Background technology
Industrial photogrammetry is a kind of important method implementing commercial measurement, camera is utilized to take photograph to measured target, by image procossing and Photogrammetric Processing, to obtain geometric configuration and the motion state of target, can be used for solving measurement problem relevant to the shape of target, size and motion state etc. in industrial part design, manufacture, installation, setting-out, detection, quality control and dynamic monitoring.According to the difference of metering system, industrial photogrammetry can be divided into the off line measurement pattern adopting one camera and the on-line measurement pattern adopting polyphaser.The former mainly measures static object, adopts separate unit digital camera to take measured object in two or more position and then image is imported computing machine and can process; The latter mainly measures dynamic object, adopts multiple stage digital camera to take measured object simultaneously, and is processed in real time to computing machine by image transmitting by connecting line.
Digital photogrammetry is the digital picture of more than 2 width by obtaining same object in different positions and direction, obtains the accurate three-dimensional coordinate of tested point after the process such as machine image characteristics extraction as calculated, orientation, coupling and relevant mathematical computations.
In above-mentioned digital photogrammetry process, the surface of a lot of testee there will be the hidden places such as depression, as the precision measure of work pieces process.The hidden place of these recessed position is because can not use digital camera directly to take well, also the three-dimensional coordinate information of these hidden places cannot just be collected, and exactly the three-dimensional coordinate of these hidden places is exactly judgment basis important in checking Workpiece Machining Accuracy process, thus cannot obtains hidden place three-dimensional coordinate information and be restricted with regard to the range of application that directly results in digital photogrammetry.For increasing the measurement of hidden place, just become by the subsidiary hidden place of outside workpiece the important way addressed this problem.
For the measurement of hidden place, the measurement light pen produced from the Mai Zhuonuo measuring system company limited of company (Metronor AS) of the absorbed digital photogrammetry of Norway solves this technological difficulties, this measures light pen is CLP5500, this light pen is installed infrarede emitting diode (LED) mark that 5 relative coordinates are known, by obtaining the image of light emitting diode on light wall during measurement, the relation that can try to achieve light pen place coordinate system fast and take the photograph between station coordinates system, thus the coordinate recording unknown point (light pen gauge head institute contact point).This measurement light pen adopts carbon fibre material manufacture to form, need by inside install minicell be LED power realize Active Imaging auxiliary camera shooting, not only there is the problems such as complex structure, processing inconvenience, fragile, the maintenance difficult of LED, also directly results in cost and the after-sales service somewhat expensive of this measurement light pen, order a lot of consumer group in the industry hang back, and cannot reach the effect promoting digital photogrammetry application.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the utility model is just to provide a kind of measuring pen for industrial photogrammetry system, effectively can solve existing measuring pen complex structure, difficulty of processing is large, LED is fragile, maintenance difficult, cost be high, the problem of maintenance cost costliness.
The technical scheme that the utility model solves is, comprise panel and pole, the central vertical of panel is equipped with pole downwards, connecting link is equipped with in the lower end of pole, ruby gauge head is equipped with in the lower end of connecting link, be integrally formed structure, connecting link periphery wall is installed with protection sleeve, the edge of panel raises up, forming panel upper surface is groove-like structure, panel have along the uniform multiple decoration hole raised up of panel circumferential array, decoration hole is cascaded by rib through projection between decoration hole successively, central recess is formed in the upper surface middle part of panel, the retro-reflective target one being inlaid in panel upper surface is had inside each drift angle of panel, central recess place is embedded with retro-reflective target two, pole is embedded with retro-reflective target three (not shown in FIG.).
The utility model structure is simple, easy to process, keep in repair convenient, appearance looks elegant, easily regularly replaces maintenance, avoids the unpredictability that this kind of electronic component of LED damages.
Accompanying drawing explanation
Fig. 1 is structural perspective of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Provided by Fig. 1-Fig. 2, the utility model comprises panel and pole, the central vertical of panel 1 is equipped with pole 2 downwards, connecting link 3 is equipped with in the lower end of pole, ruby gauge head 4 is equipped with in the lower end of connecting link, be integrally formed structure, connecting link periphery wall is installed with protection sleeve 5, the edge of panel raises up, forming panel upper surface is groove-like structure, panel have along the uniform multiple decoration hole 6 raised up of panel circumferential array, decoration hole is cascaded by rib 7 through projection between decoration hole successively, central recess 8 is formed in the upper surface middle part of panel, the retro-reflective target 1 being inlaid in panel upper surface is had inside each drift angle of panel, central recess place is embedded with retro-reflective target 2 10, pole is embedded with retro-reflective target three.
The regular hexagon that described panel 1 is made for aluminium alloy, decoration hole is placed in inside each limit of panel, and decoration hole quantity is identical with the quantity of panel edges.
Described ruby gauge head 4 is the spheroidal be made up of ruby.
Described decoration hole 6 is that minor face is inside, the isosceles trapezoid that long limit is outside.
The lower end of described pole 2 is inversed taper platform shape, and the upper surface of inversed taper platform is identical with the upper end face size shape of pole, and the lower surface of inversed taper platform is identical with the upper surface size shape of connecting link.
