Method for visually representing scanning data, which are composed of a multiplicity of individual measurement data. The individual measurement data in each case have at least one measurement value that is linked to a respective measurement direction, wherein the measurement directions are different from one another such that a predetermined scanning region with a predetermined scanning resolution is covered. The representation of the scanning data is effected by way of an image map with a number of map points that is dependent on a predetermined display resolution and by way of an assignment rule for assigning measurement value to map point, wherein the assignment is effected immediately on the basis of the respective measurement direction that is linked to the measurement value.

A method including: recording a first image of a first field region; automatically treating a plant within the first region in-situ based on the first image; automatically verifying the plant treatment with a second image of the first region; and automatically treating a second region concurrently with treatment verification.

A combined metrology method is provided for calculating the distance, the roll and pitch attitudes, and the relative orientations between two undersea points of interest. The method comprises positioning on the sea bottom a long-range acoustic positioning system having acoustic beacons, calibrating the system in order to determine the positions of the beacons relative to one another, deploying a vehicle on the sea bottom, taking a plurality of scenes around each point of interest in order to acquire point clouds, and processing the point clouds in order to calculate the coordinates of points in a common reference frame defined by the array of beacons and centered on the position of one of the acoustic beacons.

An example method for determining a mobile device position and orientation is provided. The method may include capturing a two-dimensional image of a surface including at least four markers, and determining a unit direction vector for each of the at least four markers based on an association between a pixel location of each of the at least four markers in the two-dimensional image. The method may further include determining apex angles between each pair of the unit direction vectors, and determining marker distances from the imaging sensor to each of the at least four markers via a first iterative process based on the apex angles. Additionally, the method may include determining the mobile device position with respect to the coordinate frame via a second iterative process based on the marker distances, the apex angles, and the coordinates of each of the at least four markers.

A system and method of detecting subsurface karst features includes receiving surface mapping data. A potential surface pad location can be identified in view of the surface mapping data. A resistivity survey for the potential surface pad location can be designed. The resistivity survey can include at least one long line extending through a surface hole for each of one or more wellbores in the potential surface pad location, and a short line extending through the surface hole of one of the one or more wellbores, each short line intersecting the long line substantially at the surface hole of one of the one or more wellbores. High resistivity areas exceeding approximately 150 Ohm per meter can be identified as sub surface karst features within the resistivity survey.

A fence post layout system and method includes a measurement device to collect data corresponding to a length of a fence run and presenting a visual representation of the length of the fence run to an operator through a user interface. The measurement device also collects data corresponding to installation site characteristics, such as topography. The system analyzes the installation site data to determine fence post spacing and fence post installation locations along the fence run and outputs a visual representation to the operation of the fence post installation locations via the user interface.

A method for planning sample points for surveying and mapping is disclosed, which includes: acquiring a reference photographing location point corresponding to a region to be surveyed and mapped, and establishing a mapping relation between one shooting point in a combined shooting point set and the reference photographing location point; determining a plurality of auxiliary photographing location points corresponding to the reference photographing location point based on the mapping relation preset relative positional relations between the shooting points in the combined shooting point set; and using the reference photographing location point and the plurality of auxiliary photographing location points as sample points for surveying and mapping based on which an unmanned aerial vehicle for surveying and mapping performs surveying and mapping in the region to be surveyed and mapped. An apparatus for planning sample points for surveying and mapping, a control terminal, and a storage medium are also disclosed.
