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.

Comparative analysis of algorithms for projected laser line identification and recognition for 3d scanning devices

This paper is devoted to the comparative analysis of algorithms for identification and recognition of the projected laser line. The principles of these methods, their negative and positive aspects and the possibilities of their implementation for 3D-scanning devices are described. Algorithms approbation was conducted on experimental setup using C++ programming language and OpenCV library. It is shown that, depending on the image size and details of the input image, one or another algorithm should be applied

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.
