House map parameterization and re-editing modeling method

Abstract

The present invention relates to the technical field of image recognition, and more particularly to a house map parameterization and re-editing modeling method. The method comprises the following steps: preprocessing a house map provided by a user; obtaining coordinates of two points of the beginning and the end of the center line of the wall and wall thickness data; carrying out cutting processing on the specific area of the door, the window, and the balcony; carrying out feature matching recognition to obtain a feature type and the coordinates of two points of the beginning and the end; according to user requirements, determining whether carrying out re-editing processing on recognition data; and carrying out three-dimensional reconstruction of the house map, and displaying the house map in a multi-angle and multi-dimension manner. The house map parameterization and re-editing modeling method provided by the present invention is a complete recognition method for basic features such as the wall, the door, the window, the balcony and so on of the house, and the re-editing function of each feature is supported; and the user can change the feature type, the material, and the size at will, so that the final display effect is more comprehensive, and actual requirements of the user are more in line with.

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...

[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.
