Abstract
Clouds are important in weather prediction, climate
studies and aviation safety. Important parameters include cloud
height, type and cover percentage. In this paper, the recent
improvements in the development of a low-cost cloud height
measurement setup are described. It is based on stereo vision
with consumer digital cameras. The cameras positioning is
calibrated using the position of stars in the night sky. An
experimental uncertainty analysis of the calibration parameters
is performed. Cloud height measurement results are presented
and compared with LIDAR measurements.
