Emitter arranges at certain intervals.
In the passive indoor positioning device, there are three corner reflectors for one group of corner reflector tool.
In the passive indoor positioning device, the specification of three corner reflectors is respectively in 10dB, 15dB and 20dB
One or more specifications.
In the passive indoor positioning device, the arrangement in horizontal direction of three corner reflectors, two neighboring angle is anti-
Spacing 10cm between emitter.
In the passive indoor positioning device, three corner reflectors are arranged with a particular order, the particular order pair
Answer a coding.
In the passive indoor positioning device, one group of corner reflector is fixed on indoor metope by the frame
Or on pillar.
In the passive indoor positioning device, the one group of height of corner reflector away from ground is 60cm to 70cm.
In the passive indoor positioning device, the corresponding spy of the particular order of three corner reflectors in this group of corner reflector
It delimits the organizational structure code, the position coordinates of metope or pillar that corresponding this group of corner reflector of the specific coding is fixed.
Using in the passive indoor positioning device of the utility model comprising one group of corner reflection being set on the frame
Device；The group has multiple corner reflectors arranged at certain intervals of mutually different specification, so that a spy can be corresponded to
Code of delimiting the organizational structure corresponds to a position coordinates in turn.When the vehicle equipped with millimetre-wave radar emits signal during traveling, by this
Group corner reflector reflects, and relative position and the angle of corner reflector can be calculated according to the signal, and then can be according to one
The actual coordinate of a or multiple such passive indoor positioning devices extrapolates the location of millimetre-wave radar, i.e., locating for vehicle
Position, realize positioning.The passive indoor positioning device of the utility model, does not need to power, easy for installation, not by signal shadow
It rings, effect stability, and low in cost, and because its own is by calibration, positioning accuracy is also higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the passive indoor positioning device of the utility model.
Specific embodiment
In order to be more clearly understood that the technology contents of the utility model, spy lifts following embodiment and is described in detail.
Refering to Figure 1, the structural schematic diagram of the passive indoor positioning device for the utility model.
In one embodiment, which includes frame and one group of angle being set on the frame
Reflector；Each corner reflector has identical or different specification, and arranges at certain intervals.The rule of three corner reflectors
Lattice can be respectively one of 10dB, 15dB and 20dB, two or three of specification.
In more preferably embodiment, the arrangement in horizontal direction of three corner reflectors, two neighboring angle is anti-
Spacing 10cm between emitter.Three corner reflectors are arranged with a particular order, the corresponding coding of the particular order.
For example, the corner reflector number 0 of 10dB indicates, the corner reflector number 1 of 15dB is indicated, the corner reflection of 20dB
Device digital number 2 indicates that each combines corresponding one group of coding.If three corner reflectors of a passive indoor positioning device
Put in order as 15dB, 10dB, 20dB, then its it is corresponding be encoded to (1,0,2), correspondingly, if sequence be 20dB, 15dB,
15dB, then it is corresponding to be encoded to (2,1,1), it sequentially is encoded to (1,0,0) for 15dB, 10dB, 10dB are then corresponding, with such
It pushes away.
In preferred embodiment, one group of corner reflector is fixed on interior away from ground by the frame
Height be 60cm to 70cm metope or pillar on.The particular order of three corner reflectors in this group of corner reflector corresponding one
A specific coding, the position coordinates of metope or pillar that corresponding this group of corner reflector of the specific coding is fixed.
For example, (1,0,2) respective coordinates (x1, y1), (2,1,1) respective coordinates (x2, y2), (1,0,0) respective coordinates
(x3, y3).
In the application of the utility model, by taking underground parking as an example, installed on wall or pillar every a certain distance
There is the positioning device, the specification sequence of the corresponding corner reflector ABC of each device is different, it is assumed that the corner reflection of 10dB
Device number 0 indicates that the corner reflector number 1 of 15dB indicates that the corner reflector digital number 2 of 20dB indicates, each
Combine corresponding one group of coding.If arrangement is three passive indoor positioning devices, No. 1 equipment is corresponding to be encoded to (1,0,2), 2
Number equipment is corresponding is encoded to (2,1,1), and No. 3 equipment are corresponding to be encoded to (1,0,0), the corresponding fixed object of every group of coding
Manage coordinate, such as No. 1 coding respective coordinates (x1, y1), No. 2 coding respective coordinates (x2, y2), No. 3 coding respective coordinates (x3,
y3).When emitting signal during traveling equipped with the vehicle of millimetre-wave radar, reflected by corner reflector, it can basis
The signal calculates the anti-relative position and angle of angle of departure, and software can extrapolate millimetre-wave radar according to the actual coordinate of corner reflector
Location, i.e. the location of vehicle, to realize positioning.
It is understood that in the present invention, the quantity, specification of corner reflector in the passive indoor positioning device,
Positional relationship, the relationship between corresponding coding, the setting of relationship and passive indoor positioning device between coding and coordinate
Position can be adjusted according to the needs of practical application scene.
Using in the passive indoor positioning device of the utility model comprising one group of corner reflection being set on the frame
Device；The group has multiple corner reflectors arranged at certain intervals of mutually different specification, so that a spy can be corresponded to
Code of delimiting the organizational structure corresponds to a position coordinates in turn.When the vehicle equipped with millimetre-wave radar emits signal during traveling, by this
Group corner reflector reflects, and relative position and the angle of corner reflector can be calculated according to the signal, and then can be according to one
The actual coordinate of a or multiple such passive indoor positioning devices extrapolates the location of millimetre-wave radar, i.e., locating for vehicle
Position, realize positioning.The passive indoor positioning device of the utility model, does not need to power, easy for installation, not by signal shadow
