METHOD AND SYSTEM OF MEASUREMENT OF DISTANCE TO REMOTE OBJECTS Russian patent published in 2018 - IPC G01C3/08 

FIELD: measuring equipment.

SUBSTANCE: group of inventions refers to methods and systems for measuring distances to distant objects. Computer-implemented method for measuring distances to remote objects using a camera includes the steps of: receive data on the point of view of the remote object, geographical coordinates of the chamber and the height of its installation above the ground; at least one point of the remote object and at least one horizon point on the frame received from said camera are determined; data on the azimuth of observation are received of at least one point of the remote object, azimuth of observation of at least one horizon point and terrain data along the azimuth of object observation and azimuth of observation, at least one horizon point. On the basis of the obtained data, at least one difference in elevation angles between at least one, one point of the remote object and at least one point of the horizon; angle of the observation site is determined, at least one point of the horizon on the basis of data on the azimuth of observation, at least one horizon point, terrain relief and a given observation height; determine the angle of the observation point of the point of the remote object on the basis of the data on the angle of the observation site, at least one horizon point and a difference in elevation angles between, at least, one point of the remote object and, at least one point of the horizon defined earlier; distance to the remote object based on the data about the angle of the observation point of the remote object, terrain, azimuth of observation of a remote object and a given observation height is determined.

EFFECT: technical result is to improve the accuracy of determining the distance to remote objects.
