Description

technical field [0001] The invention belongs to the technical field of informationization of railway and urban rail transit construction, and in particular relates to a 3DGIS-based railway field investigation system and method. Background technique [0002] The traditional railway field investigation method is to use photos and auxiliary materials to conduct on-the-spot interpretation in the field, find out and identify the nature, location and range of the ground objects by comparing the photos, and draw them on the photos according to the schematic symbols after comprehensive selection. The location, shape, attributes and other information of the ground objects are recorded in the field record book, and after the field investigation is completed, the investigation results will be digitally processed and processed by the in-house processing personnel. This traditional operation mode has low survey efficiency, many processes, long cycle and high cost, which has become a "bot...

AI Technical Summary

Problems solved by technology

This traditional operation mode has low survey efficiency, many processes, long cycle time and high cost, which has become a "bottleneck" to improve the efficiency of railway survey and design. Therefore, it is urgent to change the traditional survey operation mode
