Improvement of optimization of the drive design for laser scanners based on the analysis of characteristics of scanning devices in construction industry

A laser scanning is a promising method of control in construction, providing high accuracy and speed of measurements. Terrestrial laser scanning is one of the key tools within the framework of Building Information Modeling technology, enabling the acquisition of precise data regarding the size, position, and deviation of objects. The article analyzes various areas of application of terrestrial laser scanning in construction and determines priority requirements for the technical specifications of the equipment. The significant role of the drive system in ensuring high angular accuracy of scanning is emphasized. An analysis of existing laser scanning systems is conducted, focusing on the technical features of drive designs that ensure high angular precision, and the main directions for further improvement of drive systems are determined. The possibility of applying electric drive control systems based on Phase-Locked Loop technology to reduce scanning costs without reducing angular accuracy through the optimization of electric drive design is considered.It is clarified how the improvement of electric drives can facilitate the wider application of terrestrial laser scanning in construction.
