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)

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)

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)

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 (EO) 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 open source to business. Users can host and review code, manage projects and build software alongside 31 million developers. However, taking the Oxford English Dictionary's definition of AI as ‘systems able to perform tasks normally requiring human intelligence’, AI has been... (read more)

Parrot Unveils Imaging Drone ANAFI Thermal

Parrot, the leading European drone group, has launched ANAFI Thermal – a drone capable of capturing both live and recorded 4K HD video and thermal imaging of surfaces, structures and potentially dangerous areas for professional uses. The drone utilizes Parrot's ANAFI drone platform and equips it with a built-in 4K HDR camera with a 21-megapixel Sony sensor, as well as a FLIR radiometric thermal-imaging camera, complete with 160x120 resolution and a temperature range of 14°F to 752°F (-10°C to 400°C). ANAFI Thermal's gimbal can tilt vertically 90° upward or downward, giving professionals an unprecedented field of view. A 3x digital zoom allows pilots 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)

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)

Leica Airborne Imaging Capabilities Enhanced with Hyperspec Sensors

Leica Geosystems and Headwall Photonics announces the establishment of a partnership agreement whereby Leica will resell and integrate Headwall’s line of hyperspectral imaging sensors into their airborne product portfolio. Leica have selected Headwall’s hyperspectral imaging sensors to meet the growing demand for advanced hyperspectral sensors that acquire imagery data, which includes both spatial and spectral (chemical) information within the mapping area of interest. Hyperspectral imagery allows users to obtain critical information relative to the material composition of objects in the field of view of the sensor. The sensors generate a very high resolution hyperspectral datacube that allows users to map... (read more)
