Description
Technical field
The present invention relates to the power engineering field of measuring technique, particularly a kind of have the coding integrated landform measuring method of RTK-GPS total powerstation and a system.
Background technology
In the at present domestic map surveying technology, general method has two kinds, and a kind of is to adopt total powerstation topographic mapping landform, atural object, and another kind is RTK-GPS(Real-Time Kinematic GPS, dynamically RTK GPS) metering system.
The topographic main method of total powerstation, all detail points of field data acquisition and drafting operation, surveyor calculates all measuring point coordinates of total powerstation, on figure (generally, take AutoCAD as platform) all measuring points of plotting, according to field sketch, in a large amount of detail points, search the measuring point in the sketch, all measuring points that connect one by one each atural object form the topomap sketch.Work pattern and the total powerstation of RTK-GPS are similar, namely observe all detail points, skeletonizing, connect one by one all atural object measuring points according to sketch, form the topomap sketch, sketch with total powerstation and RTK-GPS observation is spliced to form the sketch full figure at last, and ornamenting forms the topomap finished product.The synoptic diagram of using the map surveying scheme of total powerstation mapping in the prior art has been shown among Fig. 1.
In the prior art, most of units are when carrying out topography mapping, all be to use total powerstation to measure, it is less to use the survey the topography unit of figure of RTK-GPS, even if use, also be very simple, and usually just use a kind of measurement the among total powerstation, the RTK-GPS, this greatly reduces the efficient of map surveying.Use this two kinds of mapping modes, field operation is responsible for image data, skeletonizing, and interior industry only is responsible for data are processed, the operation of interior industry, field operation disconnects mutually, in addition, how atural object connects can only rely on outdoor workers manually to draw the atural object sketch, needs the labor intensive resource, correspondingly, when surveyor carries out the data processing, need to contrast all measuring points that field sketch is manually searched each atural object in hundreds and thousands of measuring points on the same day, then line is carried out in pointwise, workload is huge, very easily makes mistakes.
On the other hand, CASS software (a kind of digital topography map Survey Software, by the research and development of southern numeral science and technology company limited) be the most widely software that use in domestic topography mapping field, most units all adopt this software terrain map of survey and drawing, yet this mapping software is the data processing Become the picture software, when carrying out the processing of geography data, can only simply use CASS software measuring point is drawn on the figure, manually connect measuring point again, efficient is very low.

The invention described above scheme, form efficient topographical surveying of Total Station RTK-GPS and line project and measured work pattern, it has not only formulated total powerstation, RTK-GPS fieldwork observation coding, fieldwork observation method, and provide unified mode of operation, and special column foot topomap has designed specific interface setting in measuring for line project, formed the total solution of total powerstation, RTK-GPS Data Format Transform, in topographical surveying, be widely used, be with a wide range of applications, can reach following beneficial effect:
One, atural object are code standardized
Gather characteristics according to RTK-GPS and total powerstation field data, innovation has been formulated field data and has been gathered the atural object coding standard, this coding not only can record the measuring point information of atural object, and can record the attribute such as direction, the number of plies, material of atural object, field operation need not skeletonizing, record atural object attribute etc., standardized RTK-GPS and total powerstation field data collecting work pattern.
Two, easily from customization
Atural object is code standardized to be the coding method of having formulated RTK-GPS and the data acquisition of total powerstation field operation atural object, but specifically the coding of each atural object can customize according to user's custom, system provides flexibly, and coding customizes function certainly, therefore the user only needs to formulate according to coding standard the field operation atural object coding of custom, and do not need to remember unfamiliar coding, increase the dirigibility that field data gathers, made things convenient for the outdoor workers operation, greatly improved operating efficiency.
Three, field data collection standardization
According to unified atural object coding, atural object observation procedure, the data acquisition of the outdoor workers that standardized has guaranteed the quality of outdoor workers data acquisition to have reduced the probability that image data is made mistakes; Do not need artificial skeletonizing, reduced the human resources input, and improved the work efficiency of field data acquisition; Guaranteed construction quality from the data acquisition source.
Four, data processing software is integrated
Atural object with standard is encoded to main line, connected the intermediate link of field data collection and data processing, according to this atural object coding standard, atural object observation procedure, CASS atural object coding standard, research and development coding RTK-GPS total powerstation integrated landform measuring system arranged, in data processing, can automatically construct the data structure of each atural object, calculate, process the observation data of various atural objects, automatically generate some data file and the coding boot files of southern CASS software, use this most widely used Software Create topomap.
Five, interior field operation work efficiency improves, and construction quality guarantees
The operational method of total powerstation in topographical surveying is very ripe, all using in each unit, but but in topographical surveying, RTK-GPS can be observed the work standardizations such as various complicated atural objects without any one of a unit formation, formulate the field operation coding standard, and form normalized fieldwork observation pattern, data processing is according to coding standard, need not the field operation skeletonizing, full-automatic topographic mapping, line project column foot topomap, with real a whole set of solution from field operation to interior industry that forms integrated topographic mapping of Total Station, particularly blank especially for the easily column foot map surveying specialty solution of aerial power transmission line, the present invention program has really formed the operational method of the integrated landform mapping of RTK-GPS associating total powerstation, has greatly improved topographic operating flexibility and efficient.
Six, achievement versatility
South CASS topomap Become the picture software is the topomap Become the picture software that is most widely used of field, domestic project construction field of domestic topographical surveying, the present invention program has realized the integrated CASS interface of RTK-GPS associating total powerstation, use CASS and generate the topomap finished product, guaranteed the versatility of topomap finished product.
Above-described embodiments of the present invention only are the detailed descriptions to a preferred embodiment of the present invention, do not consist of the restriction to protection domain of the present invention.Any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
