a.

As shown in fig. 5, the step 1042 may include the following steps, based on the embodiment shown in fig. 2, as described above:

And step 501, performing corrosion operation on the legal area based on the side length of the largest square included in the legal area to obtain a corrosion area.

Step 502, taking the maximum rectangle except the corrosion area in the legal area as a division area.

Step 503, judging whether the legal area includes a residual area except the division area, if so, taking the residual area except the division area in the legal area as a new legal area, and returning to execute step 501; otherwise, the segmentation is finished, and a plurality of segmented areas are obtained.

Alternatively, the divided area in the present embodiment may be a rectangular area, and the process of obtaining the divided area may include: performing corrosion operation by using square cores with larger side lengths, and dividing the residual maximum rectangle; then gradually reducing the side length of the kernel, continuing the corrosion operation on the rest part of the original legal area, and iteratively executing the steps until all areas of the legal area are segmented, so as to realize the segmentation of the legal area into a plurality of rectangular areas from large to small, for example, in an alternative example, the legal area shown in fig. 4b can be segmented to obtain a plurality of segmented areas as shown in fig. 4 c.

As shown in fig. 6, the step 1043 may include the following steps, based on the embodiment shown in fig. 2, as described above:

The first merging point is any merging point of the plurality of merging points, and the second merging point is other merging points except the first merging point of the plurality of merging points which are communicated with the first merging point and are closest to the first merging point.

In step 902, the first merging point or the second merging point is deleted, and all the merging points remaining after deletion are obtained, and the execution returns to step 901.

In step 903, the plurality of remaining merging points are used as a plurality of remaining points.
