Video Certification and Mobile Laser Scanning Data Based Automation of Electronic Maps Generation for Use with Locomotive Safety Devices and Traffic Control Systems

Abstract

The task of unified maps generation for various type locomotive safety and control devices proves to be an extremely crucial one. Its solution will lead to better traffic safety conditions and lesser electronic maps preparation costs. Railway infrastructure spatial data system (KSPD IZhT), containing coordinates of all the track objects in a high-precision coordinate system as obtained through processing of the mobile laser scanning outcomes, opens up new map generation opportunities. Information represents the total of track objects’ reflection points coordinated in three-dimentional space, evaluated within the sub-centimeter accuracy and annotated with photos, thus allowing to identify all the railway objects significant in the context of railway traffic safety provisions. The paper describes semi-automatic data origination process supporting electronic map montages generation procedure of operating domains. The presented automated generation procedures of unified electronic maps intended for various-type locomotive safety devices contribute to better productivity and unambiguity, elimination of subjective factor and consolidation of information updating process.
