Here, a structured light camera or a visible light camera may be required to acquire a house source image in a smaller number (e.g., 20) of acquisition directions.
In some scenarios, a person may go to the site of the house source, take a picture in the field, and one or more image acquisition points may be provided in each room of the house source. At each acquisition point, house source pictures can be acquired at a plurality of different angles, then a three-dimensional model of the acquisition point is established according to the acquired house source pictures, and the three-dimensional house source model can be generated by utilizing the three-dimensional model of each acquisition point.
At each acquisition point, the target acquisition apparatus may be placed to a means for placing the target acquisition apparatus (i.e. the execution body described above). The execution body may execute step 101.

For example, if the target acquisition apparatus is implemented based on a laser radar or a millimeter wave radar, the above-described execution subject control target acquisition apparatus is required to acquire a house source image.
For example, if the image capturing apparatus is implemented based on a visible light sensor, the execution subject may control the target capturing apparatus to capture the house source image, or the user may manually control the target capturing apparatus to capture the house source image.
Here, the user setting may indicate whether the execution subject control target acquisition device is required to acquire the house source information.
In some scenarios, the target acquisition device may acquire the room source image in response to receiving an acquisition instruction.
Alternatively, the acquisition instructions may be issued by the user. The user may issue an image acquisition instruction (e.g., trigger a displayed graphical acquisition control) when the acquisition direction and the preset acquisition angle satisfy the preset conditions. Then, the target acquisition device can respond to the acquisition instruction of the user to acquire house source information.
Alternatively, the collection instruction may be automatically issued by the execution body. The execution main body can detect whether the motion trail of the target acquisition equipment is in place, generate an acquisition instruction if the motion trail is in place, and not generate the acquisition instruction if the motion trail is not in place.
Therefore, for different acquisition equipment, the acquisition mode (manual or machine automatic control acquisition) suitable for the acquisition equipment can be determined, and the acquisition efficiency and accuracy are improved.
In some embodiments, the method further comprises presenting a hint information in response to determining not to control the target acquisition device to acquire room source information and in response to detecting that the acquisition direction of the target acquisition device is consistent with a preset acquisition angle.
The prompt information is used for prompting the target acquisition equipment to enter a predefined acquisition preparation state, and the target acquisition equipment acquires house source information according to an acquisition instruction of a user.
Therefore, if the information collection is determined to be carried out by manually controlling the target collection device, prompt information can be sent to a user after the target collection device moves in place on the movement track, so that the user is prompted to carry out information collection.
In some scenarios, the user may also fine tune the target acquisition device according to his own judgment after prompting the information.
In some embodiments, the method further comprises controlling the target acquisition device to acquire the room source information when the acquisition direction is consistent with a preset acquisition angle in response to determining to control the target acquisition device to acquire the room source information.
Here, if it is determined that the target acquisition device is controlled by the execution subject to acquire the room source information, the execution subject may send an acquisition signal to the target acquisition device when the target acquisition device is at all times in an acquisition direction and a preset acquisition angle, and the target acquisition device may perform the room source information acquisition if it receives the acquisition signal.
