In embodiments of the present invention, control device 140 swashs for ought not receive first in multiple laser pickoffs 121
During the output signal of optical receiver 121, according to the predeterminated position data acquisition first of the first laser receiver 121 prestored
Ordinate of the laser pickoff 121 in preset coordinate system.
It is understood that interactive device 130 is in Laser emission array 110, display device 150 and laser pick-off battle array
During the hollow space that row 120 are formed, control device 140 controls generating laser 111 and laser pickoff 121 to work, interaction
Equipment 130 can stop that an optics in a plurality of optical path that Laser emission array 110 is formed with laser pick-off array 120 leads to
Road, so as to which the laser for preventing the laser pickoff 121 corresponding to the path to launch from receiving generating laser 111 can not be defeated
Go out electric signal to control device 140.And other optical paths are not blocked, so that laser pickoff 121 can receive
The laser of generating laser 111, and electric signal is exported to control device 140.
Therefore, control device 140 can be determined according to the interface for the first laser receiver 121 for not receiving electric signal
The numbering of first laser receiver 121, so as to obtain the column of first laser receiver 121 at a distance of aobvious according to the numbering
The distance of showing device 150.
For example, it is assumed that being classified as first row close to display device 150, n-th is classified as residing for first laser receiver 121
Row, the second predetermined interval are m, and the second default angle is β, then the distance of the distance display device 150 of first laser receiver 121 is
(n*m)*cos(β-90°)。
In addition, if the length of laser pick-off array 120 and Laser emission array 110 is l, then the alignment system 100
The ultimate range that can be positioned is l*cos (β -90 °).
It is thus possible to the distance of the distance display device 150 of first laser receiver 121 is got, by every path institute
Straight line it is parallel with the place plane of display device 150, therefore the distance of the distance display device 150 of interactive device 130 is,

The drive module of receiver 121, the drive module of generating laser 111 are connected with generating laser 111, and laser pickoff 121 drives
Module is connected with laser pickoff 121, and multiple drive modules of generating laser 111 are used to swash by the driving of the first predeterminated frequency is multiple
Optical transmitting set 111 works, and multiple drive modules of laser pickoff 121 are used to drive multiple laser pickoffs by the first predeterminated frequency
121 work.
Further, control device 140 can be with generating laser 111 corresponding to the row generating laser 111 of a secondary control one
Drive module works, to drive a row generating laser 111 transmitting laser；Control device 140 is driven by laser pickoff 121
Module controls a row laser pickoff 121 corresponding to the row generating laser 111 to be completed in certain clock frequency, keeps swashing
The synchronism that light is launched and received.
In addition, the generating laser 111 and laser of the first row of Laser emission array 110 and laser pick-off array 120
Receiver 121 can be that Laser emission and laser pick-off are completed in a clock cycle, then the generating laser 111 of next column
Worked again with laser pickoff 121, by that analogy, control last of Laser emission array 110 and laser pick-off array 120
Row generating laser 111 and laser pickoff 121 complete work, process of the whole process as single pass.Also, once sweep
And then scanned next time after retouching end, repeatedly, the frequency of scanning can be 0~60Hz for circulation.Certainly, the frequency of scanning can be with
Set according to the actual requirements, concrete numerical value is not intended as limiting in embodiments of the present invention.Scan frequency is higher, the precision of positioning
It is then better with flatness.
In embodiments of the present invention, the length of Laser emission array 110 and laser pick-off array 120 can be l, laser
The line-spacing of emission array 110 and laser pick-off array 120 can be default line-spacing x, and the length of display device 150 can be
Preset length w, the cross section of interactive device is highly u, then x scope is tg (1 °) * (w+2*l*sin (β -90 °))<x<u.
It is understood that if default line-spacing is too big, interactive device 130 is likely to occur just in two adjacent light
Between learning path, prevent interactive device 130 from obstructing the light.If default line-spacing is too small, the correspondence of adjacent light path can be made
Laser pickoff 121 disturb.
