The angle of whole radar equipment.
Optionally, ball-shaped camera and radar equipment are distributed in mounting bracket in upper and lower.
Under normal conditions, radar equipment 2 needs to monitor illegitimate target, and ball-shaped camera 1 needs to carry out tracking bat to target
It takes the photograph, therefore, ball-shaped camera 1 is usually erected to the top of radar equipment 2.
Direct-connected, the direct-connected side between ball-shaped camera and radar equipment can be communicated between ball-shaped camera and radar equipment
Formula, can be direct-connected using bus, can also set radar equipment and ball-shaped camera under the same wireless network environment, energy
Enough realize that the data between radar equipment and ball-shaped camera direct transfer.
Optionally, mounting bracket 3 can be installed on ground.
Certainly, mounting bracket 2 can also be installed on mounting platform of some fixations, such as the balcony of building construction etc..By
It is generally used to be monitored the pedestrian target of forcible entry in radar equipment 2, goes out pedestrian target in order to accurate measurements, lead to
Mounting bracket 3 is often installed on ground.
Since the height of pedestrian target is generally not above 2 meters, optionally, radar equipment 2 can be erected at from
Ball-shaped camera 1 is erected at liftoff high 3 meters of position by high 2 meters of the position in ground.
Certainly, the antenna height of radar equipment 2 can be 2 meters or so, guarantee to monitor pedestrian target, ball-type is taken the photograph
The antenna height of camera 1 can be 3 meters or so, guarantee to accurately track target.
It optionally, as shown in figure 4, can be direct-connected by RS485 bus 4 between ball-shaped camera 1 and radar equipment 2.
It can be direct transferred, be may be set to be same by the direct-connected realization data of bus between ball-shaped camera and radar equipment
Realize that data direct transfer by wireless network under wireless network environment.In order to avoid external interference is to the data of the border guard system
Interactive influence, it is preferred that direct-connected by bus is set as between ball-shaped camera and radar equipment, selected bus can be
RS485 bus, RS232 bus etc..Since RS485 bus has stronger anti-interference ability, it is therefore preferable that RS485 bus is straight
Even.
Direct-connected using RS485 bus between radar equipment and ball-shaped camera, therefore, radar equipment and ball-shaped camera are logical
It crosses the radar data frame based on RS485 communication protocol made to be communicated, the data format of radar data frame such as Fig. 5 institute
Show.
The length of radar data frame is 100 bytes；Number of targets accounts for a byte, indicates the target that radar equipment detects
Number, maximum value 15；Y-axis distance is actual range unit (rice), accounts for two bytes, data without sign, low byte preceding,
For high byte rear, range is 0~65535, and resolution ratio is 0.1 meter, and the maximum distance of expression is 6553.5 meters, such as 1000 indicate
Distance is 100 meters；X-axis distance is actual range unit (rice), accounts for two bytes, signed number evidence, low byte is in preceding, high byte
Rear, range is -32767~32767, and resolution ratio is 0.1 meter, the point centered on radar equipment, and the value in left side is negative value, right side
For positive value, the maximum distance of expression is -3276.7 meters to 3276.7 meters, such as 123 indicate 12.3 meters, -56 on the right side of radar equipment
5.6 meters are indicated on the left of radar equipment.If without target, the mesh such as Y-axis distance, X-axis distance in the investigative range of radar equipment
Marking data is 0.
Radar data frame is sent to ball-shaped camera in real time by RS485 bus by radar equipment, and sending frequency can be with
Setting, generally can be set as 200 milliseconds of transmission primary radar data frames.Ball-shaped camera after receiving radar data frame,
The number X-axis distance corresponding with target for parsing the target that radar equipment detects according to the data format of radar data frame
With Y-axis range data.Since ball-shaped camera can only track a target in synchronization, ball-shaped camera is tracking
When, it can be tracked with the nearest target of selected distance radar equipment.
Ball-shaped camera is stored with the radar equipment demarcated in advance to the coordinate transformation relation of the ball-shaped camera, specifically
, when being demarcated, one can be arranged in the investigative range of radar equipment using current more popular calibration mode
The target of a static state controls ball-shaped camera PTZ at this time (Pan/Tilt/Zoom horizontally rotates/vertical rotation/zoom)
Movement, the target for monitoring radar equipment, ball-shaped camera shooting picture centre and be of moderate size, record radar
The coordinate information for the target that equipment monitoring arrives and the PTZ coordinate information of ball-shaped camera, can be built based on the two coordinate informations
Coordinate transformation relation of the vertical radar equipment to ball-shaped camera.In order to which the coordinate transformation relation of foundation is more accurate, can move
Target, more calibration are several times.When calibration, the target of radar equipment monitoring and the relationship of border guard system are as shown in Figure 6.
Coordinate transformation relation mainly passes through horizontal offset, vertical offset and distance and the multiplying power of zoom is embodied.
The effect of horizontal offset and vertical offset is to eliminate ball-shaped camera and the angle of radar equipment coordinate system to influence；Distance with
The effect of the multiplying power of zoom is that the size for making target be in picture remains constant during tracking.
Specifically, the multiplying power of horizontal offset, vertical offset and distance and zoom can be by shown in Fig. 7 a and Fig. 7 b
Mathematical model be calculated, wherein Fig. 7 a is that border guard system monitors that the front view of target, Fig. 7 b are boundary defence system
System monitors the top view of target.O coordinate is the position of radar equipment and ball-shaped camera；Q coordinate points are radar equipment monitoring
The target position arrived；(x, y) is the coordinate value for the target that radar equipment monitors, known to parsing from radar data frame
Parameter value；Ball-shaped camera horizontal coordinate, ball-shaped camera vertical coordinate, ball-shaped camera zoom value are current ball-shaped camera
Motion parameter, be known parameters value.It is possible thereby to be calculated:
A=P+ α, wherein A is horizontal offset, and P is ball-shaped camera horizontal coordinate, α=atan2 (y, x) * 180* π；
B=T- β, wherein B is vertical offset, and T is ball-shaped camera vertical coordinate,
H is the antenna height of ball-shaped camera；
C=D/Z, wherein C is the multiplying power of distance and zoom, and D is spherical camera range-to-go,
Z is ball-shaped camera zoom value.
After calibration is completed to obtain the multiplying power of horizontal offset, vertical offset and distance and zoom, that is, establish radar
Coordinate transformation relation of the equipment to ball-shaped camera.After radar equipment monitors to occur the target of illegal act, by target
Coordinate information is sent to ball-shaped camera, and ball-shaped camera is based on the coordinate transformation relation demarcated in advance, available PTZ value,
Ball-shaped camera can move to the corresponding position of PTZ value, to realize the purpose of real-time tracking target.
The above is only the preferred embodiment of the utility model only, is not intended to limit the protection model of the utility model
It encloses.Any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, are all contained in this reality
With in novel protection scope.
