| 摘 要： | 激光船模轨迹仪是自航船模航迹和二维姿态的激光自动测量系统。它是采用激光扫描测角和三角方法求出船模轨迹和姿态数据。由于测角系统的随机误差使所测船模上固定点的位置产生了偏差。本文着重分析一定概率下测角误差和船模位置偏差之间的关系,给出误差公式和一定区域上误差分析等精度曲线,最后讨论最佳工作区域问题。所得结果为激光船模轨迹仪的正确使用提供了依据。

| Abstract: | The laser ship-model track-meter is an automatic measuring system basedon the principles of laser.It is used to measure the track and two-dimensionalattitude of a ship model.The methods of laser scanning angular survey andtriangulation are adopted to collect the data of track and attitude.Because ofrandom errors of the angle-measuring system,deviation of the model position isliable to occur.This paper emphasizes the analysis of the relationship betweenthe error of angular survey and the deviation of the model position under someprobability,and gives the error formula and error distribution(the curve ofisoprecision)in some areas.Finally,the optimum operational area is discussed.The results provide a basis for the correct use of this apparatus. |
