A kind of bat alignment system and method based on TMS navigationTechnical field
The invention is related to navigation equipment positioning field, more particularly to a kind of bat alignment system based on TMS navigationAnd method.
Background technology
TMS navigation equipments carry out sterically defined mode to determine the bat of TMS using 4 points mostly on the market at presentPosition；Also need to extraly make reference using a correcting plate in position fixing process, by correcting plate, and correcting plate makes firstJust again also without except non-replaceable TMS equipment after；In the operating process, it is also necessary to which another person assists from side.CauseAnd greatly reduce the service efficiency and personnel's efficiency of device.
And a kind of bat localization method based on TMS navigation that the invention is provided wherein utilizes TMS navigation equipmentsThe navigation camera multi-angle itself carried takes pictures bat, passes through pinhole imaging system or convex lens by modern cameraTechnology is realized and taken pictures, and is calculated bat to the distance of each position camera, is realized the positioning carried out to bat spatially.
The content of the invention
For above-mentioned shortcoming of the prior art, navigated it is an object of the present invention to one kind based on TMSBat alignment system and method, its can need not by correction version can be achieved with to bat carry out space orientation.
The above-mentioned purpose of the invention is achieved by the following technical programs.
One aspect of the present invention provides a kind of bat alignment system based on TMS navigation, including：Navigate camera and bat；The navigation camera, for shooting bat.
Preferably, the navigation camera is provided with four, and four navigation cameras are not in same plane.
Preferably, the locus of the navigation camera is set on a predetermined position.
Preferably, the navigation camera is arranged on bat surrounding.
On the other hand the invention additionally provides a kind of bat localization method based on TMS navigation, including：
S1. multi-angled shooting bat image；
S2. the length of bat on image is recorded；
S3. the distance of bat and each navigation camera is calculated；
S4. the locus according to residing for the distance of bat and each navigation camera determines bat.
Preferably, as shown in Figure 3 and Figure 4, the upper and lower ends of bat and the optical center of shooting camera lens form big triangle,Bat form small triangle into upper and lower ends and the optical center of image, the big triangle and small triangle are similar triangles,Therefore the distance x that bat and the camera that navigates are calculated in the S3 is specifically included：
X=nH/h
Wherein h is the length of bat on image, and H is bat physical length, and n is navigation camera camera optical center to navigation phaseThe distance of photo-sensitive cell in machine.
Compared with prior art, the beneficial effect for the technical solution that the invention provides is：One kind is provided to be based onThe bat alignment system and method for TMS navigation, it can utilize the original navigation camera of TMS navigation equipments, be led by multipointNavigate shooting photo of the camera to bat multi-angle, bat is drawn to the distance of each navigation camera, so as to obtain residing for batLocus.

Embodiment
With reference to embodiments and the invention is described in detail in attached drawing.Wherein, being given for example only property of attached drawingIllustrate, expression is only schematic diagram, rather than pictorial diagram, it is impossible to is interpreted as the limitation to this patent；In order to which this hair is better describedThe embodiment of bright creation, some components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；To abilityFor field technique personnel, some known features and its explanation may be omitted and will be understood by attached drawing.
Present embodiment provides a kind of bat alignment system based on TMS navigation, as shown in Figure 1, including：Navigation phaseMachine and bat；The navigation camera, for shooting bat.
The navigation camera is provided with four, and four navigation cameras are not in same plane, is four shown in Fig. 1A navigation camera is evenly distributed in around navigation camera.
The locus of the navigation camera is set on a predetermined position, and the locus of the navigation camera is arranged onKnow on predeterminated position.
The invention additionally provides a kind of bat localization method based on TMS navigation, as shown in Fig. 2, including：
S1. multi-angled shooting bat image；
S2. the length of bat on image is recorded；
S3. the distance of bat and each navigation camera is calculated；
S4. the locus according to residing for the distance of bat and each navigation camera determines bat.
As shown in Figure 3 and Figure 4, the upper and lower ends of bat and the optical center of shooting camera lens form big triangle, bat instituteUpper and lower ends into image form small triangle with optical center, and the big triangle and small triangle are similar triangles, therefore describedThe distance x that bat and the camera that navigates are calculated in S3 is specifically included：
X=nH/h
Wherein h is the length of bat on image, and H is bat physical length, and n is navigation camera camera optical center to navigation phaseThe distance of photo-sensitive cell in machine.
Since the locus for the camera that navigates is default known location, therefore with four not in the navigation phase of approximately the same planeThe distance of machine can determine that the locus where bat.
Calibration：The length of n is adjusted, therefore h is changed correspondingly, and, by the numerical value of more measurement x of x=nH/h, is reduced and is missed from newlyDifference.
When providing a kind of bat alignment system and method based on TMS navigation described in the invention, it can pass throughSpeech recognition device identification foreign student's Chinese is spoken, and generation similarity is judged, so that judge the Chinese spoken language proficiency of foreign student,And foreign student's essential information is carried out by classification storage by Chinese spoken language proficiency, easy to screening of subsequently recruiting student.
Obviously, above-described embodiment of the invention is used for the purpose of clearly demonstrating the invention example,And it is not the restriction to the embodiment of the invention.For those of ordinary skill in the field, stated upperIt can also be made other variations or changes in different ways on the basis of bright, there is no need and unable to give all embodimentsWith exhaustion.All all any modification, equivalent and improvement made within the spirit and spirit of the invention etc., should allWithin the invention scope of the claims.
