What is a sensor model? And its classification? What is the calculation scheme of rational function model?

Sensor is a kind of detection device that can sense the measured information, and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of sensors include miniaturization, digitalization, intelligence, multi-function, systematization and networking, which are the primary links to realize automatic detection and control.

Rational function model is a more general and perfect expression of geometric models of various sensors, which is suitable for various sensors. Many satellite image providers consider using this model as the transmission standard of image data.

Rational function model can achieve the accuracy of strict imaging model and has the ability to complete photogrammetry processing instead of strict imaging model. At the same time, the rational function coefficient without physical meaning can effectively hide the imaging parameters of the sensor.
