Positional Video Survey
• The next stage in the development of
the video capture was to produce a
Positional Video Survey
• A GNSS-aided Inertial Measurement
Unit provides geo-location and
orientation measurements of the
captured video frames
• Low profile HD video camera and IMU
mounted to give a driver’s eye view of
the railway
Geo-Referenced Video Frames

Positional Video Survey
• Video Calibration Tool providing
visual context to CAD data
• Geo-referenced Video Frames
are synchronised to model data
in Bentley Microstation 3D CAD
software
• The video trace is transformed to
different survey grids such as
SnakeGrid, to match existing
survey information
Geo-Referenced Video Frames
7

Mobile Laser Survey
• In areas where there is limited
existing or current survey the
addition of a TOPCON mobile
mapping system allowed us to
produce laser scans along with the
video survey
• High density coloured point cloud
produced at 700kk points per
second
• Collected using timetabled in service
locomotives minimising the
requirement for surveyors on the
ground
Data Collection
