🚀 Railways Embrace Drone Technology for Enhanced Surveys 🚀

 Introduction: The drone industry is soaring, with projections reaching billions in the coming decade. As sectors worldwide tap into its potential, the railway industry is leading the charge in leveraging drones to overcome traditional inspection challenges. Manual track inspections are not only time-consuming but also pose significant safety risks. Enter drones: capable of delivering high-resolution 2D models of extensive railway sections, depots, and stations with unprecedented efficiency.

Methodology: Drones, or UAVs (Unmanned Aerial Vehicles), offer a game-changing approach to railway inspections. These versatile aircraft, controllable remotely or autonomously, can gather critical data swiftly and safely. By minimizing human presence on active tracks, drones reduce accident risks and expedite the inspection process.

Benefits of Using Drones in Railways:

  1. Save Time: Drones streamline data collection across multiple tracks, automating the process to create a portable, repeatable, and efficient method.

  2. Safety: By keeping personnel off active tracks, drones mitigate the inherent risks of railway inspections, making the process safer for everyone involved.

  3. High-Resolution Data: Drones capture detailed, high-resolution imagery, facilitating comprehensive analysis. This includes:

    • Orthomosaic (2D Map)
    • Digital Terrain Model
    • Digital Surface Model
    • Point Cloud
    • Aerial Video

Use Cases:

1. Bhandarkund-Bhimalgondi Railways Stations Survey (BDKD-BMC):

  • Introduction: South East Central Railway engaged Aerizone for a 21 km aerial survey amidst challenging terrain.
  • Data Acquisition: Ground Control Points (GCPs) were established for precision, followed by data collection over two days.
  • Data Processing: The analytical team processed the data within two days, yielding high-resolution orthomosaics, feature extraction, and aerial video surveys.
  • Deliverables: High-Resolution Orthomosaic, Feature Extraction, Aerial Video Survey.

2. Sonegaon-Chitoda Railway Stations Survey (SNN-CHJC):

  • Introduction: Central Railway appointed Aerizone for an aerial video survey to enhance inspection efficiency and safety.
  • Data Acquisition: With minimal flights required, data collection covered the 13 km track swiftly.
  • Data Processing: The raw video data was classified and analyzed for detailed insights, including location and feature markers.
  • Deliverables: High-Quality Aerial Survey Video, Feature Extraction, Orthomosaic, Digital Surface Model, Digital Terrain Model, Contour Map.

Deliverable:
