While surveying with drones, images of the bottom are taken from multiple vantage points. Through processing these images, a photogrammetry software may then create orthomosaics and 3D models, from which it can measure accurate distance, and also surfaces and volumes of physical objects.
Data outputs from the drone
Images taken by the drone are usually saved on a memory card (such as Sdcard), just like for any other camera. Depending on the technology used by the drone, the images already are geo-tagged or can be imported in a geo-tagging software, such as WingtraHub. According to the size of the survey site, you probably have between a couple of hundred images and a few thousand, and each image contains geographical information (X, Y, Z).
Asbestos surveys Glasgow into a photogrammetry software
After importing or uploading the geo-tagged images in a photogrammetry software such as for example Propeller, Bentley ContextCapture or Pix4D, images will undoubtedly be stitched together to create 2D or 3D models of the surveyed site. Image processing could be a lengthy process based on the number of images and the performance of your computer. asbestos testing glasgow are desktop-based, thus requiring robust hardware. Other software is cloud-based, employing powerful servers instead of your local computer to process the info.
