[0036] This embodiment provides a technical solution of the wall recognition method. The wall recognition method is executed by a wall recognition device, and the wall recognition device is usually integrated in a physical computing device.

[0037] see figure 1 , the wall recognition method includes:

[0038] S11. Obtain the floor plan uploaded by the user.

[0039] The operating object of the wall recognition method provided in this embodiment is the designed and drawn house type map. figure 2 An example of a floor plan is shown. The floor plan is also called the interior design drawing of the building. These types of units Figure 1 These are generally drawn using CAD applications. For example, the floor plan can be a DXF file or a DWG file drawn using AutoCAD software. The floor plan can also be an image file (such as an image file in the format of JPG, PNG, etc.) that is exported after the drawing is completed using a CAD application program.

[0040] In this emb...

[0053] Based on the above-mentioned embodiments of the present invention, this embodiment further provides a technical solution for grid operation in the wall recognition method. In this technical solution, rasterizing the house type map includes: determining the shape and size of the grid unit; and rasterizing the house type map according to the determined shape and size of the grid unit.

[0054] see image 3 , rasterizing the floor plan includes:

[0055] S31. Determine the shape and size of the grid unit.

[0056] The rasterization is to use different grid units to cut the floor plan. The grid cells can have different shapes and different sizes. For example, the grid unit can be used as Figure 4A The square shown, can also be used as Figure 4B A regular hexagon is shown. Taking a square grid unit as an example, the side length of the grid unit may be 1 cm or 1.5 cm.

[0057]However, when determining the size of the grid unit, one thing needs special attention, tha...

[0062] This embodiment further provides another technical solution of the wall identification method based on the above-mentioned embodiments of the present invention. In this technical solution, the wall identification method further includes: displaying the wall area to the user after identifying the wall area from the gridded floor plan according to the location point information.

[0063] see Figure 5 , the wall recognition method includes:

[0064] S51. Obtain the floor plan uploaded by the user.

[0065] S52. Rasterizing the floor plan.

[0066] S53. Display the rasterized floor plan to the user.

[0067] S54. Acquire the position points belonging to the wall area selected by the user.

[0068] S55. According to the information of the position point, identify the wall area from the gridded floor plan.

[0069] S56. Display the wall area to the user.

[0070] In this embodiment, after the wall area in the floor plan is recognized, it is necessary to continue to dis...

Abstract

An embodiment of the invention discloses a wall recognition method and device. The wall recognition method comprises the steps of acquiring a house type image uploaded by a user; rasterizing the house type image; displaying the rasterized house type image to the user; acquiring a location point belonging to a wall area and selected by the user; recognizing the wall area from the rasterized house type image according to the information of the location point. According to the wall recognition method and device provided by the embodiment, the building wall is recognized through simple interaction between a webpage front end and a background server, not only is a calculation simple, but also higher recognition accuracy is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of architectural interior design, and in particular to a wall recognition method and device. Background technique [0002] With the popularization of the application of computer technology, in the field of architectural design, more and more architectural design work is completed by computer-aided design (Computer-aided design, CAD) application program on the computer. [0003] For the building interior space design drawing completed by CAD application program, identifying the interior wall of the building is of great significance to the calculation of indoor area, heating design, air supply design, ventilation and air conditioning system design, etc. However, most of the existing wall recognition methods recognize the wall according to the image features on the design drawing, the calculation process is complicated, and the recognition accuracy is not high.
