Abstract
Official abstract text for this publication.
A cloud measuring system includes: a stereo camera capturing stereo images by cameras each changing pan and tilt angles; a camera control section controlling the pan and tilt angles to control imaging; a reception section receiving the stereo images; a matching coordinate acquisition section acquiring a feature point of an object in the stereo images, and acquiring, as matching coordinates, a combination of reference coordinates where the feature point is to be located in the images, and coordinates of the acquired feature point; a difference detection section acquiring a displacement amount of the feature point from the matching coordinates, acquiring direction difference amounts in pan and tilt directions from the displacement amount, and generating correction information; a correction processing section correcting the stereo images on the basis of the correction information; and a height estimation section estimating a cloud height on the basis of the corrected stereo images.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cloud measuring system comprising: a stereo camera that includes a plurality of cameras each capable of changing an angle in a pan direction and an angle in a tilt direction, and captures stereo images that include a plurality of images having disparity between each other; a camera control section that controls the angle in the pan direction and the angle in the tilt direction for each of the plurality of cameras to control capture of the stereo image…
