Specific implementation mode
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation describes, it is clear that described embodiment is only a part of the embodiment of the application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
As shown in Figure 1, the application scanning imagery control method first embodiment includes：
S11：Control scanning antenna is scanned imaging to scanned target.
The application scanning imagery control method is mainly used in rays safety detection apparatus, such as millimeter wave human body safety check instrument.Wherein, it sweeps
It can be to the array antenna of scanned target transmitting millimeter wave (such as THz wave) to retouch antenna, can also be other kinds of day
Line is not specifically limited herein.
Scanned target can be human body, can also be other objects, such as luggage case etc..Since human body is in scanning process
The possibility bigger of middle movement is illustrated by taking human body as an example in the present embodiment and subsequent embodiment.
Specifically, in an application examples, after scanned target enters safety check instrument, server end or control terminal can open
Scanning process, control scanning antenna emit millimeter wave to scanned target, and receive the millimeter wave of scanned target reflection, then
Server end will be passed on the millimeter-wave signal of the reflection back or control terminal carries out imaging.During this scanning imagery, by
It is that edge emitting side receives in scanning antenna, then uploads, therefore, if scanned target movement during this, such as arm pendulum
It moves, then can influence imaging results, the image arm position ultimately generated can be smudgy.It is carried out according to the blurred picture different
Analyte detection then may greatly cause to judge by accident.
S12：Judge scanned target whether remains stationary.
If judging result is no, S13 is thened follow the steps.
S13：Interrupt the scanning imagery of scanned target.
Cause to be ultimately imaged smudgy problem, this reality for the scanned target movement being likely to occur in scanning process
Example is applied during scanning imagery, judging scanned target whether by way of remains stationary, is moved in scanned target, i.e.,
When in nonstatic state, direct interrupt scanning imaging process, to avoid being judged by accident caused by generation blurred picture, Jin Erke
To reduce the rate of false alarm of rays safety detection apparatus, while the invalid scanning imagery time is reduced, improves efficiency.
Specifically, in the above application examples, sensing can be set at human body parts keypoint part, such as important artis
Device, the location information of human body keypoint part during acquisition scans, by judging that the position of the keypoint part in scanning process is
It is no to move, if moving, it can determine that the scanned target is in nonstatic state, step can be executed herein
S13 interrupts the scanning imagery of scanned target.And if the equal remains stationary of scanned target during scanning imagery, simultaneously
Do not influence the normal workflow of the safety check instrument, i.e., the safety check instrument can continue to execute step S14, to scanned target carry out at
Foreign matter is identified as processing, and according to imaging results.Certainly, it in other application example, can also be utilized by Kinect somatosensory device
Kinect joint models track the position coordinates of the multiple artis of human body simultaneously, can also use other judgement sides such as visual identity
Formula is not specifically limited herein.

Further include：
S15：Information warning is sent out, to prompt scanned target to move, needs to rescan.
Wherein, which can be voice prompt, can also be text prompt, can also be light prompt, and or
Person is the combination of above-mentioned prompting mode, is not specifically limited herein.
Specifically, in an application examples, when judgement is moved by scanning staff, which can sound the alarm,
And use text prompt scanned target to move simultaneously, it needs to rescan.If needing to rescan at this point, security staff confirms,
It can then remind by scanning staff's remains stationary, restart to scan.Certainly, in other application example, voice can also only be used
Or text prompt is only used, or using light prompt etc..
In other embodiments, judge whether remains stationary can be obtained once scanned target by certain interval of time
The key position coordinate of scanned target is judged.
Specifically as shown in Fig. 2, the application scanning imagery control method second embodiment is controlled in the application scanning imagery
On the basis of method first embodiment, further limiting step S12 includes：
S121：The coordinate of the artis of scanned target is obtained every preset time；
Wherein, which is the pre-set interval time for obtaining scanned target partial joint point coordinates, should
Preset time is less than the scanning imagery time of scanned target.For example, when the scanning imagery time of scanned target is 2 seconds, it should
Preset time could be provided as 100 milliseconds.
The artis of the scanned target can be it is pre-set can embody scanned human body whether move it is important
Node.For example, the artis such as knee joint, wrist, shoulder.The coordinate of the artis of the scanned target is three-dimensional coordinate, can be with
It is obtained by devices such as sensors.

Position is consistent, such as be centimetre etc..
Specifically, in an application examples, judge whether is gap between the adjacent coordinate obtained twice of identical artis
When more than range of allowable error, it can calculate first between the coordinate and the preceding coordinate once obtained that each artis currently obtains
Distance, then judge the distance whether be more than 0.5 coordinate unit, if the above-mentioned distance of all artis is no more than 0.5
A coordinate unit then repeats above-mentioned steps after obtaining coordinate next time, until the scanning imagery of current scanned target
Process terminates, if there are the distance between adjacent coordinates obtained twice of any one artis to be more than 0.5 during this
Coordinate unit then judges that gap between the adjacent coordinate obtained twice of identical artis is more than range of allowable error, then can be with
The step of continuing to execute subsequent interrupt scanned target scanning imagery process.If the adjacent of all artis is obtained twice during this
The distance between coordinate taken whether no more than 0.5 coordinate unit, then judge the adjacent seat obtained twice of identical artis
For gap between mark no more than range of allowable error, which can be with normal imaging, and executes follow-up foreign matter identification process.
Optionally, it after judgement scanned target does not have remains stationary, can also be carried by modes such as voice and/or words
Show that being scanned human body in scanning process does not have remains stationary, needs to rescan, and scanned human body can be prompted according to pre-
Determine posture keep stand a period of time it is motionless, such as joint model shown in Fig. 4 stance keep stand 2 seconds it is motionless.
In the present embodiment, imaging is scanned to scanned target by controlling scanning antenna, and in scanning imagery process
Whether the middle gap judged between the adjacent coordinate obtained twice of the artis of scanned target is more than range of allowable error, to sentence
Disconnected scanned target whether remains stationary, and when the judgment result is No interrupt scanned target scanning imagery, so as to
In scanned target nonstatic, interrupt scanning imaging process avoids judging by accident caused by generation blurred picture, and then can subtract
The rate of false alarm of few rays safety detection apparatus, while invalid imaging time can be reduced, it realizes simply, conveniently, and do not influence safety check instrument just
