Description
Technical field
Present invention relates particularly to a kind of method that utilization monopod video camera and projector realize virtual window.
Background technology
With science and technology development, various new electronic equipments be applied to people work, life in.Monopod video camera
With projector as video capture equipment and large-scale display output equipment, security protection, meeting, education, family are widely used in
In movie theatre.
It is without landscape or the room that should not be opened a window, unavoidable to constrain and barren.Existing solution can install TV
Deng display device, displaying video programs content.Video camera can also be assembled on the basis of this, show the content that video camera shoots
（Such as monitored picture）.But said method all equally gives spectators without image of Buddha real window（Observer）Real telepresenc is provided.
Such as, observed outside room by real window, visual angle will change with respect to the difference of window position with observer, in difference
Position, it is seen that scenery also difference, as shown in Figure 1.
The content of the invention
The technical problem to be solved is to provide one kind to realize virtual window using monopod video camera and projector
The method at family, can form a virtual window indoors on wall.
The present invention is to solve above-mentioned technical problem by the following technical programs：It is a kind of to utilize monopod video camera and projector

Feed controller, change in location of the controller according to the single people, control monopod video camera real-time adjustment camera lens direction and zoom
Multiplying power, the observation visual angle for simulating the single people are shot, and the scene of shooting is passed to projector in real time, and projector exists
Image of the scene with window frame pattern after superimposed is projected on wall.
Further, whether the environmental data is additionally included in the reconnaissance range of position of human body sensor more personal；
The step 4 also includes herein below：
Controller analysis environments data, judge whether there is more personal in the reconnaissance range of position of human body sensor；If ring
Border data are have more personal in the reconnaissance range of position of human body sensor, then execution step 7；
Step 7：It is main observer that controller specifies the people in many individuals according to default rule, then carries out following behaviour
Make：
A. position of human body sensor obtains the current location of main observer and is sent to controller, and controller is examined according to subjectivity
The current location of person, control monopod video camera adjustment lens direction and zoom ratio are shot to corresponding observation visual angle, together
When virtual window image is presented according to the corresponding shooting visual angle of monopod video camera also；
B. position of human body sensor keeps track the motion of main observer, and will be its current location mobile message constantly anti-
Feed controller, change in location of the controller according to main observer, control monopod video camera real-time adjustment camera lens direction and zoom
Multiplying power, the observation visual angle for simulating main observer are shot, and the scene of shooting is passed to projector in real time, and projector exists
Image of the scene with window frame pattern after superimposed is projected on wall.
Further, the rule in the step 7 is referred to：To move most active artificial main observer；Or distance is pre-
If the nearest artificial main observer in position；Or median is calculated according to many personal distributing positions, with positioned at the middle position
The people of value or apart from the nearest artificial main observer of median.
The beneficial effects of the present invention is：Using monopod video camera and projector, can be with by visual angle is projected on wall
Observer's change in location and the window picture that changes, so as to realize wall transparence.
