METHOD OF HARMONIZATION OF THE LINE OF SIGHT OF OPTICAL DEVICE WITH A LONGITUDINAL AXLE OF LAND VEHICLE Russian patent published in 2018 - IPC G01C21/00 

FIELD: measurement.

SUBSTANCE: invention relates to measuring methods, namely to methods for correcting angular parameters determined by a topographical reference and navigation system of a land vehicle, for their consideration in the process of survey measurements. Method of aligning the axes of the line of sight of the optical device with the longitudinal axis of the land vehicle is that the vehicle is installed on the alignment section, the sighting device is leveled, its zero readings are set when it is placed on the crosshairs of the alignment target, the azimuth is determined, the initial corrections to the angular readings for their input into the software and hardware complex of the land vehicle are calculated. After the installation of the land vehicle on the alignment section, its centres are determined on the chassis of the vehicle and marked by risks, on which the plumb lines are placed so that the threads of loads are located in the same plane with the longitudinal axis of the land vehicle. If this condition is not met, the chassis is hung using lifting devices to align the plumb lines with the plane, the alignment target is set so that the vertical plane passing through the axis of symmetry of the land vehicle coincides with the axis of symmetry of the lines of guidance of its longitudinal axis on the alignment target, the vertical position of the alignment target is set according to a plumb, its installation height is determined by the specified size of the sighting device on the land vehicle, the target is set up using a periscopic artillery boot, further, the inertial navigation system is tied to the zero reference point as the determination of the initial correction of the azimuth angle determined by means of an optical sight for its recording in the special software of the hardware and software complex.

EFFECT: technical result consists in forming a method for coordinating the axes of the line of sight of the optical instrument with the longitudinal axis of the land vehicle, ensuring the parallelism of the zero line of sight of the optical device with zero setting of the angle scales with respect to the longitudinal axis of the land vehicle equipped with a topographic reference and navigation system.
