Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Shown in Fig. 4, visualization laser receiver of the present invention comprises: photosensitive array 1, controller, the visualization interface 2 of more than one group.Controller drives photosensitive array 1 and receives its feedback signal, and visualization interface 2 is under control of the controller with visual pattern simulation measured laser; Controller forms with visualization interface 2, photosensitive array 1 and is electrically connected.
Wherein photosensitive array 1 comprises multiple photosensitive unit, and these photosensitive units can be the photovalves such as CCD chip, CMOS chip or PSD chip (Position Sensitive Detector, position sensitive detector).Visualization interface 2 refers to the human-computer interaction interface that can be supplied to user's visual image, and as preferably, visualization interface 2 comprises: for the display screen 201, the control panel 202 for controlling and inputting that show.
Photosensitive array 1 is made up of with the array of certain forms photosensitive unit, and in order to utilize minimum photosensitive unit to realize detection, as a kind of preferred version, photosensitive array 1 is made up of a row photosensitive unit of line spread.The reason of such setting is, design concept of the present invention is, lasing area A can be shown in a linear fashion on visualization interface 2, under normal conditions, lasing area A for measuring is level or vertical, first the object that we will realize is, can catch or receive this lasing area A, and next is to demonstrate this lasing area A with the form of straight line (being line segment on limited visualization interface 2) on visualization interface 2 intuitively.We know and determine straight line (because lasing area A comes to be straight line section along projecting direction projection), and the photosensitive array 1 that a row photosensitive unit of line spread is formed namely can one of them point of positioning linear, as long as this straight line is not parallel with it.So this preferred version is the most effectively and is also most cost-saving, certainly, other forms of such as rectangle, circle and annular photosensitive array 1 also can implement the present invention, fall into protection scope of the present invention.
As a kind of preferred version, the number of the photosensitive array 1 become by photosensitive unit line spread is 2, be separately positioned on the both sides of visualization interface 2, so, when lasing area A can project on such two photosensitive arrays 1, what the corresponding photosensitive unit of photosensitive array 1 detected arrives laser beam, the line Segment simulated laser face A that the position of the result that controller detects according to photosensitive array 1 and concrete photosensitive unit shows with display screen 201 on visualization interface 2 is normally incident upon the line segment on visualization interface 2, concrete way is, first controller determines that both sides photosensitive array 1 detects the specific position of lasing area A, then controller controls display and demonstrates a line segment pattern (because restriction of display screen 201 screen size), namely this line segment pattern is the visualization pattern that lasing area A is incident upon on display screen 201.
It should be noted that, the left and right sides of visualization interface 2 mentioned here, refer to the both sides that visualization interface 2 interface zone is relative, when measuring the lasing area A of level, we wish or we make photosensitive array 1 be positioned at the both sides of the level of visualization interface 2 by arranging, namely left, right both sides, the straight-line segment that now photosensitive unit arrangement is formed is parallel to vertical direction, lay respectively at the left and right sides of visualization interface 2, as long as now the lasing area A of level is in the scope of photosensitive array 1, inherently be displayed on visualization interface 2, certainly we can by adjusting the whole height position of visualization interface 2 and photosensitive array 1 formation, aim at lasing area A, even if when the straight-line segment certainly formed in photosensitive unit arrangement departs from vertical direction slightly, as long as lasing area A can be radiated on photosensitive array 1 simultaneously, visualization interface 2 still imaging can show the line segment representing lasing area A, just now visualization interface 2 has also deflected, us may be made cannot to complete the work of correction, so we still wish at the lasing area A(of reception level or want to realize level and the lasing area A that needs receiver to correct according to measuring object) time, we need the entirety ajusting visualization interface 2 and photosensitive array 1 formation, make photosensitive unit arrange the straight-line segment formed and be parallel to vertical direction.
Want to realize level and the lasing area A that needs receiver to correct to vertical lasing area A(or according to measuring object), we still adopt relative both sides to arrange linear pattern photosensitive array 1(namely to form photosensitive array 1 by a row photosensitive unit of line spread in fact, scheme down together), only in order to vertical lasing area A can be detected, our desirably vertical both sides, these both sides, this also can make for realization by aforementioned schemes is rotated 90 degree by photosensitive array 1 is arranged on vertical both sides to realize.
In order to in reality, not only there is the lasing area A of level but also there is vertical laser when all needing to receive simultaneously, as a kind of preferred version, the number of photosensitive array 1 is 4, is separately positioned on the four direction of visualization interface 2; Namely be equipped with photosensitive array 1 at two couple of visualization interface 2 four direction facing each other.
As further preferred, visualization interface 2 has the profile of rectangle, is all parallel to the outline line of visualization interface 2 tool of its side, place at the linear pattern photosensitive array 1 of its surrounding.
In order to after visualization interface 2 shows lasing area A position, calibration operation can be realized, as a kind of preferred version, also comprise in laser pickoff of the present invention: calibrating installation 3.Specifically, calibrating installation 3 can be mechanical bubble also can be Electronic bubble, if Electronic bubble, then itself and controller realize being electrically connected.
When specifically carrying out work, first the position of visualization interface 2 is calibrated by calibrating installation 3, make it as the object of reference of reference standard, such as scale line (can be scale in kind form also can be display screen 201 show virtual line segment) etc. carry out level or vertical location, then gone to the position of calibration of laser face A further by them.
As a kind of preferred version, the display screen 201 of visualization interface 2 is dot matrix display screen, when there is calibrating installation 3 and determine that received lasing area A is the surface level or vertical plane determined, a photosensitive array 1 can be only set, because now known laser face A level or vertical time, only need a point can determine representing its virtual line segment, what the lasing area A for level adopted is vertical linear pattern photosensitive array 1, for the vertical linear pattern photosensitive array 1 then adopting level, in addition, display screen 201 can adopt segment encode display screen, during reception, make the segment encode of segment encode display screen horizontal or vertical by putting.
It should be noted that, having multiple level while during the A of Emission Lasers face, controller can judge whether belonged to same lasing area A by multiple laser rays that photosensitive unit detects, the point position belonging to same lasing area A only can be demonstrated line segment by it on screen, different line segment can go to distinguish display by the gray scale of screen, color, thickness etc., when running into None-identified and estimate of situation, can adopt in screen edge corresponding position flicker, judge voluntarily to point out user or adjust the laser surveying instruments such as level.
Its middle controller can carry out judging whether the multiple laser rays by photosensitive unit detects belong to same lasing area according to difference such as the wavelength of laser, signal amplitude, pulsed frequencies.Such as, utilize the difference of signal amplitude, when there being multi-stripe laser line to get on photosensitive array, because distance is the factor of laser power, cause different laser rays to have difference at signal amplitude, and the relative magnitude of same laser line on different photosensitive array is constant, therefore, by the judgement of relative signal amplitude, just the signal on different photosensitive array can be matched, thus many lines can be drawn.Again by the power of amplitude, the thickness and the shade that change lines show on display screen 201.Wherein under single color display screen, different lines can be distinguished by the thickness of lines, with under the single color display screen of gray scale, different lines can be distinguished by grayscale table.
Can certainly be identified by the mistiming of laser rays, the mistiming refers to that pulse generating time is inconsistent, can judge the priority of light, thus distinguishes multiple laser rays and whether belong to same lasing area A.Under pulse laser condition, display screen 201 also linearly can show different lasing area by different respectively, namely can be distinguished by the line of flicker or the line continuing display.In sum, visualization laser receiver of the present invention intuitively, in real time can manifest laser position, the restriction in non-angular and place during use, arbitrarily angledly all can use, and positioning time is short, and within usual 1s, precision is high, within usual 1mm.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
