Title:
IMAGE PROCESSING METHOD, IMAGE PROCESSING DEVICE AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/235063
Kind Code:
A1
Abstract:
An image processing method according to the invention comprises the steps of: acquiring first and second frame images captured by cameras 3a, 3b at a first time; acquiring first state information of a pilotless aircraft as well as second and third state information of the cameras 3a, 3b at the first time; extracting groups of feature points from the first and second frame images; calculating correction values on the basis of the state information at the first and second times; at a predetermined timing, outputting the extracted groups of feature points as the corrected groups of feature points at the first time, whereas, at timings other than the predetermined timing, correcting the groups of feature points at the second time by use of the correction values and then outputting the resultant groups of feature points as the corrected groups of feature points at the first time; calculating transformation parameters by use of the corrected groups of feature points; performing projective transformation of the first and second frame images on the basis of the transformation parameters; and combining the first and second frame images as projective-transformed.
