What Is Aerial Photography
Aerial photography is the taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically. Platforms for aerial photography include:
multirotor Unmanned Aircraft Systems (UAS).
Uses for Aerial Photography:
Aerial photography is used in cartography (particularly in photogrammetric surveys, which are often the basis fortopographic maps), land-use planning, archaeology, movie production, environmental studies, surveillance, commercial advertising, conveyancing and artistic projects. In the United States, aerial photographs are used in many Phase I Environmental Site Assessments for property analysis.
With advancements in video technology,aerial videois becoming more popular.Orthogonal video is shot from aircraft mapping pipelines, crop fields, and other points of interest. Using GPS, video may be embedded with meta data and later synced with a video mapping program.
This “Spatial Multimedia” is the timely union of digital media including still photography, motion video, stereo, panoramic imagery sets, immersive media constructs, audio, and other data with location and date-time information from the GPS and other location designs. Aerial videos are emerging Spatial Multimedia which can be used for scene understanding and object tracking. The input video is captured by low flying aerial platforms and typically consists of strong parallax from non-ground-plane structures. The integration of digital video, global positioning systems (GPS) and automated image processing will improve the accuracy and cost-effectiveness of data collection and reduction.
Making use of remotely piloted aerial platforms in the automotive industry, whether at a race track or in a parking lot, creates a whole new perspective and adds a dramatic view point which cannot be achieved from the ground. They are also safer, as they reduce the risk of having a camera man trackside and in harm?s way. Even though the aerial component may only last a few moments, it adds a professional touch to any motoring video.
The use of UAV’s or drones for architects is relatively new to the industry. Architects have found that making use of a remotely piloted aerial platform is far easier, quicker and more cost effective that using a full size aircraft. 3D computer generated images can be layered over aerial photographs as well as video to create a realistic rendition of the architect’s vision.
Industrial Aerial Photography
Industrial sites can be quite hazardous places and using a UAV to take aerial photos or video of a construction site, for instance, not only shows a whole new perspective, but is also a whole lot safer. In some cases, using a UAV also negates a site from being shut down for safety reasons for surveying or inspection, as there is no risk to personnel on the ground. Inspection of power lines or high structures can also be performed remotely, thus reducing the risk of injury or even death.
Today?s Real Estate market is very competitive and in order to stay ahead of the rest, it is crucial for any reputable estate agent to have the best possible images of any house. Adding aerial photos to your listing, is a huge leap forward and creates a whole new perspective and dimension. The surrounding area is now visible and things like elevation, vegetation and stand size is much better illustrated.
