在运营线上进行测量不仅工作效率低而且不够安全。因此,人们都期待着航测方法能用于既有线路的测绘。要实现这一愿望,就必须解决如何在航摄像片上测定线间距、曲线要素和岔心坐标。而其中最关键的问题,是保证岔心坐标的精度。为了对这一问题进行探讨,去年我队结合××线生产任务,组织了“岔心试测小组”,在未作标志的航摄像片上进行了解析加密岔心坐标的试验。 Measuring on the operational side is not only inefficient but not secure enough. Therefore, people are looking forward to the aerial survey method can be used for mapping of existing lines. To achieve this desire, we must resolve how to determine line spacing, curve elements and bifurcation coordinates on aerial photographs. One of the most crucial issues is to ensure the accuracy of the fork center coordinates. In order to discuss this issue, last year my team combined with the production line of the XX line, organized the “fork test team” and did the test on the unlicensed aerial camera to analyze the encrypted fork center coordinates.
