摘　　要：由于目前依据点云自动成图技术瓶颈仍未打通,传统高精度无人驾驶地图仍然采用人机交互方式绘制。为解决绘制高精度地图任务难度系数定级问题,通过将测量平差理论知识与方差相结合建立数据模型,根据计算效率均值的误差改正数,并利用改正后效率均值对比前后均值误差值离散程度,取绘制效率倒数确立单项绘制地图要素难度因子,合理量化绘图任务难度系数,并成功研发根据任务难度系数分配作业任务的系统。本文导出公式及结论可较好解决当前地图任务难度难以界定与合理分配制图任务机制的问题,为高精度地图制图公司及相关计件工资工作提供了借鉴方法。At present,the bottleneck of automatic mapping technology based on point cloud has not been opened yet,the traditional high⁃precision unmanned map is still drawn by human⁃computer interaction.In order to solve the problem of grading the difficulty coefficient of drawing high⁃precision map.In this paper,the data model is established by combining the theoretical knowledge of measurement adjustment with variance.According to the error correction number of calculating the efficiency mean,and using the corrected efficiency mean to compare the dispersion degree of the mean error value before and after correction,the reciprocal of drawing efficiency is taken to establish the difficulty factor of single map element,and reasonably quantify the difficulty coefficient of drawing task,then successfully develop a system to assign tasks according to the task difficulty coefficient.The formulas and conclusions derived in this paper can better solve the problem that it is difficult to define and reasonably allocate the mapping task mechanism,and provide a reference method for high⁃precision mapping companies and related piece work.
