High accuracy train borne surveying of the railway using multiple sensors

Bryce Lane, Commercial Director, Omnicom Balfour Beatty

Dr Jonathan Owen, Expert Engineer, Omnicom Balfour Beatty

Traditional surveying techniques on the railway are costly and dangerous. To perform surveys safely, lines must be closed or the survey must take place during other works. Vehicle-borne surveying systems mitigate these risks and constraints by operating at line-speed on rail vehicles. This allows infrastructure owners to manage their assets and perform measurements without the need for personnel lineside.

Omnicom Balfour Beatty have developed such a survey system, OmniCapture3D, consisting of two high resolution lasers, a calibrated HD camera and a highly accurate inertial positioning system cable of delivering sub-centimetre absolute accuracy. We have sought improvements in the video timing system so that OmniCapture3D video data could be used for performing accurate measurements.

The solution leverages Precision Time Protocol, a time synchronisation mechanism capable of under 1µs accuracy. The use of PTP allowed us to achieve excellent synchronisation with few physical design changes, as well as allowing for multiple cameras if required. The resulting system achieved a synchronisation accuracy of 7µs, a movement of under 0.3mm at 90 mph.

Bryce has nearly 20 years experience in the rail industry including roles in finance, construction, safety and systems engineering and information management. He has worked on numerous asset implementation, surveying and inspection projects from both client and supplier side and has worked for Omnicom Balfour Beatty since 2012 in a Business Develop and Account Management role.

Dr Jonathan Owen began working for Omnicom Engineering in 2001 after completing his PHD in Applied Mathematics. He has been instrumental in developing Omnicom’s world class surveying and positioning systems. As part of a team he has developed a set of geospatial mapping tools sitting above an Oracle database which allow network infrastructure owners to view and manipulate their linear and fixed asset data as well as manage services provisioned over these assets.

Direct Geopositioning with Low Cost Drones

Lewis Graham, President/CTO, GeoCue Group Inc

Mapping by drone is a cost effective solution for collecting geospatial data, from simple orthophotos to complex differential volumes. With the exception of simple visualisations such as video, all mapping products need accuracy. This presentation will define accuracy and review the requirement of various products. The range of options in to achieve such accuracies will be presented and the importance of camera calibration will be discussed. Direct geopositioning using low cost drones reduces and sometimes eliminates the need for ground control points. A series of real world mapping projects will demonstrate how direct geopositioning can be used to reduce on-site time and overall project cost.

Addressing the supply chain: the true ROI of UAV survey services

William Tompkinson, Principal, Insightful Dimensions

Reasons for utilising UAV surveys are discussed in terms of speed, accuracy and sensor choice. However, this can be a very short-term and insular view to whether UAV surveys are bringing benefit to customers. There is typically little discussion of the implications on supply chains. Drawing upon experiences of Canadian UAV survey company, Sumac Geomatics, in undertaking monthly volumetric monitoring contracts, this presentation will expand the scope of how we assess the impact of these activities. It will illustrate how when monitoring stockpiles, there can be technical decisions made by the UAV provider that will directly influence supply logistics and just-in-time strategies.

Using UAVs and photogrammetry for surveying road and railway embankment and cutting (earthmoving)

Siim Solovjov, Engineer, EIK Infrakonsult OÜ

Digital surface modelling using small unmanned aircraft systems (UAS) and photogrammetry have made huge advances in recent years. This great advancement in technology has created a serious alternative to traditional surveying methods like GNSS based measurements, tacheometry or laser scanning. For areas ranging from 1000 m2 to 10 ha and up where accuracy requirements are between 2-10 cm in elevation, it is an ideal tool to complement traditional surveying techniques.

Applications for digital surface modelling from photogrammetry are wide and it has found its way to fields from agriculture to virtual reality environment design. This seminar paper is focused on solutions and practices for using these advancements in surveying road and railway embankment and cutting (earthmoving). It also addresses how various aspects of technical choices affect the outcomes of using UAVs as surveying devices.

This seminar paper examines different technical, business and regulatory obstacles that need to be overcome to take full advantage of this new technology and make it one useful part in a box of tools in evaluating earthmoving volumes more efficiently. Experience is drawn from using different flight and camera platforms, workflows and software solutions in different road and railway construction projects, including failures and successes over last couple of years.

Case Study 1: Analysis of crowdsourced data from a distributed network of cyclists in Manchester

Philip McAleese, CEO, See.Sense

Like many major cities around the world, Manchester (UK) has had to contend with increased levels of urbanisation and population growth as people move to the city. With this trend expected to continue, the city’s transport infrastructure is facing increased strain as a rapidly expanding population navigate their way through the urban environment. It has therefore become a top priority to understand patterns of mobility to improve the transport network and maximise living standards. See.Sense, in collaboration with researchers from Queen’s University Belfast, is working with CityVerve, to build a more connected and mobile city through the use of sensor technology to identify its rapidly changing transport needs.

Case study 2: Does a smart city have to choose between standardisation and innovation?

Richard Woodling, Managing Consultant, Smart Practice, Ordnance Survey

What makes a city smart? A consistent theme is that it involves considering a city as a whole, rather than as a number of separate systems. For instance, making choices about transport, green spaces, air quality and health in a joined-up way can help make a city a more attractive and liveable place to live and work. However, cities are diverse. There is no one-size-fits-all formula which a city can adopt to make it smart.

GeoMOVE: Merge regional geological parameters with measured ground motion for the transport sector

Clare Roberts, Remote Sensing Consultant, CGG - NPA Satellite Mapping

Ground instability is present in many areas of the UK and can be due to natural geological processes such as shrink-swell clay or activities such as groundwater pumping and old mine workings. Conventional surveying techniques are capable of measuring surface movement and on-site monitoring networks can be installed in regions influenced by ground motion. However, it is not practical or cost-effective to install a large regional scale in-situ measurement network. Satellite imagery makes this possible and combined with geological information has led to the development of a unique source of regional ground stability data (1:50,000) called GeoMOVEâ„¢ (Geological Motion Observations & Velocity Evaluation), a targeting tool that identifies.
