摘要： The invention relates to a surveying pole (1) and to a secondary sensor unit (2) which is attachable to the surveying pole (1). A reflector (10) and/or GNSS receiver attachable to the surveying pole (1) can be attached independently of whether or not the secondary sensor unit (2) is attached to the surveying pole (1). A distance between the reflector (10) and/or GNSS receiver and a pole tip (12) is also independent of whether or not the secondary sensor unit (2) is attached to the surveying pole (1). A distance between an attached reflector (10) and/or GNSS receiver and the attached secondary sensor unit (2) is also known and fixed. The invention also relates to a method and computer program product for numerically correcting distance measurement errors due to reflector (10) orientation and position with respect to a primary sensor (14), in particular a tachymeter.

摘要： The invention relates to survey instrument (4) comprising a single point and a point cloud measuring functionality, a communication interface (81,82), and a computing unit (30). The point cloud measuring functionality configured to emit a scanning beam (21) along a first measuring axis and to advance the first measuring axis along a scanning pattern. The point cloud measuring functionality is configured to generate point cloud data representing a setting (2). The single point measuring functionality is configured to emit a measuring beam (11) along a second measuring axis. The first measuring axis is referenced to the second measuring axis. The communication interface (81,82) is configured to receive model data representing at least a part of the setting (2) and comprising referencing data to an external coordinate system. The computing unit (30) is configured to identify cardinal features in the point cloud data as well as in the model data. The survey instrument (4) is configured to execute a stationing functionality by merging the acquired point cloud data with the model data by matching the identified cardinal features in the point cloud data with respective cardinal features in the model data.

摘要： The invention relates to identification of a target of a geodetic system based on global and local identification references. The target comprises a light emitter (LE) configured for emitting any of n predetermined modulated light patterns (MLPs), being permanently assigned to one of m (m > n) global identification reference (GIR), e.g. a Bluetooth address. The target is configured for transmitting and/or receiving data based on the GIR to which it is assigned. The geodetic system further comprises a geodetic surveying instrument such as a total station comprising an optical sensor (OS) configured for receiving the MLPs and digitizing them by a fast sampling analogue-to-digital converter (ADC). Further, a computing system as part of the geodetic system selects one of the at least one targets or receives a selection of one of the at least one target, the selected target being assigned to a selected GIR. One of n local identification references (LIRs) is temporarily assigned to the selected GIR. The light emitter of the selected target is directed to emit an MLP corresponding with the assigned LIR. Thus, by detection of the assigned LIR, the selected target is identified.
