Uploading the shot house type picture by a user, uploading a wall drawing system, and adaptively preprocessing the picture information according to the picture information content by the system: scaling the picture, simplifying the color and gray processing to obtain the processed picture information, and finally calculating to obtain a first gray average value of each pixel point.
Further, the input plurality of picture information is picture information of each room in the house type map.
Step S102: determining a first vertex in a preset coordinate grid as a first coordinate point of the wall body, and generating four coordinate points according to first input information to form a first wall body; the first coordinate point of the wall body can be one of an upper left vertex or an upper right vertex of the wall body or other two points, and the first input information comprises direction information, a length value, a thickness value and a height value.
Specifically, in the 2D wall plan view of the canvas, the wall is identified as a line segment having a certain thickness, including four vertices (each vertex corresponds to a corresponding coordinate), and when the wall is ordered, one of the vertices may be selected as a starting point (i.e., a first vertex). The selection may be made according to actual conditions, and is not limited herein.
The length and thickness of the wall body can be determined by moving a mouse, the accurate size is obtained by inputting through a keyboard, and the thickness and attribute of the wall body are switched through keys of the keyboard; meanwhile, the wall body presents a virtual effect, the wall body to be drawn is displayed in advance, and the wall body is materialized after the wall body is confirmed through a mouse.
Step S103: when the indication icon approaches to a certain range of the first wall, the indication icon moves to be close to one side of the first wall, a second coordinate point is determined as a starting point, four coordinate points are generated according to the received second input information, and a second wall is formed; the second input information includes direction information, a length value, a thickness value, and a height value;
step S104: when the distance between the first wall body and the second wall body is within a certain threshold value range, the second wall body automatically moves towards the first wall body, and the first wall body and the second wall body are partially overlapped to form a connecting wall body; wherein the first wall partially overlapping the second wall comprises: the coordinates of the nearest vertexes in the four vertexes of the first wall body and the second wall body coincide; or the two nearest sides of the four sides of the first wall body and the second wall body are attached;
After the first wall is obtained in step S102, when the indication icon approaches the first wall within a certain range, the drawing interface automatically defaults to the indication icon to be close to the first wall, the indication icon can move to be close to one side of the first wall, and various specific setting modes are available and are not repeated here;
When the distance between the first wall body and the second wall body is within a certain threshold range, the second wall body automatically moves towards the first wall body, and the coordinates of the nearest vertexes of the four vertexes of the first wall body and the second wall body coincide;
on the other hand, when the distance between the first wall body and the second wall body is within a certain threshold range, the second wall body automatically moves towards the first wall body, and two nearest edges of the four edges of the first wall body and the second wall body are attached;
After the physical wall body is completed, the continuous wall drawing state can be triggered, and the continuous wall drawing state can be automatically exited by right-clicking a mouse or until a closed room is completed.
Step S105: continuously repeating the steps S103 and S104 to generate a third wall body and a fourth wall body to form a closed room diagram;

Step S109: comparing the first gray average value with the second gray average value, and if the first gray average value and the second gray average value are the same, finishing drawing; otherwise, different pixel points are found out, and the drawn house type graph is modified.
And comparing the obtained first gray average value with the second gray average value by the wall drawing system, judging whether the first gray average value and the second gray average value are the same, if so, considering that the drawing is completely correct, and if not, finding out different pixel points to prompt a drawing person so as to enable the drawing person to know the position to be modified. The method can quickly find out the difference.

In the prior art, a single line drawing tool is combined with a marking tool (CAD), and a painting tool draws one stroke by one stroke; or the multi-line drawing tool is combined with the marking tool, and the method is completed through repeated operation for a plurality of times. The two modes adopt an internal line and middle line drawing method, the external line is ignored, the concentration of multi-information processing is insufficient, more repeated actions are caused, the technical implementation difficulty is higher, and the computer computing resource consumption is more. The prior art has the following technical disadvantages:
