摘要
无验潮测量模式下虽然解决了验潮站设立等人工因素带来的误差,但未顾及测深仪信号延迟、气象因素、湖泊或海域等地理特定因素所带来的测深误差。为了有效提高水下地形测量作业的精度,依托无验潮测量模式的优势,结合当前测量设备并综合分析各类误差产生的机理,确定相关误差改正模型,并根据模拟数据对测深误差进行定性、定量的分析。结果表明:针对水深测量作业误差产生的因素,根据误差产生的机理,从误差源上分析误差改正的方法,能够有效地提高水下测量作业的精度。
For no tide sounding model solved errors caused by artificial factors from side station,but no misgiving the errors caused by signal delay of sounding meter,meteorological factor,lake or sea and other geography specific factors.In order to increase precise of underwater topographic survey,with the advantage of no tide sounding model,the current measuring equipment and all mechanisms of errors,some related error correcting model was determined,also,according to the simulated data,the sounding error was qualitatively and quantitatively analyzed.The results show that aiming at factors causing errors in sounding survey,by mechanism causing errors,analyze correcting errors methods from error source,so underwater measurement precise can be improved efficiently.
