Description
Technical field
The present invention relates to indoor locating system fields, and in particular to a kind of indoor positioning tracking system.
Background technique
UWB location technology is a kind of positioning method of label-base station type, then base station receives the position signal of label
Convey signal to system, but most of UWB location technologies can only realize positioning function, and can not achieve real-time tracking, realize with
Recognition of face can be used in track technology, but this technology cost is too high, does not meet real needs, so UWB location technology has
Its limitation, such as in bar, concert, KTV etc. need to track when leading role pursues stage effect UWB location technology just not
It is logical, stage leading role real-time tracking is realized so being improved on the basis of UWB, it is necessary to.
Summary of the invention
In order to overcome drawbacks described above, it is a primary object of the present invention to design a kind of indoor positioning tracking system.
To achieve the goals above the present invention adopts the following technical scheme:
A kind of indoor positioning tracking system, including position resolves and control server, several base stations, bulb camera, projection
Instrument, the base station, bulb camera, projector all connect with each corresponding units inside position resolving and control server
It connects.
Further, the position resolves and control server includes position calculation unit, control unit, image reception list
Member and video code flow processing unit.
Further, the base station all connects the input terminal of the position calculation unit, and all base stations will receive signal source
Position input position computing unit, the input terminal of the output end connection described control unit of position calculation unit, position calculates single
Member issues instructions to control unit after calculating out position, and the output end of described control unit connects ball machine camera, control unit
Control camera is schemed towards signal source, the input terminal of the ball machine camera connection described image receiving unit after obtaining order
As receiving unit, video image captured by camera is received, the output end of image receiving unit connects at the video code flow
The input terminal of unit is managed, video image is processed into continuous video by code stream, and the output end depending on code stream processing unit connects throwing
Video can be projected on wall by shadow instrument.
Preferably, the quantity of the base station is no less than 4.
Preferably, the algorithm of the position calculation unit is the relatively simple algorithm that default position is arranged: pre-setting and takes the photograph
As the presetting bit of head, when the calculated signal source of position calculation unit is in immediate presetting bit, control camera is adjusted to
The position, the method need to only calculate Position Approximate, although positioning is not accurate, algorithm is simpler.
Preferably, the algorithm of the position calculation unit may be the more complex algorithm according to coordinate tracking: establish
Three-dimensional cartesian coordinate system calculates the horizontal and vertical angle of signal source offset origin, is converted to camera shooting using camera as origin
The angle coordinate of head tracks to control video camera and realize towards signal source, and the method positioning is more accurate, but algorithm comparison is multiple
It is miscellaneous.
The beneficial effects of the present invention are: it joined real-time photography head following function based on UWB indoor positioning technologies, pass through
Position resolves and control server receives the position of signal source and calculated, then to camera issue instruction carry out it is real-time
Tracking, being finally processed into the consecutive image that camera captures by video code flow is that video projects on large screen, this skill
The case where art scheme realizes positioning, Tracking Integrative, needs to track stage leading role suitable for bar, concert, KTV etc..
Detailed description of the invention
Fig. 1 is systematic schematic diagram of the invention.
Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings.:
Embodiment one
A kind of indoor positioning tracking system, including position resolves and control server 1, several base stations 2, bulb camera 3, throwing
Shadow instrument 4, the base station 2, bulb camera 3, projector 4 all with the position resolve and control server 1 inside each phase
Unit is answered to connect.
The position resolve and control server 1 include position calculation unit 5, control unit 6, image receiving unit 7 with
And video code flow processing unit 8.
The base station 2 all connects the input terminal of the position calculation unit 5, and it is defeated that all base stations 2 will receive source location
Enter position calculation unit 5, the input terminal of the output end connection described control unit 6 of position calculation unit 5, position calculation unit 5
Control unit 6 is issued instructions to after calculating out position, the output end of described control unit 6 connects ball machine camera 3, control unit
6, which obtain after order control camera, connects the input terminal of described image receiving unit 7 towards signal source, the ball machine camera 3,
Image receiving unit 7 receives consecutive image acquired in camera, and the output end of image receiving unit 7 connects the video code flow
The input terminal of processing unit 8, consecutive image are processed into video by code stream, and the output end of video code flow processing unit 8, which connects, to be thrown
Video can be projected on wall by shadow instrument 4.
The quantity of the base station 2 is no less than four, which receives label (that is: the signal being worn on performing artist
Source), quantity is more, and positioning is more accurate, but base station cost is high simultaneously, can be made up by using the excellent server of performance parameter
Positioning accuracy.
The algorithm of the position calculation unit is the relatively simple algorithm that default position is arranged: pre-setting the pre- of camera
Set, when the calculated signal source of position calculation unit is in immediate presetting bit, control camera is adjusted to the position, this
Method need to only calculate Position Approximate, and algorithm is simpler.
The present embodiment positioning is relatively coarse, so being suitable for the lesser situations of the interior spaces such as KTV, mini bars.
Embodiment two
With embodiment two the difference is that: the algorithm of the position calculation unit may be according to the more multiple of coordinate tracking
Miscellaneous algorithm: establishing three-dimensional cartesian coordinate system, using camera as origin, calculates the horizontal and vertical angle of signal source offset origin
Degree, is converted to the angle coordinate of camera, tracks to control video camera and realize towards signal source, the positioning of this algorithm is more smart
Really, algorithm comparison is complicated.
The present embodiment accurate positioning, so being suitable for the larger situations in places such as dramshop, concert.
