Point precision.Detect laser level performance and precision, by industrial camera complete to horizontal line, vertical line, cross hairs identification, with
Reach the detection of the parameter in summarizing laser level demand.
1st, horizontal accuracy
Horizontal accuracy includes two aspects, and one is horizontal i angles, and two be horizontal linear degree, describes scanner with absolute
Horizontal datum upper and lower translation is qualified in accuracy rating.
1) i angles detection method
The different target of two distances is set up in front of instrument stand, two targets of demarcation are equal apart from ground level, No. 1
Target 10 and No. 2 longitudinal separations of target 20 are 1 meter (two root posts are apart from L=1 meter), and making its left and right placement, (front target does not block rear target light
Line).The Y-axis for demarcating two targets is parallel, and X-axis is parallel.The adjustment lifting platform light that scans out instrument was tried one's best Y in No. 2 targets 20
The ray position received in 0 point of axle, No. 1 target 10 of observation.If the light that two targets are received and two target Y-axis intersection point phases
Together, then illustrate that i angles are not present in instrument, it is on the contrary then there is i angles.As shown in Fig. 2 the coordinate shown according to display is read accordingly
Numerical value, calculates i angles.
Calculation formula：I angles=arctan (y2-y1)/L；
y1：Measure the intersection point of the y-axis of straight line and No. 1 target 10；
y2：Measure the intersection point of the y-axis of straight line and No. 2 targets 20.
2) horizontal linear degree
First by turntable angle system zero during testing level linearity, after Y-axis on observation light after instrument stabilizer and No. 2 targets 20
Intersection point, record the value for y1,45 degree of turntable of rotation or some angle, after reading now light and No. 2 after instrument stabilizer
The intersection point of Y-axis is recorded as y2 on target 20, and the step is repeated again and takes y3, and comparing a, b, c tri- according to equation below is worth variable quantity,
Horizontal linear degree precision is the maximum in abc.If three values are identical, it is a horizontal line to illustrate this straight line, is not deposited
Changing up and down, it is on the contrary then calculate its deviation.
Calculation formula：A=| y1-y2 |；
B=| y1-y3 |；
C=| y2-y3 |.
2nd, vertical precision
As shown in figure 1, No. 2 targets 20 and No. 3 targets 30 are set up, make the Y-axis of two target heads parallel, after after instrument stabilizer points
The ray position that Guan Cha do not receive in two targets.If the light that two targets are received is identical with two target X-axis intersection points,
It is a horizontal vertical line to illustrate this straight line, on the contrary then calculate its deviation.
Calculation formula：A=| x2-x3 |；
x2：Measure the intersection point of the X-axis of straight line and No. 2 targets 20；
x3：Measure the intersection point of the X-axis of straight line and No. 3 targets 30.
3rd, orthogonal precision
As shown in figure 1, far and near place of No. 3 targets 30 and No. 4 targets 40 can measure angle of the light in X-direction, instrument is swept
Go out vertical plane that vertical plane demarcated centered on instrument with No. 3 targets 30 and No. 4 targets 40 in horizontal offset, calculate and be recorded as
q.90 degree of next vertical planes of relief of rotary apparatus enter No. 3 targets 30 and No. 4 targets 40, similarly calculate and are recorded as w angles and (calculate angle
Have positive and negative).The actual angle c angles calculated with two angles of q, w and accurately rotate 90 degree between two vertical planes.
Calculation formula：Q=arctan ((x31-x41)/l)；
W=arctan ((x32-x42)/l)；
Orthogonal precision=the 90+q+w of c=；
x31：Straight line and the intersection point of x-axis are measured on No. 3 targets；
x41：Straight line and the intersection point of x-axis are measured on No. 4 targets；
x32：It is rotated by 90 ° on rear No. 3 targets and measures straight line and the intersection point of x-axis；
x42：It is rotated by 90 ° on rear No. 4 targets and measures straight line and the intersection point of x-axis；
l：The distance between No. 3 targets and No. 4 targets.
4th, to a precision on
As shown in figure 1, on No. 5 targets 50 are direct plungeed into a cross light.Instrument is set up and finished, instrument stabilizer postscript is treated
Record the coordinate of cross searching in No. 5 targets 50, rotary apparatus 180 degree, after recording the data after instrument stabilizer again；Rotary apparatus 45
Record data is spent, again rotary apparatus 180 degree record data；Repeat the step several times after comparing calculation recorded to point value
Deviation, judge upper whether qualified to point.
Calculation formula：The half of record data coordinate distance when di=any twos are mutually 180 degree angle；
Maximum of which di values are on to a precision.
5th, it is lower to a precision
As shown in figure 1, lower put into No. 1 target 10 (or No. 2 targets to dot laser point using the speculum for being calibrated instrument bottom
20).Instrument is set up and finished, after the coordinate that cross searching in target is recorded after instrument stabilizer, rotary apparatus 180 degree treats instrument
The data are recorded again after stable；45 degree of record datas of rotary apparatus, again rotary apparatus 180 degree record data；Repeat the step
Whether the deviation to point value that rear comparing calculation is recorded several times suddenly is qualified to putting under judgement.
Calculation formula：The half of record data coordinate distance when di=any twos are mutually 180 degree angle；
Maximum of which di values are lower to a precision.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
