Along with the development and progression of photogrammetric technology, and the fast lifting of the universal and performance of digital camera, amateur digital camera photogrammetric survey method, is widely used in fields such as Construction of Civil Engineering monitoring and scientific experimentations.Photogrammetric survey method has noncontact, equipment is simple, low to environmental requirement, automaticity is high, data acquisition, data processing speed is fast, precision is high, obtain image information can preserve for a long time, duplicate measurements, can reproduce the advantage that construction and experimentation etc. are unique.The technical method that the object space of digital camera digital close range photogrammetry controls is one of gordian technique of close-range photogrammetry application.
The application of digital close range photogrammetry in civil engineering work, except obtaining the three-dimensional coordinate of measured target, is more monitoring relative position, displacement etc.Such as, in constructing tunnel, excavate the convergent deformation of transversal section, Vault settlement, the linear measurement in bridge construction, the monitoring of deflection deformation, the subgrade settlement in high-speed railway, rail smooth detection etc.Relation control is applied very general in close-range photogrammetry.
At present, the object space of digital close range photogrammetry controls common method to be had, lay artificial target, employing activity controls support, scale etc. with scale graduation, these methods have certain difficulty, not portable in practical application and operation, lay manual control point or in-site installation controls support poor in timeliness etc.
Summary of the invention
(1) technical matters that will solve
For solving the problem, the utility model proposes a kind of noncontact monitoring measurement and controlling flag-rod, which overcome on measured target or periphery cannot lay the difficult problem at fixing reference mark, improve the application efficiency of photogrammetric survey method.
(2) technical scheme
A kind of noncontact monitoring measurement controls flag-rod, it is characterized in that: comprise the telescopic movable Sopwith staff of 5 joint, and often save chi and be about 1 meter, overall length is 5 meters; Sopwith staff front vertical direction is delineated spacing not 20 centimetres of grade or the photogrammetric proprietary monumented point of 30 centimetres, and the spacing of monumented point is known determined value; Monumented point shape is a capable shape of little funnel of a positive trigonometric sum inverted triangle composition, and monumented point size is 4 × 4cm.
Further, described Sopwith staff has mark lines, and the thickness of described mark lines divides Three Estate, and thickness grade is determined according to the requirement of measurement accuracy and different photographic scale; Monumented point center on Sopwith staff vertical direction is strictly located on the same line.
Further, described Sopwith staff top is equipped with can suspender, and leveling circle level is equipped with at the middle part of Sopwith staff, and annex has support tripod.
Further, described Sopwith staff is provided with telescopic buckle between joint and joint, and the outside of telescopic buckle is provided with folding pin, and one end rivet of pin is on buckle, and the other end is connected on buckle by magnet; When by the second section of Sopwith staff, Section of three pull-out, telescopic buckle automatic spring, opens the folding pin be attached on buckle and fastens next joint Sopwith staff, even if buckle loosens using a joint Sopwith staff and also can not glide due to pin like this.
(3) beneficial effect
The utility model compared with prior art, it has following beneficial effect: a kind of noncontact monitoring measurement of the present utility model controls flag-rod, easy to carry, simple and quick, be applicable to multiple environment, and when follow-up data acquisition and procession, be conducive to automation collection data (using robot measurement target identification technology), accuracy of data acquisition high.Multiple environment can be adapted to, easy and simple to handle, improve measuring speed, little to construction interference in Construction of Civil Engineering monitoring, a large amount of field process is transferred to interior industry and completes, labour intensity is low, can increase work efficiency, the application promoting digital close range photogrammetry is had great significance.
