Description
Technical field
The invention belongs to more videos in video fusion technical field more particularly to a kind of distributed video emerging system to melt
Close the control device of equipment.
Background technology
With network technology, the development of computer processing technology, higher resolution, bigger picture video enjoy great popularity,
This is because higher resolution ratio is capable of providing more video content details, it is on the spot in person that the picture of bigger can bring user
Appreciation effect, be seemingly in entire picture the same.
In order to reach the picture dimension of bigger, clearer image quality and more bright projected picture, people for
Projecting apparatus shows that the performance requirement of screen is higher and higher, but plurality of devices existing on the market is all extremely difficult to people now
The performance indicator needed, so projection integration technology is come into being, it is a kind of multimedia technology, is nowadays a kind of be directed to projects
The new technology that the development of technology is come into being, in commercial propaganda, large-scale museum, video conference, large size 3D developments of games, military mould
Intend training aspect to suffer from being widely applied.
Two kinds of structures can be used in usual Multisensor video fusion system, the first is set using the very high video fusion of separate unit performance
It is standby, while multiple pictures are exported, the benefit of the structure is easy to control, but the expansion also for whole system from now on makes band simultaneously
Difficulty is carried out；Second is to use the general video fusion equipment collaboration completion video fusion task of more performances, more in this way
Between video fusion equipment can mutually independent work, whole system has good expansibility, but more videos melt
How to cooperate between conjunction equipment is more scabrous problem.
For second of structure, inherently there is timess for much needing multiple devices while completing for Multisensor video fusion system
Business, such as：The geometric correction of overlapping region, is played simultaneously Fusion Edges.In task listed above, lack any
The participation of one equipment cannot all reach expected result of broadcast.In addition, due to the presence of more video fusion equipment, for field
Also there is the high demand of comparison on ground, that is, needs sufficiently large place to accommodate entire Multisensor video fusion system.
To sum up, there is a series of problems for Multisensor video fusion system of the prior art, and what video fusion needs played regards
Frequency division resolution is constantly promoted, and the fusion treatment data volume brought also constantly is rising, due to the calculating energy of separate unit fusion device
Power is limited, shows that the ability of equipment is also limited, so needing to show equipment come common using more video fusion equipment and Duo Tai
Complete video fusion task.But there are problems that being difficult to co-ordination between each video fusion equipment again, it is of the invention with regard to how
Multiple video fusion equipment is controlled to carry out collaborative work and propose solution.
