Problems solved by technology

However, judging the squareness of the house type by observing the house type map with the naked eye can only be qualitative but not quantitative, and the degree of squareness of the two house type maps cannot be described quantitatively, and the degree of squareness between different house

Abstract

The invention provides a quantitative-evaluation method and device of a house type squareness degree. The method comprises: extracting house outer-wall contours from a house type graph of a to-be-tested house, and acquiring coordinate information of the house outer-wall contours; completing the house outer-wall contours to form a rectangle, and acquiring coordinate information of the rectangle; segmenting the rectangle into nine-square grids, and carrying out labeling of orientation information for each grid in the nine-square grids to form nine orientation grids; calculating the proportion ofa vacant area in each orientation grid according to the coordinate information of the house outer-wall contours and the coordinate information of the rectangle; and scoring a house type squareness degree of the to-be-tested house according to the proportion of the vacant area in each orientation grid. According to the method of the invention, quantitative evaluation of the house type squareness degree is realized, quantitative comparison of squareness degrees can be carried out among different house types, and subjectivity of artificial judgment is avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a method and device for quantitatively evaluating the squareness of house types. Background technique [0002] With the popularization and extensive development of random computer technology, people can obtain housing information more conveniently and quickly. Currently, on the real estate transaction platform, each house will be linked with a corresponding floor plan. Since the floor plan describes the overall attributes of the house, from On the floor plan, you can intuitively see the layout, planning, orientation and area size of the entire house. [0003] Founder-style houses have many advantages compared to irregular-shaped houses. The current method of judging whether a house is square or not is mostly to judge whether a house is square by looking at the house plan with the naked eye. However, judging the squareness of the house type by observing the hou...
