Road inspection

Collection of high resolution data for road monitoring,certification, and traffic management projects using unmanned aerial vehicles and mobile mapping.

Scenario 1

Production of a map of roads and the surrounding area with the survey-grade accuracy using drones.

A high-precision base orthomosaic is formed for further infrastructure mapping, developing of a geodatabase and road network parameters acquisition.

sample orthomosaic

Performance

up to a 100 km of roads per day with a single UAV

Data product

orthomosaic with all road infrastructure elements captured in high-detail

Accuracy

of spatial positioning of any object down to 10 cm

Scenario 2

Production of a high-resolution map of roads using ground-based mobile LiDAR scanning

Performance

up to 60-80 km of road per day with one car

Data product

dense LiDAR point cloud, covering everything within 150 m around the scanner

Accuracy

positioning of any object with down to 5-7 cm accuracy

Data in 3D

take the advantage of the 3D data representation

Automation

automatically extract positions of target objects like road signs, light poles, etc.

Vegetation is not a hindrance

the scanner can pick up the objects even they are obscured by the vegetation

Orthomosaic

to make the subsequent vectorization more convenient, we create a point cloud based orthomosaic of the road and adjacent territory

Mobile scanning system AGM-MS2.200

  • Inertial system AGM PS M30
  • Velodyne VLP 32 scanning system: Scanning frequency
    600kHz, Maximum range 200 m, field of view 360°
    degrees, scanning mirror rotation speed 20 rps
  • 2-frequency multi-system GNSS 20 Hz

Point cloud density

  • 5000 points per square meter on the road surface at a speed of 20 km/h
  • 500 points per square meter on the road surface at a speed of 70 km/h

Application

  • road scanning for inventory and certification
  • scanning for topographic plan production
  • mapping the areas where UAV flights are forbidden or impossible

Deliverables

Road and traffic organization scheme

 based on the results of UAV surveying and/or ground based mobile LiDAR scanning

Technical passport

of a road designed based on the results of UAV surveying and/or ground based mobile LiDAR scanning
