红外测距三角高程测量精度研究

On the Precision of Infrared Distance Triangulated Heliograh Survey

以实测数据为依据，按误差传播定律对红外测距三角高程测量的精度进行了分析，提出了在一定距离范围内红外测距三角高程测量能够代替三、四等水准测量。是林区等地形复杂，通视条件差的地区适用的高程测量方法。

Based on actually surveyed data, an analysis on the precision of infrared distance triangulated heliograph survery was done according to law of propagated error. It is thought that infrared distance triangulated heliograph could take the place of the third and fourth leveling survey, which had great significance in selecting heliograph survey method for the forest area with complex topography and poor through sight conditions.
