【摘要】：市政管線建設(shè)中,相應(yīng)的地形圖對其規(guī)劃、設(shè)計等起著至關(guān)重要的作用。傳統(tǒng)方式在市政管線地形圖測量中有一定的局限性,特別是大城市的重要交通要道、快速路等。而車載移動測量系統(tǒng)則有其得天獨厚的優(yōu)勢,快速、高效、安全。在測圖過程中,車載移動測量系統(tǒng)精度受各方面的影響,如車速、地面遮擋、控制點布設(shè)等。本文對車速、控制點布設(shè)線路等方面進行了試驗驗證,結(jié)果表明,通過一定的質(zhì)量控制措施,車載移動測量系統(tǒng)能夠很好地應(yīng)用于市政管線地形圖測量中。
[Abstract]:In the municipal pipeline construction, the corresponding topographic map plays an important role in its planning and design. The traditional method has some limitations in surveying the topographic map of municipal pipelines, especially the important traffic routes and expressways in big cities. The vehicle-mounted mobile measurement system has its unique advantages, fast, efficient and safe. In the mapping process, the accuracy of the vehicle moving measurement system is affected by various aspects, such as speed, ground occlusion, control point layout and so on. In this paper, the vehicle speed and the layout of the control points are tested and verified. The results show that the vehicle-mounted mobile measurement system can be applied to the topographic survey of municipal pipelines well through certain quality control measures.
