Abstract
The utility model provides a multifunctional laser range finder. The multifunctional laser range finder comprises a geographic position sensor, a pitch angle sensor and a horizontal angle sensor, wherein the geographic position sensor, the pitch angle sensor and the horizontal angle sensor are connected with the multifunctional laser range finder through interfaces. The geographic position sensor is one of GPS (Global Position System) or a satellite positioning module; the pitch angle sensor is one of a two-axis acceleration sensor or a three-axis acceleration sensor; and the horizontal angle sensor is a geomagnetic sensor. By adopting the multifunctional laser range finder, a problem that a traditional laser range finder is unable to measure in an intricate environment or the measurement result is inaccurate is solved. The multifunctional laser range finder adopting three sensors can be used for precisely measuring the indirect horizontal distance, the indirect vertical distance and the measurement space position, the use is convenient and the market prospect is broad.
