Background
With the continuous development of city scale, the demands of house finding, house renting and house using in cities are continuously increased, and in order to provide better service for users, a house management intermediary provides a house source recommending system for the users to assist the users in selecting house sources; however, the remote floor display system according to the prior art uses sample rooms for display, and the number of the sample rooms is limited due to the cost, so that the whole floor cannot be displayed. The display system needs to arrange a camera in each house between sample plates, and more cameras are needed. Finally, because the shooting range of the cameras in each house is fixed, the participation of the house keeper is not strong, which is not beneficial to exciting the house purchasing enthusiasm of the house keeper, if the consulting clients are too many or the intermediary is busy, the consulting clients cannot pull to lead each client to different houses to watch the actual houses, so that the auxiliary recommendation device which can assist the intermediary in leading the user to watch the house needs to be developed.
Through mass search of the team, the existing house source recommending devices are mainly disclosed as KR1020170014530A, JP2016015162A and CN107030705B, wherein the house watching system disclosed as CN107030705B is particularly representative, and after a VR is selected to watch a house, the system can call a VR database and a program recorded in advance to interact with a house buyer. When the remote robot is selected to look at the house, the salesperson places the robot for looking at the house in the house which the room buyer wants to look at, and the room buyer or the salesperson controls the robot for looking at to move in the house model through the control unit, so that the room buyer can really know the condition of the house to be bought. Because the cost of the house model is far less than that of the sample house, the house model of various house types of the actual floor to be sold can be manufactured, and the choices of house purchasers can be enriched. However, this method is still not as easy to understand the details of the house and the feeling of housing as the user can observe the house on the spot, and requires the user and the salesperson to control the operation robot, which is complicated and inconvenient to operate.
