An enhanced imaging module is disposed on the vehicle, which assists the imaging unit (route reconnaissance module 1) and the feature recognition module 2 to pickup aerial images interrupt free and from a wide angle.

The route reconnaissance module responds to the reconnaissance instructions, which enables the vehicle to patrol the house along a preset flight route. The preset flight route may be achieved by a laser reconnaissance device while the unmanned aerial vehicle flying, wherein the reconnaissance information on the position of objects is formed based on the time difference between the transmitting and the feedback of the signals; the reconnaissance information is transmitted to the control module 3 which constructs a map of the flight environment; a route is planned according to the map as the preset flight route. The preset flight route is also able to be achieved by recording the flight tracks while the manual flight control. The preset flight route is for controlling the heading of the flight. Multiple markers which are able to be identified by the route reconnaissance module are placed in the house to be the route spot guide. The laser reconnaissance device automatically matches the detected markers with the marks on the saved environment map and calculates the current coordinates to position the vehicle. The vehicle is also able to be positioned by a GPS (Global Positioning System) module or an optical flow camera module. The control module 3 generates the reconnaissance instructions according to the external reconnaissance control signals. The external reconnaissance control signals are in various forms according to the demands of the customers, such as voice, password, fingerprint, screen interaction and etc. Corresponding modules are able to be disposed on the vehicle to receive the signals in various forms

The feature recognition module 2 is for recognizing the family members, identifying different features of the family members, such as acts or voices, generating corresponding instruction according to different features of the family members, and recording all the instructions of one family member as an instruction set. Instruction sets are recorded for and one-to-one correspond to different family members. The feature recognition module calculates the repeat frequency of different instructions in the instruction set and forms the control signals for actions of the vehicle toward the family members according to the repeat frequency. For example, the most frequently repeated instructions in the instruction set are selected as the habit and preference features of the family member, according to which the control signals for action of the vehicle toward the family members are generated.
