Problems solved by technology

[0003] The existing house-type map recognition technology or method does not have a complete recognition method for the basic characteristics of the house type, such as: walls, doors, windows, balconies, etc., resulting in a lack of a large amount of foundation for the final display effect, and the display effect is not good. good
In addition, some feature vector databases are pre-established and processed by matching with the database. The huge database will occupy more memory, which is not enough for mobile terminals with small memory such as mobile phones.
At the same time, the obtained feature data does not support the re-editing function. The type, material, and size of the features in the displayed 3D model cannot be changed, and the display effect is single, which cannot meet the actual needs of users.

Embodiment Construction

[0044] like figure 1 As shown, a parametric re-editable modeling method for floor plan, which specifically includes the following steps:

[0045] Step 1: Preprocessing the floor plan provided by the user;

[0046] Step 2: Obtain the coordinates of the two ends of the centerline of the wall and the data of the thickness of the wall;

[0047] Step 3: Cutting the doors, windows and balconies in specific areas;

[0048] Step 4: Feature matching and recognition, obtain the feature type and the coordinates of the starting and ending ends;

[0049] Step 5: Whether to re-edit the identification data according to the user's requirements;

[0050] Step 6: 3D reconstruction of the floor plan, displaying from multiple angles and directions.

[0051] Described step one pretreatment method comprises the following steps:

[0052] 11) Grayscale processing is performed on the data after copying the original image data;

[0053] 12) Binarize the grayscale data;

[0054] 13) Expand the im...

Abstract

The present invention relates to the technical field of image recognition, in particular to a parameterized and re-editable modeling method for house type diagrams; specifically, it includes the following steps: preprocessing the house type diagrams provided by users; Thickness data; cutting processing for doors, windows, and balconies in specific areas; feature matching and recognition, obtaining feature types and coordinates of both ends of the start; whether to re-edit the recognition data according to user requirements; display in azimuth; the parametric re-editable modeling method of the floor plan of the present invention is a complete identification method for the basic features of the floor plan, such as: walls, doors, windows, balconies, etc., and supports the re-editing function of each feature, and the user can Change the feature type, material, and size at will to make the final display effect more comprehensive and more in line with the actual needs of users.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a parameterized and re-editable modeling method for a floor plan. Background technique [0002] The parameterized and re-editable modeling method of floor plans can be applied to standard browsers and mobile terminals. It is based on image recognition technology to parameterize the features of walls, doors, windows, balconies, etc. Or the mobile terminal can edit the parameters to create a three-dimensional display model, which supports multi-angle viewing of the three-dimensional effect of the house type. [0003] The existing house-type map recognition technology or method does not have a complete recognition method for the basic characteristics of the house type, such as: walls, doors, windows, balconies, etc., resulting in a lack of a large amount of foundation for the final display effect, and the display effect is not good. good. In addition, some feature vector...
