In actual operation, the reference point of the electronic device may also be set by the user, for example, the user may set the reference point of the electronic device as the position of the center point of a certain camera of the electronic device. In this embodiment, the specific form of the reference point of the electronic device is not limited at all.
In this embodiment, the electronic device is provided with a single camera, and the electronic device obtains the distance Li, i being 1, 2 … N between the reference point of the electronic device and the N corner of the living room by using the principle of single-camera ranging. For example, in actual operation, the user may input the height of the user and the shooting posture into the electronic device in advance, so that the electronic device can estimate the height of the current camera from the ground. Then, the user controls the electronic device to shoot each corner of the room through the camera, so that the electronic device can calculate the distance Li between the reference point of the electronic device and each corner of the room.

In this embodiment, the electronic device is further provided with a geomagnetic sensor and a gravity sensor. When the electronic equipment obtains the distance Li between the reference point of the electronic equipment and the N wall feet of a room through a single-camera ranging principle, the current longitude and latitude values Ai of the electronic equipment are measured by using a geomagnetic sensor, and the measured Ai is recorded. And the electronic equipment also acquires the value of the gravity acceleration Zi axis of the electronic equipment by using a gravity sensor, so as to acquire the included angle alpha i between the electronic equipment and the vertical plane. The gravity acceleration Z axis of the electronic equipment is vertical to the plane where the display screen of the electronic equipment is located, and the acceleration g of the free falling body is on the vertical plane, so sin α i is Zi/g; α i ═ arcsin (Zi/g).
And step 102, acquiring the side lengths of the rooms according to Li, Ai and alpha i.
In this embodiment, taking N as an example and 3, the electronic device will be described as obtaining each side length of a living room from Li, Ai, and α i:

β2＝abs(A2-A3)；
and acquiring an included angle beta 3 between M1 and M3 according to the warp and weft values A1 and A3:
β3＝abs(A1-A3)；
since M1, M2, and M3 are known, the angles β 1, β 2, and β 3 between M1, M2, and M3 are also known. Therefore, the electronic device may calculate and obtain the first side length H1 of the living room according to the formula H1 ═ M1+ M2-2M1 ═ M2 ═ cos β 1; and calculating and acquiring a second side length H2 of the living room according to a formula H22-M22 + M32-2M 2M3 cos beta 2; and calculating and acquiring a third side length H3 of the living room according to a formula H32-M32 + M12-2M 3-M1-cos beta 3. Wherein H1 is the side length DE; h2 is side length EF; h3 is the side length DF.
