Abstract
The utility model discloses a three-dimensional laser scanner suitable for mountainous areas on karst plateaus with weak GPS signals. The laser scanner comprises a scanner (1), a laser transmitting and receiving device (4) and a tripod (5). An RTK receiver (2) and a connection shaft (3) are installed above the scanner (1) which is fixedly installed on the tripod (5). The RTK receiver (2) is connected to the upper end of the connection shaft (3), and the laser transmitting and receiving device (4) is connected to the lower end of the connection shaft (3). The laser scanner solves the problem that in the complex and diverse environment of high-altitude mountainous areas on karst plateaus, a GPS signal receiver contained by a conventional three-dimensional laser scanner cannot receive GPS signals stably or receives shifted GPS coordinates sometimes. The laser scanner ensures the precision of large landscape scanning and can be widely used in works such as field measurements of mountainous areas on karst plateaus with the laser scanner.
Description
Technical field
The utility model relates to a kind of three-dimensional laser scanner, particularly a kind of three-dimensional laser scanner that is applicable to the weak area use of the gps signals such as karst plateau mountain region, basin, valley.
Background technology
Three-dimensional laser scanning technique is latest developments a kind of new technologies rapidly, on a large scale, the geography information of the high precision Real-time Obtaining of digital elevation model, city reconstructing three-dimensional model, regional area the aspect such as is obtained and is shown powerful advantage, has become an important supplement of Photogrammetry and Remote Sensing technology.Existing three-dimensional laser scanner conventionally adopts instrument to carry gps receiver and obtains geographic coordinate information, lay and control net and carry out three-dimensional modeling, yet in karst plateau mountain area, peak cluster depression, the geomorphic types such as peak cluster the lowest point are complicated, height above sea level is higher, and cloudy layer blocks, microclimate type is complicated and changeable, cause this area's gps signal to receive compared with other area difficulties, three-dimensional laser scanner carries gps signal receiving equipment and under some environmental factor and condition element, often there will be gps signal to accept situation unstable or gps coordinate skew, when carrying out large scene scanning, the for example three-dimensional mapping of section, while drawing large scale topographical map, often because the accumulation of gps coordinate error, can cause larger measuring error, be difficult to meet the needs that field operation is measured.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of three-dimensional laser scanner that is applicable to the weak mountain area of karst plateau gps signal, this instrument can be brought up to centimetre-sized by its GPS positioning precision, greatly reduce measuring error, thereby make up the deficiencies in the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of three-dimensional laser scanner that is applicable to the weak mountain area of karst plateau gps signal.Its formation comprises Laser emission and receiving trap, scanner and tripod, and RTK receiving trap and coupling shaft are installed above described scanner, and scanner is fixedly mounted on tripod; The upper end of coupling shaft connects RTK receiving trap, and the lower end of coupling shaft connects Laser emission and receiving trap.
The above-mentioned three-dimensional laser scanner that is applicable to the weak mountain area of karst plateau gps signal, also comprises power supply support equipment and notebook computer, and power supply support equipment connects scanner by power lead, and notebook computer connects scanner by data line.
The beneficial effects of the utility model: compared with prior art, the utility model is the improvement to conventional three-dimensional laser scanner on prior art basis, by installing based on RTK (real-time dynamic positioning: GPS receiving trap Real-TimeKinematic) above scanner, can better in the weak mountain area of karst plateau signal, carry out gps coordinate location than existing three-dimensional laser scanner, having solved conventional three-dimensional laser scanner carries gps signal receiving equipment and under the environment of the complicated and diversified Karst Mountain Areas of high height above sea level, occurs that gps signal accepts the drawback of poor stability or gps coordinate skew, precision while having guaranteed to carry out large scene scanning, can be widely used in the work such as field operation measurement of karst plateau mountain area three-dimensional laser scanner.
