Absorption-Based Ranging from Ambient Thermal Radiation without Known Emissivities

Unay Dorken Gallastegi, Hoover Rueda-Chacon, Martin J. Stevens, and Vivek K Goyal

Not Accessible

Your library or personal account may give you access

Abstract

We present passive absorption-based ranging using long-wave infrared hyperspectral measurements of an outdoor scene. Regularization and parametric modeling of transmittance enable good accuracy without knowing temperatures or emissivities of scene objects, as validated with lidar.
