PORTABLE GEODESIC RECEIVER (OPTIONS) AND METHOD FOR OBTAINMENT OF GEODESIC DATA Russian patent published in 2022 - IPC G01S11/02 G01S17/06 

FIELD: engineering geodesy.

SUBSTANCE: group of inventions relates to the field of engineering geodesy, namely to devices and methods intended for geodesic measurements. Using an inertial system of a digital mobile device, a position of a geodesic receiver is aligned. Then, video recording or a series of photos of the terrain is taken using a camera of the geodesic receiver, when moving along the specified trajectory. In addition, a height of the position of the geodesic receiver is measured using a height measurement node containing a laser rangefinder, an optical axis of which is combined with an optical axis of a camera of the digital mobile device. Obtained data is transmitted to a processor of the geodesic receiver. Taking into account obtained data on the height of the position of the geodesic receiver, as well as data from the inertial system, data from the camera of the geodesic receiver is processed. Then, a three-dimensional model of the terrain is formed to obtain required parameters of the specified terrain objects.

EFFECT: increase in the convenience of geodesic measurements by one operator, as well as increase in the accuracy of geodesic measurements.
