Building and roof survey by drone

Building and roof surveys by drone Cost The cost of erecting scaffolding, ladders, lifts and undertaking work at height comes with increased risks and expense. Try an alternative option, our drone service. Our registered drone service may be applied to any building and is especially ideal for older tall buildings and areas of difficult access. All drone flights are carried out with minimum disruption to your daily routine. Why a drone is better Drones are flown into areas where there is little or no easy access and can zoom in close to view those delicate and sensitive areas. Areas such as glass roofs or decaying architectural work, where careful surveys are required are exactly where the drone excels. Accurate  Drone surveys are highly accurate and do not require the intense preliminary work that traditional surveys need to undertake; such as abseiling services, ladders, scaffolding, pickers & lifts. Weather issues also come into play, drones do not like gusts of wind, but they have no issues with many of the weather conditions that call-off manual inspections. Inspection Drones can quickly put your mind at ease, by inspecting dilapidated, hard to reach, delicate building areas or roof problems. Big or small, surveying manually can be a complex and costly affair. Use our drone service to carry out useful surveys of your buildings. Our team of drones or (UAVs) are piloted by registered experienced operators, who have carried out work for civil engineering companies, homeowners, and filmmakers. Capture Our drones fly up to a height of 120m and can cover miles of terrain, though typically we fly a lot closer and survey smaller areas. Our fleet of drones capture real time information in full-colour high-definition (HD) clarity. The camera footage may be viewed live or stored digitally for closer inspection. We can cover outputs for use in a wide range of other applications. Save time For reduced health & safety, environmentally friendly, highly manoeuvrable, quicker, and precise surveys call out the drones.

Photogrammetry for Archaeology

Photogrammetry for ArchaeologyDiscover the Power of Photogrammetry in ArchaeologyPhotogrammetry, creates highly accurate records of topology, objects, features, and landscapes. In the field of archaeology, the use of photogrammetric methods has witnessed a remarkable surge in recent years, enabling comprehensive documentation of everything from expansive landscapes to intricate artifact models.At Commendium, we have worked on numerous projects focused on capturing the essence and context of diverse archaeological sites around the world. Using drone photography, we employ oblique and top-down aerial shots to generate astonishingly realistic 3D models that vividly depict the surroundings.How photogrammetry worksPhotogrammetry relies on capturing a series of overlapping photographs of the subject or site from multiple angles. These photographs are then processed using specialised software that analyses the images, identifies common points, and calculates their relative positions and orientations to generate a 3D model.Understanding the Process:Equipment Requirements:To embark on a photogrammetry journey, you'll need the following essential equipment:Camera: A digital camera capable of capturing high-resolution images is recommended. DSLR or mirrorless cameras with interchangeable lenses are commonly used for their flexibility.Tripod: Sturdy tripods provide stability and ensure consistent framing across images.Targets: In some cases, using targets, 'distinctive markers or patterns placed strategically in the scene', can enhance accuracy and alignment during the processing stage.Optional: Drones equipped with cameras can capture aerial photographs, enabling detailed site documentation and topographic mapping.Important Considerations:To achieve the best results with photogrammetry in archaeology, keep the following in mind:Lighting: Optimal lighting conditions are crucial. Aim for even lighting without harsh shadows or blown-out highlights.Overlap: Ensure sufficient overlap between consecutive photographs (typically around 60-80%) to facilitate accurate reconstruction.Consistency: Maintain consistency in camera settings (e.g., focal length, aperture, ISO) throughout the capture process to ensure uniformity in image quality and scale.Scale: Incorporating a scale reference, such as a ruler or known object, in the photographs provides a reliable size reference for accurate measurements in the final model.Capturing Techniques:Consider the following techniques to capture photographs for photogrammetry:Site-Level Photogrammetry: Capture multiple images from different angles, ensuring coverage of all desired elements in the scene. Vary heights, perspectives, and distances to capture comprehensive data.Object-Level Photogrammetry: When focusing on individual artifacts, capture multiple images from various angles while maintaining a consistent distance and lighting setup. Incorporate close-ups to capture intricate details.Software and Processing:Choose suitable photogrammetry software based on your specific requirements. Popular options include Agisoft Metashape, RealityCapture, and Pix4Dmapper. These software packages facilitate the reconstruction of 3D models using the…
