Localization of a surveying instrument
A method for surveying an environment by a movable surveying instrument with a progressional capturing of 2D-images by at least one camera and applying a visual simultaneous location and mapping algorithm (VSLAM) or a visual inertial simultaneous location and mapping algorithm (VISLAM) with a progressional deriving of a sparse evolving point cloud of at least part of the environment, and a progressional deriving of a trajectory of movement. The method comprises a progressional matching of the sparse evolving point cloud with a previously derived 3D-geometry, with a minimizing of a function configured to model a distance between the sparse point cloud and the previously derived 3D-geometry and deriving a spatial localization and orientation of the surveying instrument. At least one surveying measurement value of the environment by a spatial measurement unit is combined with the sparse point cloud or the previously derived 3D-geometry.

An automatic leveling type geographic surveying instrument
This invention discloses an automatic leveling geographic surveying instrument, belonging to the field of geographic surveying technology. The invention first acquires the tilt angle and tilt angle change rate of the total station base in real time, dividing station settlement into three stages: micro-settlement, significant settlement, and sudden settlement. For the micro-settlement stage, real-time error compensation is achieved through elevation correction of the line-of-sight height-time fitting curve and vertical axis tilt horizontal angle correction. For the significant settlement stage, high-precision automatic leveling based on a kinematic model, physical compensation for the three-dimensional displacement of the instrument center, and orientation reset are executed sequentially. For the sudden settlement stage, shutdown alarm and abnormal data marking are implemented. This invention also includes surveying instrument hardware with electrically telescopic outriggers and a multi-sensor system, adaptable to surveying operations in complex geological conditions, balancing measurement accuracy, operational continuity, equipment safety, and data utilization.

Method and system for aligning surveying instruments
ActiveUS12625241B2Active open surveying meansElectromagnetic wave reradiationMeasuring instrumentSurvey instrument
A method for aligning two surveying instruments in a common space in a process that uses an autocollimation of a collimated light beam transmitted by a first surveying instrument and reflected by a second surveying instrument. In the alignment process, the first surveying instrument may emit a collimated light beam towards the second the surveying instrument and receive a reflection of the collimated light beam from the second surveying instrument in an autocollimator. The reflection may be generated for example by a mirror at the second surveying instrument. When the light beam is reflected such that autocollimation of the collimated light beam is achieved at the first surveying instrument, the first and second surveying instruments are in a predetermined positional relation with respect to one another. With a known predetermined positional relation between the reflecting mirror and the line of sight of the second surveying instrument, measurements by both surveying instruments can be made in a common coordinate system.
