METHODS FOR GEOSPATIAL POSITIONING AND PORTABLE POSITIONING DEVICES THEREOF

Abstract:

According to some embodiments of the present disclosure, there is provided a method and a positioning device for determining a geospatial position and a nature of an object. The method may include capturing, by an imaging device of the positioning device, at least one image of a surface. The captured image may be processed for identifying at least one candidate object in the surface and for determining a nature of the candidate object. Further, the method may include displaying the captured image with a selection mechanism for assisting in selection of the candidate object, wherein the captured image is displayed with an indication of the determined nature of the candidate object. The method may then include receiving an input via the selection mechanism for selection of at least one of the at least one candidate object. Further, the method may include collecting data from a global navigation satellite system (GNSS) receiving unit of the positioning device and data from the imaging device for a plurality of positions of the positioning device at which the selected object is viewed by the imaging device. The collected data may then be used for determining orientations and positions of the positioning device for the plurality of positions of the positioning device in a global coordinate system, followed by determining the geospatial position of the selected object in the global coordinate system based on the determined orientations and positions of the positioning device in the global coordinate system.
