Description: Aerial images are visual captures obtained from an elevated perspective, typically using aircraft, drones, or satellites. This process allows for a panoramic view of the Earth’s surface, resulting in a visual representation that can be used for various purposes. Aerial images are fundamental in the field of computer vision, as they provide visual data that can be analyzed and processed to extract relevant information. These images can vary in resolution and quality, depending on the altitude from which they are captured and the equipment used. Additionally, the interpretation of these images can reveal patterns, structures, and geographical features that are not easily visible from ground level. The ability to analyze aerial images using computer vision algorithms has revolutionized the way tasks such as mapping, urban planning, and natural resource management are conducted. In summary, aerial images are a powerful tool that combines technology and visual analysis to offer a deeper understanding of the terrestrial environment.
History: The use of aerial images began in the late 19th century when the first photographs were taken from hot air balloons. However, it was during World War I that this technique was perfected for military purposes, allowing for the acquisition of strategic information. With technological advancements, in the 1930s, airplanes equipped with cameras were introduced for topographic mapping. Starting in the 1960s, the use of satellites became popular, enabling the acquisition of large-scale and high-resolution aerial images. In recent decades, the development of drones has revolutionized aerial image capture, making it more accessible and versatile.
Uses: Aerial images are used in a variety of fields, including agriculture, urban planning, natural resource management, environmental monitoring, and disaster response. In agriculture, they allow for monitoring crops and assessing plant health. In urban planning, they help visualize infrastructure development and land use. In natural resource management, they are used to map forests, water bodies, and protected areas. Additionally, they are essential in disaster response, as they provide quick information about affected areas.
Examples: An example of the use of aerial images is crop monitoring using drones, which allows farmers to identify areas that need attention. Another example is the use of satellite images for water resource management, where water bodies can be mapped and their quality assessed. Additionally, aerial images are used by authorities for city planning, helping to identify areas for expansion and development.
