  • Patent number: 11856298
    Abstract: An image processing method according to the present invention includes the steps of acquiring a first frame image and a second frame image, determining, based on a difference between the first frame image at a first time and the second frame image at the first time, whether or not a deviation has occurred therebetween, calculating a correction value based on an amount of deviation when it has been determined that a deviation has occurred, correcting the first frame image and the second frame image at the first time based on the correction value, and synthesizing the corrected first frame image and the corrected second frame image.

  • Publication number: 20220262094
    Abstract: An image processing method includes: acquiring first and second frame images shot by cameras; acquiring first state information of an unmanned aerial vehicle and second and third state information of the cameras; extracting feature point groups from the first and second frame images; calculating correction values based on the state information at the first time and state information at a second time; outputting the extracted feature point groups as corrected feature point groups at the first at a predetermined timing, and correcting feature point groups at the second time as the corrected feature point groups at the first time at a timing other than the predetermined timing; calculating a transformation parameter using the corrected feature point groups; performing projective transformation of the first and second frame images based on the transformation parameter; and synthesizing the first and second frame images after the projective transformation.

  • Publication number: 20220222834
    Abstract: An image processing system (100) includes an imaging range specification unit (52), an overlapping region estimation unit (53), a transformation parameter calculation unit (54), and a frame image synthesis unit (55). The imaging range specification unit (52) specifies first imaging information based on first state information indicating a state of a first unmanned aerial vehicle (101) and second state information indicating a state of a first camera (107a), and specifies second imaging information based on third state information indicating a state of a second unmanned aerial vehicle (102) and fourth state information indicating a state of a second camera (107b). The overlapping region estimation unit (53) calculates a corrected first overlapping region and a corrected second overlapping region in a case where an error of a first overlapping region and a second overlapping region exceeds a threshold.
