摘要
为了提高基于激光测距仪测量地面工程坡度的精度,分析了其测量坡度时存在的问题,阐释了相关原理,结合在标准坡面上多次实测的结果,并考虑在实际测量中较难找准与坡面斜度一致的倾斜线等因素,提出了基于最小值平均的改进方法。经实际测量验证,该方法能满足地面工程坡度测量误差≤1°的要求。
To improve the precision of measuring ground-engineering-grade using laser range finder, this paper analyses the prob-lem of measuring grade using laser range finder and illustrates relevant principles. Based on results of multiple actual measurements on standard slope, and in consideration of the difficulty in finding the inclined line identical with the measuring slope practically, we puts forward an improved method based on the minimum mean. Actual measurement proves that the improved method could conform to the requirement of the ground-engineering-measuring-slope error ≤1°.
