Abstract
The utility model discloses a kind of New Image spirit-leveling instrument, be provided with housing (1), level (11) and alignment clamp (13), object lens (2), focusing lens (3), focusing screw (4), automatic horizontal sight line compensator (5) and crosshair graticule (6) is provided with in the horizontal direction from outside to inside successively in housing (1), crosshair graticule (6) afterwards correspondence be provided with electro-optical imaging sensors (7), electro-optical imaging sensors (7) be arranged on housing (1) aobvious control terminal (8) outward and connect.Directly electronic surveying can be carried out to common levelling staff, achieve the effective integration of artificial reading and electronical reading, taken into account the advantage of the two, both there is intuitive and the reliability of artificial observation, there is again efficient, the high precision rate of electronical reading, reduce cost simultaneously.
Description
Technical field
The utility model relates to a kind of leveling device, especially provides the New Image spirit-leveling instrument that a kind of cost is low, can carry out electronical reading to common levelling staff.
Background technology
Known leveling device is made up of a spirit-leveling instrument and two levelling staffs.The primary structure of spirit-leveling instrument is provided with housing, is provided with object lens, focusing lens, focusing screw, eyepiece, eyepiece focusing spiral, crosshair graticule, spectroscope and figure reading electronic device (one dimension CCD) composition in housing.Levelling staff is divided into common levelling staff and coding levelling staff, and common levelling staff is used for surveyor and uses the eyepiece of spirit-leveling instrument to carry out the artificial reading of optics, and the figure reading electronic device (one dimension CCD) that coding levelling staff is used for spirit-leveling instrument carries out electronics automatic reading.Level, alignment clamp and pedestal etc. are also had in spirit-leveling instrument housing outer end.First two levelling staffs are placed in respectively ground A, B 2 point during measurement, again spirit-leveling instrument is arranged on the centre position of A, B 2, after utilizing leveling, the horizontal line of sight of spirit-leveling instrument sights the absolute altitude numerical value (the middle silk of crosshair intercepts the reading on levelling pole) of reading two levelling staffs respectively with object lens, the difference of institute's mark height numerical value is the height differences by leveling of ground A, B 2, if known elevation wherein, the elevation of another point can be extrapolated by the discrepancy in elevation.Exist following not enough: (1) uses eyepiece to carry out the artificial reading of optics according to common levelling staff, then precision is low, efficiency is low; (2) utilize the electronic CCD reader of spirit-leveling instrument to carry out automatic reading according to coding levelling staff, though the precision of improve and efficiency, there is the problem being manually beyond recognition coding levelling staff; (3) if arrange common levelling staff and coding levelling staff simultaneously, then measurement cost is added.
Summary of the invention
The utility model is the problems referred to above in order to solve existing for prior art, provides the New Image spirit-leveling instrument that a kind of cost is low, can carry out electronical reading to common levelling staff.
Technical solution of the present utility model is: a kind of New Image spirit-leveling instrument, be provided with housing, level and alignment clamp, object lens, focusing lens, focusing screw, automatic horizontal sight line compensator and crosshair graticule is provided with from outside to inside successively in the horizontal direction in housing, after crosshair graticule, correspondence is provided with electro-optical imaging sensors, and electro-optical imaging sensors connects with the aobvious control terminal be arranged on outside housing.
The utility model adopts two dimensional image recognition technology directly to carry out electronic surveying to common levelling staff, achieve the effective integration of artificial reading and electronical reading, take into account the advantage of the two, both there is intuitive and the reliability of artificial observation, there is again efficient, the high precision rate of electronical reading, reduce cost simultaneously.
Accompanying drawing explanation
Fig. 1,2 is structures of the utility model embodiment 1 and uses schematic diagram.
Fig. 3 is the structural representation of the utility model embodiment 2.
Embodiment
Embodiment 1:
As shown in Figure 1, 2: be provided with the housing 1 that the material such as metal, fiberglass is made, object lens 2, focusing lens 3, focusing screw 4, automatic horizontal sight line compensator 5 and crosshair graticule 6 is provided with in the horizontal direction from outside to inside successively in housing 1, after crosshair graticule 6, correspondence is provided with electro-optical imaging sensors 7, electro-optical imaging sensors 7 connects with the aobvious control terminal 8 be arranged on outside housing 1, be provided with level 9 in the exterior lateral sides of housing 1, be provided with alignment clamp 10 in the outer tip end of housing 1.Electro-optical imaging sensors 7 adopts cmos image sensor, aobvious control terminal 8 is made up of single-chip microcomputer, display module, control module and communication module, single-chip microcomputer adopts based on the special software of OPENCV platform development or other image recognition processing software, carries out identifying processing to the picture signal that electro-optical imaging sensors 7 exports.
The use course of work of embodiment 1 is as follows:
(1) like the prior art, spirit-leveling instrument 1 and scale 20 is settled;
(2) slightly flatten: using level 9 by regulating relevant spiral, making bubble placed in the middle;
(3) focusing is sighted: using alignment clamp 10 to make spirit-leveling instrument 1 sight scale 20, and use imageing sensor 7 and aobvious control terminal 8, by regulating focusing screw 4, making the delineation 21 of levelling staff 20 reach clear state.
(4) observed reading: use scale 20 image of aobvious control terminal 8 pairs of imageing sensors 7 to process, obtain the altitude information of delineation 21 corresponding to levelling staff 20 image.
Embodiment 2:
As shown in Figure 3: substantially identical with embodiment 1 structure, difference is as follows: electro-optical imaging sensors 8 adopts CCD or LCOS or DLP imageing sensor, and aobvious control terminal 8 is by based on mobile phone or panel computer or notebook computer.
Use the course of work with embodiment 1.
