Fotogrammetriaszenzorok refer to the sensors used in photogrammetry, a science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena. These sensors capture images from multiple viewpoints, which are then used to create three-dimensional models, maps, and measurements of the subject.

The most common type of sensor used in photogrammetry is a digital camera. These can range from standard consumer-grade cameras to highly specialized metric cameras designed for high accuracy. Drones equipped with photogrammetry sensors, often referred to as UAVs (Unmanned Aerial Vehicles), have become increasingly popular for surveying and mapping due to their versatility and accessibility. Aerial cameras mounted on aircraft are also widely used for larger-scale mapping projects.

In addition to visible light cameras, other types of sensors can be integrated into photogrammetric workflows. LiDAR (Light Detection and Ranging) sensors, for instance, actively measure distances by illuminating targets with laser light and measuring the reflected light's pulse. While LiDAR collects point cloud data directly, it is often used in conjunction with imagery from photogrammetry sensors to enhance detail and colorization of the resulting 3D models. Thermal sensors can also be employed to capture infrared radiation, useful for applications like inspecting infrastructure for heat loss or monitoring environmental changes. The choice of sensor depends heavily on the desired accuracy, scale of the project, and the specific application.
