Unmanned autonomous vehicle (UAV) selection information identifying a UAV, flight path information, and a relative elevation difference value that is a difference between a first elevation value of a start location and a second elevation value of a drop location are received. Navigation of the UAV is initiated using the UAV selection information and the flight path information. A relative altitude difference value is obtained using a first altitude value of the UAV associated with the start location and a second altitude value of the UAV associated with the drop location. In response to a difference between the relative elevation difference value and the relative altitude difference value being outside a predefined threshold, UAV is caused to adjust the second altitude value such that an updated difference between the relative elevation difference value and an updated relative altitude difference value is within the predefined threshold.

Measurement method where a code projection which is dependent on a three-dimensional position of a code carrier relative to a sensor arrangement is generated on a sensor arrangement, and at least part of the code projection is captured. An angular position of the code carrier with reference to the defined axis of rotation is ascertained and a current measurement position of the measurement component relative to a base is determined, wherein, a position value for at least one further degree of freedom of the code carrier relative to the sensor arrangement is ascertained on the basis of the code projection and is taken into account to determine the current measurement position, and a relative position of the connecting element with respect to the holder and/or the deformation thereof is determined from the position value in the form of a change in shape or size.

A method of creating a privacy mask from an image imaged by an imaging device in which a rotation axis of a camera and a center of a lens do not match includes measuring a distance from the camera to an object in a first imaging condition; creating a first mask for the object, and storing the distance together with the first mask; and creating a second mask for the object in a second imaging condition and correcting a position of the second mask using the first mask and the distance, wherein an imaging angle of the camera in the first imaging condition is same as the imaging angle of the camera in the second imaging condition, and wherein a position of the lens in the first imaging condition is reversed around the rotation axis from a position of the lens in the second imaging condition.

Methods, systems, and computer code on computer-readable media are provided that are directed to generating area skyline data using a digital elevation or surface models (DEMs or DESs) and shadow casting techniques. Some embodiments use an area of maximum shadow line overlap, for shadow line images based on target location skyline azimuth and elevation angle data, as the best approximation for the position of the target location in an area. Some embodiments select the location showing the best fit to the target skyline azimuth and elevation angle data as the best approximation for the target location.
