Imaging the Banqueting House Ceiling

John Hallett-Jones, Director of Glanville Geomatics, describes a new technique for high-resolution imaging of historical objects like ceiling paintings and mouldings where sub-millimetre pixel resolution is called for. Over recent years, heritage recording has undergone massive change. Improvements in terrestrial scanning, digital imaging and the ability to navigate these datasets using mobile devices has provided the surveyor with a wealth of new opportunities to deliver quantitative and qualitative information at a resolution never before commercially achievable. In order to provide a cost-effective approach to digital recording to the historic sector, we highlight a technique developed to swiftly capture high-resolution seamless... (read more)

Surveyors Opt for 360 Degree Colour Imaging

Capturing the finer details and colours of a Norman castle for an orthophoto can be challenging. One survey company found the Spheron HDR camera was just right. There is an increasing demand for survey companies to use technology which effectively captures reality, right down to tiny details. One device which can help is the Spheron SceneCam, a unique mobile reality capture device – an automatic camera technology which is able to provide full spherical imagery of sites or locations. The camera captures high quality full spherical HDR 360° × 180° uninterrupted views and is also able to provide 3D measurements.... (read more)

MDA Expands Imaging Modes for RADARSAT-2

Richmond, BC –MDA’s Information Systems group has commercially launched a new imaging mode for RADARSAT-2. The new Extra-Fine mode provides an unprecedented ability to capture exceptional resolution imagery over large areas, providing a capability that is ideally suited to support monitoring large areas coupled with identifying detailed changes. The Extra-Fine imaging mode is able to provide single polarization synthetic aperture radar (SAR) imagery at a 5 metre resolution, over a 125km x 125km area (or 15,625 km2 per scene). The RADARSAT-2 satellite has global high-resolution surveillance capabilities that include a large collection capacity and high accuracy. The satellite acquires data... (read more)

Technology Convergence - Artificial Intelligence and Satellite Imaging

Artificial Intelligence (AI) has been used for years on satellite images – so why all the excitement? The application of AI and Machine Learning (ML) to Earth Observation data is a huge growth area, demonstrated by the many online competitions, GitHub repositories and entire businesses founded exclusively on this topic. GitHub is a development platform inspired by the way people work, from opensource to business. Users can host and review code, manage projects, and build software alongside 31 million developers. However, taking the OED definition of AI as ‘systems able to perform tasks normally requiring human intelligence’, AI has been available for many years... (read more)

SphereVision 360 Imaging Software Integrates iSTAR Measurement Module

Arithmetica has released a new version of the SphereVision 360 degree imaging software with support for NCTech’s industrial grade iSTAR panoramic camera. SphereVision Project Builder now includes functionality allowing iSTAR users to capture measurements directly from within a spherical image. With applications including forensic evidence collection, as built surveying, asset management and construction, for example, this functionality is designed for iSTAR users who want fast data capture within their existing workflow. The ability to capture measurements from iSTAR 360-degree imaging is in addition to the existing functionality of SphereVision Project Builder. The 360-degree imaging software already allows for the integration... (read more)

Aerial Imaging Market Valued at US$4bn by 2024

A new report by Global Market Insights has projected the market for aerial imaging services to be worth US$4 billion by 2024, with UAVs primarily driving the anticipated growth. The report characterises the uptake of UAVs for aerial photographic capture as ‘exponential’ over the past decade, with the majority of use over this period driven by the real estate sector in urban areas. Photography of construction sites in these environments is served by these platforms far more effectively than traditional flight platforms due to key cost and maneuverability benefits. Startlingly, the report also notes the sharp increase in the incidence... (read more)

Hyperspectral Imaging for Agriculture Ready for Take Off

A German company has developed a lightweight hyperspectral sensor suitable for mounting on a UAV with applications in agriculture, reports Richard Groom. Hyperspectral and multispectral imaging is usually associated with satellite or aircraft imaging platforms, but German company Cubert has developed a sensor that, at 470g, is so light that it can be carried by a UAV. The combined system uses an Octocopter platform and is called Firefly. Cubert’s UD-185 sensor uses full-frame imaging technology, which captures each frame in a millisecond and avoids the complications introduced when using scanning technologies for digital imagery. The data can be transferred to... (read more)

UC Santa Barbara Develop 3D X-Ray Imaging

Using off-the-shelf drones, WiFi transceivers, and Tango-enabled tablets, researchers at UC Santa Barbara have developed a way to perform 3D imaging of objects hidden by walls. The technique is conceptually simple: Two drones work together, flying around a brick house with a hidden interior. One drone broadcasts a WiFi signal, and the other drone captures the signal from the other side of the house. The solution builds on earlier work in sensing and imaging using WiFi. Back in 2010, the lab demonstrated 2D imaging using WiFi signals and terrestrial robots. “However, enabling 3D through-wall imaging of real areas is considerably... (read more)
