AI Article Synopsis
- Uncooled and shutterless microbolometer cameras are efficient for infrared imaging on small satellites and drones due to their lightweight and passive design.
- Radiometric compensation is crucial for ensuring the accuracy of the images, especially in applications requiring precise radiometric data.
- The study investigates how the camera's environment affects radiometric accuracy and proposes hardware and software solutions that maintain calibration validity for up to 3 years based on indoor experiments.
Article Abstract
Uncooled and shutterless microbolometer cameras are good candidates for infrared imaging systems installed on small satellites or small unmanned aerial vehicles: they are light and passive since no cooling system or mechanical shutter is required and they can be operated at ambient temperatures. However, the radiometric compensation has to be carefully performed to make the system compatible with applications where the radiometric accuracy of the images is mandatory. In this paper, we study the impact of the camera environment to the radiometric accuracy of the images. We propose and test hardware and software solutions to improve this accuracy and the quality of the radiometric images. We show that the radiometric calibration of the camera with our model is valid over a long time period- about 3 years-using in-door experiments.
