You may be wondering what factors affect the result of aerial photography in Dubai. Those factors include atmospheric conditions, camera tilt, and cloudiness. These conditions can affect your results and influence the pictures’ quality. The good news is that there are several factors you can control, including the clouds and camera tilt. Read on for more information! But how do you ensure a quality shot? The following tips should help you achieve the desired aerial photo result.
Cloudiness:
Cloudiness is an important environmental factor when flying a drone. The presence of fog, clouds, and smoke all affect the performance of different cameras. These factors are treated as disadvantages in remote sensing. Poor weather conditions reduce image clarity, restrict search and rescue activities, and limit the effectiveness of aerial photography. However, data processing techniques can help mitigate the effects of deteriorating image clarity.
Camera tilt:
Camera tilt is one of aerial photography’s most significant sources of error. A photograph is not a true bird’s eye view if the camera is tilted. This will also result in perspective convergence, where the heights of the grid cells are converged to a point in the distance. Stabilizing the camera and flying the aircraft perpendicular to the ground is important to prevent this. Aerial photographs can be analyzed to see which planes have a slight tilt.
The amount of tilt is measured in degrees. Generally, a camera tilt will affect the angle between the photograph’s horizontal and vertical planes. The optical axis is parallel to the ground in a vertical photograph and points vertically upward. This is called the nadir point—the angle between the two forms the principal plane of the photograph. The camera’s horizon will not be visible in a horizontal photograph.
Atmospheric conditions:
It is well known that the atmospheric conditions of a given area influence the results of aerial photography. However, there are some methods to improve the quality of these images. In addition to air quality, atmospheric conditions affect the reflectance coefficient of the image. These methods include using an atmospheric correction model.
Aerial photography generally involves taking photographs under a clear sky with the sun relatively high in the sky. This provides good top lighting for the Earth’s surface, and uniformly indirect lightning is preferred in some circumstances. In addition, the camera’s position also affects the nature of reflected solar radiation.
