The invention relates to an AR-based house type graph three-dimensional display method, medium, apparatus and device. The method comprises the following steps of obtaining an initial house type picture containing a house type picture, and carrying out perspective correction processing on the initial house type picture to generate a target house type picture; extracting the wall body data and doorand window data of the house type image in the target house type image, and constructing an original three-dimensional model corresponding to the house type image in real time according to the wall body data and the door and window data; and calling a preset AR rendering engine to display an original three-dimensional model according to the first user instruction. According to the method, the house type image can be accurately and automatically identified and corrected through the image processing method, so that the 3D house type model is accurately constructed in real time, and the AR display effect of the house type image is achieved. Through the super strong substitution sense and immersive experience of AR, a user can visually and clearly know the residential structure, meanwhile, theuser can better communicate with the user through interaction and display, so that the requirements of the user are met, the participation sense of the user is increased, the people stream attentionis attracted, and the advertising effect is improved.
