INSTALLATION METHOD OF MEASURING INSTRUMENT TO WORKING POSITION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC G01C3/00 

FIELD: instrument making.

SUBSTANCE: installation method of measuring instrument to working position at fixed point of locality involves preliminary and final alignment and levelling of measuring instrument, selection of false grid system, measurement of alignment error and reduction of values considering alignment error. Collimation plane of measuring instrument is oriented as per direction of linear element of alignment error, value of direction and value of image of linear element of alignment error is recorded and actual value of linear element of error is calculated. Measurements provided with purpose of measuring instrument are made, coordinates of fixed and collimating points are calculated and the determined values provided with the purpose of instrument are calculated considering alignment error value. Installation device of measuring instrument to working position at fixed point of locality includes imaging system, sensor for measurement of alignment error, electronic information recording and processing system. Imaging system is equipped with electromagnetic radiation source and sensor of position of centre of identification spot from electromagnetic radiation source. Electronic information recording and processing system is made in the form of complex of functional units connected to each other in compliance with the specified algorithm of reduction of measured values provided with purpose of measuring instrument, considering alignment error, and the above system is installed so that it can receive signals from the above sensor of position of centre of identification spot.

EFFECT: high accuracy degree of required precision and high-precision measurements in constraint environment.
