Heart point, considerably increases the applicability of the device.
Description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is a kind of projection status diagram of calibration slewed laser beam grenade instrumentation of the utility model embodiment；
Fig. 2 is the central point of diagonal spot each other in four spots in the first image plane and in the second image plane in Fig. 1
Line schematic diagram.
Specific implementation mode
Referring to figs. 1 to Fig. 2, the utility model embodiment a kind of calibration slewed laser beam grenade instrumentation, including fixed seat 2
And be rotatably connected on the laser beam projects device 1 in fixed seat 2, along the projecting direction of laser beam projects device 1 set there are one or
Multiple image planes, laser beam projects device 1 are connected with driving mechanism, laser beam projects device 1 after 0 ° of initial position projects, according to
The position of secondary rotation to 90 °, 180 ° and 270 ° completes to project, including laser beam projects device 1 four different positions in image plane
Set the spot 5 projected successively.
It is calibrated using the present apparatus, laser beam spots precision calibration link can be removed from, saved the time, operation letter
Just.Laser beam projects device 1 completes projection directly in 0 °, 90 °, 180 ° and 270 ° four symmetric positions, is formed in image plane
The consistent spot 5 of four corresponding profiles finds the central point of spot 5 by handling the profile of spot 5, then by four spots 5
In connect into line between the central point of diagonal spot 5 each other, finally determine that the intersection point of two lines is the central point in image plane,
Line centered on line between each image plane central point, the center line are Calibration Base Line.Meanwhile school is carried out using the device
Standard, whether the profile for being not limited to spot 5 is regular, need to only find the central point of four 5 constituted spot set of spot, greatly
The applicability of the device is increased greatly.
Specifically, fixed seat 2 includes holder 21 and shaft 22, and holder 21 is placed on ground or workbench, makes
Height and the horizontal height to be calibrated for obtaining laser beam projects device 1 are almost the same, and shaft 22 is horizontal to be set to 21 top of holder
And be rotatablely connected with it, in the present embodiment, the rotation connection with holder 21 is realized at the both ends of shaft 22 by rolling bearing.Swash
1 fixed and arranged of light-beam projecting device follows shaft 22 to rotate together in the end of shaft 22.Simultaneously in laser beam projects device
1 projecting direction is equipped with the first image plane 3 and the second image plane 4.
Preferably, the central point of the laser 11 of laser beam projects device 1 is located at the gyration central axis 221 of shaft 22
On.Although carry out horizontal alignment using the device, the calibration that horizontal accuracy is carried out to laser beam projects device 1 is not needed to,
But when arranging laser beam projects device 1, still ensure the central point of the laser 11 of laser beam projects device 1 as far as possible
It in the gyration central axis 221 of shaft 22, avoids the spacing in image plane between spot 5 excessive, and then increases to measure and miss
Difference.
Preferably, between the slewing area of laser beam projects device 1 is 0 ° to 270 °.Laser beam projects device 1 is driving
Motivation structure is rotated by, and due to being connected with power cord and control line on laser 11, limits laser beam projects device 1
Slewing area be 0 ° to 270 ° so that power cord and control line are unlikely to wind rotary shaft.
A kind of calibration method of calibration slewed laser beam grenade instrumentation, includes the following steps：
A, 1 level of laser beam projects device is put, and in location arrangements image plane to be calibrated；
B, start laser beam projects device 1, and first time projection is carried out in 0 ° of initial position；
C, drive laser beam grenade instrumentation 1 rotates, and is sequentially completed projection 90 °, 180 ° and 270 ° of position respectively；
D, the spot 5 for handling corresponding four positions in image plane, finds the center of four consistent spots of profile 5 respectively
Point；
E, the line between the central point of diagonal spot 5 each other is drawn in four spots 5, determines that the intersection point of two lines is
Central point in image plane, the line between each image plane central point are calibration center line.
It is projected since laser beam projects device 1 is limited to 0 °, 90 °, 180 ° and 270 ° four symmetrical launching position point,
And the consistent spot 5 of four profiles is formed in image plane, even if laser beam projects device 1 is not exclusively located at horizontality
The central point in image plane can be determined by the central point of four spots 5, the company between central point in multiple image planes
Line is determined as Calibration Base Line.Calibration Base Line can quickly be obtained using this method, it is efficient.Also, even if the profile of spot 5 is not advised
Then, it is applied equally to this method.Because the four launching position points selected in this method are symmetrical, the profile of spot 5 can
Think arbitrary shape, does not interfere the determination of the central point in image plane.
The embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
State embodiment, the technical field those of ordinary skill within the scope of knowledge, this practicality can also not departed from
Various changes can be made under the premise of novel objective.
