Aerial cameras are specialized instruments used in surveying and mapping to capture high-resolution images from an elevated perspective. They are essential tools for a variety of applications, including: urban planning, environmental monitoring, infrastructure inspection, and land surveying.
Here are some characteristics of aerial cameras:
• Size: Aerial cameras are large and automatic, and are mounted on aircraft.
• Accuracy: Aerial cameras are built with high geometric and radiometric accuracy.
• Image quality: Aerial cameras are designed to expose a large number of high- quality photographs in quick succession.
• Lens: Aerial cameras have good quality lenses.
Types: There are many types of aerial cameras, including aerial mapping cameras, reconnaissance cameras, strip cameras, panoramic cameras, multi-lens cameras, and digital cameras.
• Mounting: Aerial cameras can be mounted on a variety of platforms, including drones, helicopters, mobile mappers, and fixed-wing aircraft.
• Image capture: Some aerial cameras capture images vertically downward (nadir), while others capture images at an angle (oblique) to the ground.
• Passive Sensors: Aerial cameras are considered "passive sensors" because they detect and capture the natural light reflected from objects.
