COMPARATIVE ANALYSIS OF ALGORITHMS FOR LASER LINE IDENTIFICATION FOR 3D SCANNING DEVICES

A comparative analysis of algorithms for laser line center determination and recognition has been conducted. The issues in this area are described, outlining the principles, pros, and cons of each method. Additionally, the possibilities of their application using programming code are demonstrated. Algorithm testing was performed using Python language tools and the OpenCV library. It is shown that the quality of the result in the extremum method significantly depends on the quality of the selected parameters for the Butterworth filter.

The use of modern technology in the classical surveying

Purpose. The article presents examples of usage of modern technologies to improve classical geodetic measurements. Modern technologies such as 3d scanners or unmanned aircraft vehicles (UAV) can be applied to increase the accuracy of complex monitoring of tall and unreachable objects.  There was shown an example of measurement of the wind speed impact on the Gliwice Radio Tower deflection. The Tower is one of the oldest and highest wooden (non-impregnated) towers in Europe and because of the historical past it’s very important object in the worldwide culture.
