Application of Railway Engineering Survey Based on Remote Sensing Technology for Realistic Scenes

In order to promote the application of remote sensing technology in railway engineering surveys, the limitations of traditional remote sensing technology were analysed, and a novel remote sensing technology is proposed for realistic scenes. A complete remote sensing modelling method and production application process were established, based on the disparity function and double stereo orthoimages. Because the parallax and model baseline are in the same direction and the angle is eliminated, a dimensional model provides greater accuracy. Data from different professions transfer in both directions, based on a collaborative design platform. In various research and engineering practices, remote sensing technology for realistic scenes is widely applicable for different majors in railway engineering surveys, and it is effectual for unfavourable geological condition surveys as well as railway line selection. A work time saving of approximately 50% is achieved during the site survey period, and of approximately 20% during the interior design period. The proposed technology offers potential value for similar engineering applications and projects.
