| 摘 要： | 为了定量地评估激光测距仪的最大测程，并快速掌握激光测距仪在不同能见度下的具体性能，提出了一种最大测程数值算法，即通过结合激光测距方程和大气透过率计算公式来构建并求解超越方程的方法，可完成最大测程的定量计算。在此基础上，又提出了比例计算法来完成不同能见度下最大测程的等效推算。根据算法原理，分别进行了数值模拟计算，并给出了最大测程与能见度的关系曲线。数值模拟结果表明，该方法可以方便准确地完成多种情况下激光测距机最大测程的计算，具有定量直观、计算精度高、使用方便等优点，为激光测距仪最大测程的检测与评估提供了一种新方案。

| Abstract: | To evaluate the maximum range of laser rangefinder quantificationally, and to get the performance in different visibility rapidly, a new numerical algorithm was put forward. The empirical formula of atmospheric transmissivity was plugged into laser range equation, so a transcendental equation was generated and solved, the maximum range was calculated correspondingly. Based on the numerical algorithm, proportional method was applied to deduce maximum range in different visibility. The numerical simulative calculation of maximum range in different conditions was made by using this theory, and relation curves between maximum range and different visibility(Rmax-V) were drawn to explain the influence of visibility on maximum range visually. The simulation results show that the new numerical algorithm works well in calculating the maximum range of laser rangefinder. It has many virtues, such as quantitative results and high precision, etc. It provides a new approach to evaluate and assess the maximum range of laser rangefinder in lots of different situations. |
