作为一项新的测绘手段,三维激光扫描技术以其高速、高精度、非接触的测量特点,应用越来越广泛。从20世纪90年代的每秒1000点到如今的超过100万点,其扫描速率有了多个量级的飞跃。同时其扫描精度也越来越高,100 m内测距精度优于2 mm。本文以天宝TX8三维激光扫描仪为例,介绍三维激光扫描测量的作业流程及三维激光扫描技术在炼化厂区改扩建中的作用。1某炼厂分馏装置区升级改造项目三维激光扫描测量
As a new mapping means, 3D laser scanning technology is more and more widely used due to its high speed, high precision and non-contact measurement. From 1000 points per second in the 1990s to more than 1 million points today, there have been several orders of magnitude leaps in scanning rates. At the same time, its scanning accuracy is also getting higher and higher, ranging accuracy of better than 2 mm within 100 m. In this paper, Tianbao TX8 three-dimensional laser scanner, for example, describes the three-dimensional laser scanning measurement process and three-dimensional laser scanning technology in the refinery plant expansion and expansion role.
