实测结果表明,在林区进行地形、公路和其他工程测量,采用红外测距仪间接高程代替水准仪直接高程,完全达到四等水准测量的精度,且减少了水准仪高程控制测量的工序,可大大提高了测量工作效率。文中详细介绍了测量方法和实例。 The measured results show that in terrain, highway and other engineering surveys, the indirect elevation of infrared rangefinder replaces the direct elevation of level, which fully achieves the accuracy of the fourth-level leveling measurement and reduces the process of elevation control measurement, which can be greatly improved The measurement of work efficiency. The paper introduces the measurement methods and examples in detail.
