METHODS FOR GEOSPATIAL POSITIONING AND PORTABLE POSITIONING DEVICES THEREOF
FIG9 shows a schematic view of a portable positioning device in accordance with an embodiment
With reference to FIG9, a positioning device in accordance with another embodiment is described. FIG9 shows a portable positioning device 900 including a GNSS receiving unit 910 and a display unit 940. The portable positioning device 900 includes also a body 905 in which the processing unit (not shown) of the positioning device 900 may be arranged. Alternatively, the processing unit of the positioning device may be arranged in the same unit as the display unit, such as for example at the backside of the display unit 940. In the embodiment shown in FIG9, the body 905 is in the form of a cylinder which may be convenient to be handheld by an operator. However, other geometries and arrangements may be envisaged. In some embodiments, the element denoted 940 in FIG9 may be a smartphone including a display unit 940, a processing unit and an imaging device (not shown in this view). In the present example, the positioning device 900 may include the body 905 and a holder, or holding element (not denoted), attached to the body 905 and adapted to receive a unit including an imaging device, a display unit and a processing unit, such as e.g. a smartphone. FIG9 illustrates also embodiments of the present disclosure in which the portable positioning device may be implemented based on an existing device 940 already including a processing unit, an imaging device and, optionally, a display unit, to which a module including the GNSS receiving unit is added. Expressed differently, embodiments of the present disclosure include an add-on module only including a GNSS receiving unit with its antenna, in which the processing unit of the existing device is adapted to operate in accordance with a method as defined in any one of the preceding embodiments.

['1. A Method (1100) for determining a geospatial position of a point of interest, said method comprising: collecting (1110), by a data collector (150) of a positioning device (100), data from a global navigation satellite system, GNSS, receiving unit (110) of said positioning device and data from at least one of an imaging device (130) and an inertial measurement unit, IMU (170), of said positioning device for a plurality of positions of said positioning device in the vicinity of said point of interest; transmitting (1120), to a data fusing processor (190), said collected data for determining orientations and positions of said positioning device for said plurality of positions of said positioning device in a global coordinate system (X 1 , Y 1 , Z 1 ); obtaining (1130), by said data collector, a pointing input indicative of a position of said point of interest relative to said positioning device for at least one reference position of said positioning device; and transmitting (1140) said pointing input to the data fusing processor for identifying said point of interest and for determining (1150) said geospatial position of said point of interest in said global coordinate system based on the determined orientations and positions of the positioning device in the global coordinate system.', '4. The method of any one of the preceding claims, wherein said collected data includes GNSS data received at the GNSS receiving unit and gyroscopic and acceleration data received at the IMU for said plurality of positions.', '17. The positioning device of any one of claims 12-15, further including a display unit adapted to assist in capturing said series of images, or said video, and/or in identifying said point of interest.']
