DETAILED DESCRIPTION OF THE FIGURES ACCORDING TO THE FIRST ASPECT OF THE INVENTION
[0664] FIG. 1 shows on the left side a typical mobile control device 3 having a touch sensitive display. The touch sensitive display is configured to receive touch inputs, for example, stroke based touch inputs 8 and to display a view of the physical environment 2 in a live view 7. Thereby, the view of the physical environment 2 is generated based on environment data, which are received from at least one sensor module of the UAV 1. The sensor module typically relates to a camera of a camera system of the UAV 1.
[0665] The mobile control device 3 is configured to control the flight and operation of a UAV 1. Therefore, a communicative connection between the mobile control device and the UAV is established. Touch inputs, which are received by the touch sensitive display, are typically indicative of moving the UAV 1 in the physical environment 2.
[0666] The UAV 1 includes a directional distance measuring module as sensor module. The directional distance measuring module is configured to measure distances and directions to surfaces/points on surfaces of the physical environment 2. Directions can be measured, for example, by determining a horizontal and vertical angle under which a distance measurement radiation is emitted towards a surface/point on a surface of the physical environment 2. A distance can be measured, for example, based on the time-of-flight principle using the emitted distance measurement radiation.
[0667] Measuring surfaces/point of surfaces of the physical environment 2 enables measuring/surveying physical environments and objects in the physical environments. Physical environments 2 can relate, for example, to landscapes, acres, fields, forests, hillsides etc. Objects can relate, for example, to buildings, roads, bridges, humans, airplanes, objects of a construction site, tunnels etc.
[0668] Measuring/surveying physical environments 2 and objects in the physical environments relates to generating and recording measurement data, which enable a digital reconstruction of the measured/surveyed physical environment and/or objects. Such measurement data typically relate to 3D point cloud data, which enable the reconstruction in the form of a 3D point cloud.
[0669] The distance measuring module has a field of view, wherein physical environments 2 and objects, which are within the field of view, are measurable. The field of view has a main view direction 4. For a specific, for example optimized, measuring/surveying of physical environments 2 and objects, the field of view with its main view direction is aligned in a predefined way to the physical environment 2 or to an object, which is to be measured/surveyed. Thereby the alignment of the field of view of the distance measuring module is controlled by controlling the movement of the UAV 1.
[0670] FIG. 1 shows on the right side the UAV 1, which is flying in the physical environment 2. The UAV 1 is in front of a building with its distance measuring module facing the building. Thereby, the building is the object to be measured/surveyed. The faade of the building is the object surface 6. At least a part of the faade 5 is within the field of view of the distance measuring module. This at least a part of the faade 5 can be determined by measuring/surveying.
[0671] As shown in FIG. 2, if the touch sensitive display receives, within the constant distance mode/the constant distance mode being activated, a stroke-based touch input 8, the UAV 1 is positioning and orienting itself such, that the main view direction 4 of the distance measuring unit is aligned in a specific/predetermined way 10 with respect to the at least a part of the faade. Furthermore, the UAV 1 moves along the faade and maintains during moving a constant distance 11 to the faade and the specific/predetermined alignment with respect to the faade.
[0672] It can be provided that the UAV 1 is moving only as long as the stroke-based touch input 8 is being received. With other words, as soon as a touching, related to the stroke-based touch input 8, of the touch sensitive display is interrupted or terminated the UAV 1 is stopped.
[0673] FIG. 3 shows a stroke-based touch input 8. The touch sensitive display is touched by a finger, whereinwhile maintaining touching the touch sensitive display with the fingerthe finger is stroked across the touch sensitive display. Stroking across the touch sensitive display relates to generating the stroke progression 9.
[0674] The stroke-based touch input 8 can also relate to touching the touch sensitive display with two fingers in analogy to touching the touch sensitive display with one finger.
[0675] The movement of UAV 1 along the faadewhile maintaining during moving a constant distance 11 to the faade and the specific/predetermined alignment with respect to the faadeis further based on the stroke progression 9. Based on the stroke progression 9 control commands can be derived for controlling the movement of the UAV 1. A control command can relate to, for example, a stroke direction 14, in which the UAV 1 moves along the faade, a velocity with which the UAV 1 moves along the faade etc.
[0676] The stroke-based touch input 8, shown in FIG. 3, includes a stroke progression start state 12 and a stroke progression end state 13. It can be provided that between the stroke progression start state 12 and the stroke progression end state 13 a plurality of further stroke progression start states 12 and stroke progression end states 13 are included, which ad up to the stroke-based touch input 8 and can be used to derive, for example, the stroke progression 9 and, based thereon, control commands for controlling the movement of the UAV 1 during receiving the stroke-based touch input 8.
[0677] It can be provided, that a selectability of the constant distance mode is provided to a user. The selectability of the constant distance mode can be based on a selectability of the at least a part of the faade 5 which is determined by the UAV 1. For example, the at least a part of the faade is captured by the distance measuring module of the UAV 1. As soon as the at least a part of the faade is determined its selectability by touching the determined at least a part of the faade can be provided. If the determined at least a part of the faade is selected/touched, the constant distance mode can automatically be activated or a selectability of the constant distance mode can be provided to a user.
[0678] A selectability of the constant distance mode can also be triggered by, for example, geometric properties of the at least a part of the faade 5. For example, if the faade is the faade of a lighthouse, the faade is curved. Without moving, only a small part of the faade will be capturable by the distance measuring module. Based on a determined curvature of the at least a part of the faade the constant distance mode can be selectable or automatically activated.
[0679] A geometric property of the faade can also relate to a discontinuity along the faade. A discontinuity can relate, for example, to a corner, which includes an abrupt direction-change in the course of the faade.
[0680] A selectability of the constant distance mode can be provided, for example, by overlaying a symbol such as a ruler or distance indicator to the determined at least a part of the faade 5.
[0681] FIG. 4 shows a top view to a UAV 1, having a body 15 with a front end 16 and a back end 17. The directional distance measuring module is integrated in the front end 16 of the UAV 1. The UAV 1 includes a front 19 and side 22 cameras, which are arranged at locations, where the shrouding of the UAV 1 is connecting to strut elements of the mounting structures. On the upper side, with respect to a flying position, a top camera 20 is arranged on the body 15. On the bottom side, with respect to a flying position, a bottom camera 21 is arranged on the body 15. Each camera has a field of view 18 with a fixed orientation in relation to the UAV 1. The UAV 1 further has four propulsion units realized in form of rotary wing/propeller units. Two propulsion units are arranged on a left side and on a right side of the body 15.

DETAILED DESCRIPTION OF THE FIGURES ACCORDING TO THE EIGHTH ASPECT OF THE INVENTION
[0731] FIG. 28 shows a flying UAV 1, which is powered by a single battery 43. While flying the UAV is continuously providing battery charge level information 42, related to the battery 43, either to a computing unit of the UAV or to a mobile control device 3 for determining a most recent battery charge level 44. The mobile control device 3 has a touch sensitive display and displays a charge level notification 45 to a user of the UAV 1 based on the battery charge level 44.
[0732] In case the battery charge level 44 is determined to be at a level, which necessitates swapping the battery 43, the UAV 1 is instructed to autonomously move to a predetermined location. The location can be, for example, the location, from where the UAV has taken off/been launched, or the location from where a user is controlling the UAV. The UAV then is further instructed to land at the location, such that the battery 43 can be replaced within a predetermined time window. The predetermined time window is strongly depending on the amount of time during which the UAV can be powered by capacitor power. The predetermined time window is as well depending on which and how many of the power consuming units of the UAV have to be supplied by capacitor power during replacing/swapping the batteries.
[0733] After the UAV has landed at the location, typically the propulsion units, the cameras 19, 20, 21, 22, or at least one of the cameras and at least the most power consuming sensor module, for example, the directional distance measuring module, are deactivated.
[0734] At the latest, when the battery is being disconnected from the UAV the UAV switches from the battery powered supply mode to the capacitor powered supply mode, such that an uninterrupted power supply is provided.
[0735] After the battery has been replaced with a fully charged battery, the UAV can provide an operability, which relates to the UAV autonomously moving back to the location, where it was before returning to the location for replacing the battery. For example, if the UAV has been on a flight-mission for inspecting/surveying/measuring/digitizing the UAV's environment, the UAV can provide for an operability, which makes the UAV to autonomously continue the flight-mission after the battery has been replaced.
[0736] After the battery has been replaced with a fully charged battery, the UAV can provide an operability, which relates to the UAV automatically transmitting recorded flight data to a storage, for example, a cloud storage, or to the mobile control device.
[0737] The recorded flight data can relate to, for example, sensor data relating to inspecting/surveying/measuring/digitizing the UAV's environment.
