Specific implementation mode
Below according to 2~Fig. 3 of attached drawing, the preferred embodiment of the utility model is provided, and is described in detail, is enabled more preferable
Ground understands the function of the utility model, feature.
Referring to Fig. 2, a kind of adjustable Laser Triangulation Measurement System Based of range of the utility model embodiment, including a laser
Emitter 1, a diaphragm 2, a lens 3 and a reception device 4, diaphragm 2 are set between laser beam emitting device 1 and a determinand
One first light path on；Lens 3 are set in one second light path between reception device 4 and determinand；Diaphragm 2 forms multiple
The width of lyriform pore 21, each mesopore 21 is different.
In the present embodiment, each mesopore 21 corresponds to a measuring range, the width of measuring range more big corresponding mesopore 21
Bigger, measuring range is the distance between lens 3 and determinand.
Each mesopore 21 opens up and in the horizontal direction along the spaced laying of 2 vertical direction of diaphragm.Mesopore 21 is according to institute
The size of corresponding measuring range is arranged in order, and the spacing between adjacent two mesopore 21 with the increase of corresponding measuring range and
Reduce.
Fig. 2 and Fig. 3 are please referred to, a kind of range based on the adjustable Laser Triangulation Measurement System Based of the present embodiment range is adjustable
Laser triangulation method, including step：
S1：Establish the adjustable Laser Triangulation Measurement System Based of range in the present embodiment；
S2：Select the mesopore 21 corresponding to current desired measuring range；
S3：Adjust the position of laser beam emitting device 1 and mesopore 21 so that laser beam emitting device 1 and mesopore 21 are located at
In first light path；
S4：Complete the measurement that current measure journey corresponds to determinand；The intensity for the laser that laser beam emitting device 1 emits and survey
Measure range inversely, the optical axis of laser is corresponding with the center of mesopore 21；
S5：Judge whether the measuring range not detected also；If any return to step S2；Such as without end step.
Such as it is needed to the first measuring range after the adjustable Laser Triangulation Measurement System Based of range in establishing the present embodiment
When one first determinand M and one second determinand M ' of the second measuring range are measured, selection and the first measuring range first
Corresponding 1 first mesopore 21 adjusts the position of laser beam emitting device 1 and the first mesopore 21 so that laser beam emitting device 1
It is located in the first light path with the first mesopore 21；Start laser beam emitting device 1 and emits laser to the first determinand M along the first light path
And one first hot spot is formed on the first determinand M, reception device 4 obtains the light of the first hot spot by lens 3 along the second light path
Signal；According to the center of the first angle a and laser beam emitting device 1 of the first light path at this time and the second light path and 3 center of lens
The first distance d calculate the first determinand M between lens 3 at a distance from, complete to close laser beam emitting device 1 after measuring.Then it needs
When being measured to one second determinand M ' of the second measuring range, corresponding with the second measuring range one second is selected first
Mesopore 21 adjusts the position of laser beam emitting device 1 and the second mesopore 21 so that laser beam emitting device 1 and the second mesopore
21 are located in the second light path；Laser beam emitting device 1 is opened so that laser after the second mesopore 21 by exposing to the second determinand
One second hot spot is formed on M ', reception device 4 obtains the optical signal of the second hot spot by lens 3 along the second light path；According at this time
The second distance d ' at the center and 3 center of lens of the second angle a ' and laser beam emitting device 1 of the first light path and the second light path
Calculate the second determinand M ' between lens 3 at a distance from, complete measure after close laser beam emitting device 1.
In the present embodiment, by the mesopore 21 to designing multiple and different width and spacing on diaphragm 2, laser is allowed to pass through light
Late 2 different mesopores 21 achieve the purpose that realize multiple measuring range section switchings.
The width of mesopore 21 needs the basic demand for meeting laser triangulation, and laser can be allowed to pass through without generating laser
Diffraction, while meeting the requirement of corresponding measuring range section luminous intensity；The pitch requirements of mesopore 21 meet laser beam emitting device 1
Single laser beam meets the measuring range requirement of theoretical calculation by without generating adjacent interference；The height of 2 substrate of diaphragm
Size and the quantity of mesopore 21 are set according to the actual size of laser triangulation module, on theoretical upper substrate between how many
Lyriform pore 21, you can realize the measurement of how many range sections.
Because laser be directional light, theoretically 21 width of mesopore be equal to determinand on hot spot size, and with determinand away from
It is uncorrelated from being worth；For laser intensity with apart from inversely proportional relationship, the value of 21 width of mesopore is directly proportional to laser intensity, obtains
Conclusion, 21 width of mesopore of design and testing distance direct proportionality, that is, when testing distance is remote, 21 width of mesopore
Design size becomes larger.
The corresponding mesopore 21 not existed together, it is desirable that the optical axis for emitting laser is overlapped with the center of mesopore 21,
To obtain more uniform hot spot, ensure the measurement accuracy of system.
