发明名称 Device for mapping equations of medium plane at exterior of building, has electronic bearing compass establishing angular position of laser rangefinder and controlling position and orientation of device in station installing phase
摘要 <p>The device has a laser rangefinder that is articulated around a fixed rotation point (PtRef) and controlled by operator along two degrees of freedom. An electronic bearing compass establishes angular position of the laser rangefinder cyclically in terrestrial absolute mark by using a magnetic sensor and a gravity sensor (14). The electronic bearing compass controls the position and orientation of the device in station installing phase.</p>
