[0033] Please check Figure 1 to Figure 6 , in the prior art, there are many methods for generating a 3D house type model for a 2D house type map, a method of generating a 3D house type model based on a 2D house type photograph taken by a camera according to the present invention, which includes:
[0034] Step 1, take a 2D house type photo through the camera; the 2D house type photo obtained by this camera can be obtained through the camera on the portable mobile device, and the portable mobile device can be any one of a mobile phone, a hand-held camera, or a tablet.
[0035] Step 2: Correct the 2D house type photo obtained in step 1 by the essential matrix restoration method, select the coordinates of the four corners in the image and restore a series of information such as the focal length of the camera, the image shooting angle, and the shooting distance according to the essential matrix restoration method, According to these information, the distortion of the captured 2D i...
