Abstract

Abstract: Quality inspection and acceptance of surveying and mapping results is a very important part in the whole process of surveying and mapping production projects.The existing inspection methods mainly use total station and GNSS RTK field purchasing points, which are heavy in workload and small in number.With the continuous emergence of new technologies, traditional methods can not meet the requirements of rapid update of data and continuous improvement of accuracy.Vehicle-mounted laser scanning and measurement technology, as one of the cutting-edge technologies in modern surveying and mapping field, has fast data acquisition speed, high automation degree of data processing, intuitive data results, high-precision and strong mobility, and is very suitable for quality inspection of all kinds of surveying and mapping data results.In this paper, SSW vehicle-mounted laser modeling and measurement system is used to scan and collect data from 15 sample areas. After automatic extraction and screening of feature points, data results for inspection are obtained. Compared with the data obtained by conventional methods, the feasibility of the the technology for quality inspection is verified.

Key words: SSW vehicle mobile measurement system, feature points, automatic extraction, quality inspection
