摘要：Intensity images acquired with range imaging instruments can be used in the future for various applications, e.g. face recognition, assisting blind people in travelling and walking, automatic robotic vision, rendering 3D models and improving automatic recognition of objects. For the intensity information to be usable, it needs to be radiometrically calibrated. In this paper we propose the first empirical radiometric calibration method for range cameras to reduce errors caused by distance from the target and illumination falloff. With the proposed method we are able to correct images and facilitate their further use as well as make reflectance measurements. The use of range cameras in remote sensing is a new field of study, and no radiometric calibration methods for the intensity have thus far been proposed. We show that intensity calibration of the range camera is possible and applicable in remote sensing
