  • Patent number: 9377301
    Abstract: A mobile field controller, together with a geodetic surveying device, forms a one-person measurement system for geodetic position determination. The field controller allows the spatial orientation of the field controller to be determined. The field controller supports a geodetic target object and has a distance-measuring unit that measures the distance between the field controller and a target point, the distance being optically marked by the field controller, as a result of which a 3D point cloud is generated without physical contact to a target point. When surveying a specific terrain region, algorithms analyzing the 3D point cloud are saved in a control and evaluation unit of the field controller. The absolute position of the target point is calculated from the data of the spatial orientation of the field controller, the distance between field controller and target point and the absolute position of the geodetic target object.
