Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
As shown in Figure 1, a kind of laser width finding centering device, the present apparatus can realize that the wide function of survey may further be realized in fixed
Function surveys wide function in one embodiment in order to realize, the present apparatus includes combination laser device Q1, combination laser device Q2, line
Property CCD, fixed plate, signal processor, combination laser device Q1 rotatably fixes device by first and connect with fixed plate, by the
One rotatably fixes device, and combination laser device Q2 rotatably fixes device by second and connect with fixed plate, combination laser device Q1
It issues the vertical laser vertical directive determinand surface towards determinand and the rotation for rotatably fixing device by first drives
The laser of combination laser device Q1 towards determinand angle, combination laser device Q2 issue towards determinand vertical laser and pass through
Second rotation for rotatably fixing device drives angle of the laser of combination laser device Q2 towards determinand, and linear CCD array is set
It sets in the top of combination laser device Q1, Q2, the laser point formed on the test object for acquiring laser, signal processor difference
Connect linear CCD, angular transducer, angular transducer can be used two, angular transducer detect respectively combination laser device Q1,
The angle that the laser point of combination laser device Q2 on the test object is rotated by initial position to determinand edge, signal processor are used
In calculating determinand width according to the data of linear CCD, angular transducer.
Combination laser device Q1, Q2 are used to issue cross one another two laser respectively and form laser point in crosspoint,
The laser point of intersection is bright most strong in determinand pediment.Linear CCD camera acquires the laser point shot on determinand after passing through lens.
First, which rotatably fixes device, second, rotatably fixes device using identical structure, and size is consistent,
The position of combination laser device setting is also identical, and the laser point of the laser of sending is on the horizontal plane of sustained height.As shown in Fig. 2,
For the setting schematic diagram of laser Q1, first rotatably to fix device include support rod 3, and 3 one end of support rod passes through bearing setting
Can horizontally rotate in fixed plate, combination laser device Q1 or Q2 is fixedly installed for the other end so that combination laser device Q1 or Q2 are sent out
Laser out is perpendicular to determinand.Support rod 3 is vertically arranged in fixed plate 1, and mounting groove is provided in fixed plate and is being pacified
Bearning mechanism, the bottom end connection of Bearning mechanism and support rod are provided in tankage, laser is fixedly installed in the other end of support rod
Q1, such support rod by way of bearing with fixed plate due to being connect, so that it may be rotated by way of bearing, to drive
The rotation of laser, in initial position, the laser that laser issues is vertical-horizontal transmitting, and is vertically fallen on the test object,
The upper end of laser Q1 is provided with CCD camera, the image that CCD camera acquires the laser point on determinand by optical element is believed
Number, filter is set in front of the collection terminal of CCD camera picture signal, CCD camera is attached in fixed plate by fixed mechanism,
It plays a supporting role, it is of course possible to realize that the support for CCD camera is fixed using a variety of different set-up modes.It is fixed
Position mainly can satisfy clearly acquisition laser point image.
In order to realize rotation, it is equipped with knob 6 in the end of the setting combination laser device of support rod, is rotated and is adjusted by knob
Combination laser device is that axis is rotated along support rod.Knob is set at the top of support rod, support rod is driven by knob
And corresponding laser Q1 is rotated under the action of bearing, thus the laser point of mobile laser on the test object.Knob X1, X3
Respectively drive the knob of Q1, Q3 rotation, it is ensured that Q1 can only be rotated and can only be rotated in the horizontal direction by X1.Ensure that Q3 can only be by
X3 is rotated and can only be rotated in the horizontal direction.
As shown in figure 3, being top view, it is phase that the application first, which rotatably fixes device, second and rotatably fixes device,
Same structure, and the position for the laser being arranged thereon, height etc. are all the same, swash to guarantee that two laser points are corresponding
It is in same level between the line of light device.
Signal processor is connect with display panel, for shown by display panel measure determinand width information and
Or rotation angle information.Signal processor calculates corresponding width data according to the preset formula for calculating data, then leads to
It crosses display panel and carries out display to achieve the purpose that calculate width.
In measurement, initial position, laser are perpendicular to determinand first, then will fall in such a way that knob rotates
Laser point on the test object is moved to the edge of determinand, laser point on such determinand and between the launch point of laser
Line corresponding can find determinand edge, the take pictures image of acquisition of CCD is shown by display interface and facilitates confirmation laser
Whether point reaches edge.In moving process, due to the angle-data for acquiring the rotation that can be arrived in real time of angle, when turning to
When edge, line can be as at triangle between laser emission point, laser drop point on the test object and CCD imaging point three
Shape, due to CCD up to the top in laser and position is fixed, then laser point to CCD positional distance belongs to constant and (also first surveys
Amount), angle also belongs to constant, it is illustrated in figure 6 illustraton of model,
B2 is Q1 laser emission point, and B is that laser drop point, B1 are the imaging point on CCD on the test object.B2 point is fixed, B1
Point is fixed, and filter position fixes, thus angle a2 it is known that B2B1 length c1 it is known that laser is only rotated in horizontal position, angle [alpha] 1
It is known that known two interior angles, then in △ ABC, angle a3 is it is known that calculate the length of c by the cosine law.
The cosine law: c=c2*cos (a3)+c1*cos (a1)
C2=c1*cos (a2)+c*cos (a3)
It is derived from: c=[c1*cos (a2) * cos (a3)+c1*cos (a1)]/[1-cos (a3) * cos (a3)]
To show that the length of a laser rays measures out the laser of corresponding Q1 when being moved to the edge of determinand
The laser length of length and Q2.
When laser point edge in determinand respectively, schematic diagram is as shown in fig. 7, in a horizontal plane, as long as calculating
The distance of two laser drop points can indicate the width of determinand.
In Fig. 7, A is Q1 laser emission point, and D is laser drop point, and B is Q3 laser emission point, and C is laser drop point.AB point
Distance d is fixed, and Q1 rotational angle β passes through angular transducer it is known that Q2 rotational angle γ passes through angular transducer it is known that by Fig. 7
Model it is found that AD length a (laser length) it is known that BC length b (laser length) it is known that seeking the length of c.
In △ AOB, ∠ OAB=90- β；∠ ABO=90- γ；α=β+γ.
Using the cosine law: e=d*cos (∠ OAB)+f*cos (α)
F=e*cos (α)+d*cos (∠ ABO)
It is derived from:
E=[d*cos (∠ ABO) * cos (α)+d*cos (∠ OAB)]/[1-cos (α) * cos (α)]
=[d*cos (90- γ) * cos (β+γ)+d*cos (90- β)]/[1-cos (β+γ) * cos (β+γ)]
F=[d*cos (∠ OAB) * cos (α)+d*cos (∠ ABO)]/[1-cos (α) * cos (α)]
=[d*cos (90- β) * cos (β+γ)+d*cos (90- γ)]/[1-cos (β+γ) * cos (β+γ)]
Then in △ DOC, it is known that OD length is a+e, and OC length is b+f, and α=β+γ seeks c.
Using the cosine law:
c2=(a+e)2+(b+f)2-2(a+e)(b+f)cos(β+γ)
It then obtains: c=[(a+e)2+(b+f)2-2(a+e)(b+f)cos(β+γ)]1/2Formula (1)
To which the distance between two laser points be calculated.Signal processor according to the angle information of rotation, and
Then operation above-mentioned formula can both calculate width automatically for the angle and length on basis etc., then on a display screen into
Row display surveys wide effect to realize.
