Embodiment Construction
[0077] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.
[0078] like figure 1 As shown, the method for automatically identifying walls in the house type diagram disclosed by the present invention includes the following steps:
[0079] Step 1, analyze the location of the interference information in the floor plan, and then use the largest outer contour of the wall to eliminate the interference information in the floor plan;
[0080] Step 2, set the segmentation threshold according to the bimodal feature of the grayscale histogram of the wall in the floor plan, segment the wall area from the grayscale floor plan according to the segmentation threshold, and filter the interference items according to the size of the connected domain area;
[0081] In step 3, the vector data structure of the wall is generated by dir...

The invention provides a method for automatically identifying a wall body in a house type graph, which comprises the following steps of: carrying out position analysis on interference information in the house type graph, and eliminating the interference information in the house type graph by utilizing the maximum outer contour of the wall body; setting a segmentation threshold value according to bimodal characteristics of a wall gray histogram in the house type image, segmenting a wall area from the gray scale house type image according to the segmentation threshold value, and filtering an interference item according to the size of a connected domain area; and generating a vector data structure of the wall in a directional straight line fitting manner, so that the wall is identified from the house type graph. According to the method for automatically identifying the wall body in the house type graph, in the house type graph preprocessing stage, removal processing on interference information in the house type graph is added, the difficulty of follow-up wall recognition is reduced, and the accuracy of wall recognition is improved; the improved histogram double-peak method is utilizedto segment the wall body, and the situation of uneven gray scale caused by edge information damage is considered during threshold value selection, so that the wall body and the background can be distinguished better.
Description
technical field [0001] The invention relates to a method for identifying a house type diagram, in particular to a method for automatically recognizing a wall in a house type diagram. Background technique [0002] With the change of modern people's demand for house purchase and decoration, people increasingly hope to know the overall structure of the house and the expected decoration effect in advance. However, the traditional two types of building plans, building floor plans and building construction drawings, cannot bring users an immersive experience. At present, a new architectural effect display method based on virtual reality technology, three-dimensional house type display technology, has gradually replaced the traditional two-dimensional house type map and appeared in the house purchase market. [0003] Since the simple two-dimensional floor plan cannot provide the information of the entire building, it cannot bring realistic visual effects, and it is more complicate...
