Optical airborne camera (OAC) is a type of airborne instrument designed to collect image data as it passes over an earth-bound feature. OAC\'s use a number of different sensors including charge-coupled device (CCD) cameras and infrared (IR) cameras. OAC systems are used for a variety of applications, from terrain mapping and surveillance to detailed examination of urban and rural environments. OAC systems have become increasingly popular in recent years due to their ability to collect large amounts of data in a relatively short period of time.

OAC systems use two techniques to capture image data: image stitching and image blending, which involve overlapping multiple images to create a larger, more detailed image. Image stitching takes several individual images and combines them into one larger picture. The technique relies on the CCD cameras or IR cameras to capture multiple images that overlap each other. Software algorithms are then used to correct for spacing discrepancies and to stitch the images together. Image blending is similar to image stitching, but it uses software algorithms to blend the overlapping images together in order to create a much smoother and more natural looking image than image stitching alone.

The primary use of OAC systems is to create detailed digital maps. These detailed maps can be used to monitor terrain, assess land-use changes, track the progress of development projects, and detect and measure surface features. In addition, OAC systems can be used to monitor and document events such as floods, landslides, fires, and other natural disasters. OAC systems are also used to create digital elevation models, which are used to analyze topography and to design roadways, railways, and other types of infrastructure.

OAC systems are also used in the military for surveillance operations and battlefield monitoring. These systems can be used to track the location of troops, monitor battlefields, and conduct reconnaissance missions. In addition, OAC systems can provide valuable images of difficult-to-reach areas during military operations.

OAC systems are easy to deploy and operate. The OAC system requires the installation of a platform, such as an aircraft or a ground vehicle, to carry the OAC equipment. The instrument is then connected to a dedicated computer, which provides the control and data processing functionality. Once the system is installed, the OAC system is ready to collect data. The advantage of OAC systems is that they are fast to deploy, require minimal setup, and do not require complex calibrations.

OAC systems have become an essential part of modern mapping and surveying operations. With the help of OAC systems, professionals are able to quickly and accurately collect data for detailed maps and digital elevation models. OAC systems are cost-effective, easily deployable, and require minimal maintenance, making them an ideal solution for a wide range of applications.
