  • Patent number: 9532035
    Abstract: An imaging system on an aerial vehicle, includes: a group of rotating camera including at least a first and a second rotating cameras on the aerial vehicle; and a control part which controls a first virtual rotation track of the first rotating camera and a second virtual rotation track of the second rotating camera and allows shots to be taken at multiple photograph-shooting points on the first virtual rotation track and the second virtual rotation track; wherein the control part controls a set of multiple photograph-shooting points on the first virtual rotation track and those on the second virtual rotation track to be substantially in a grid shape. Accordingly, a 3D image could be acquired by using the group of rotating cameras on the aerial vehicle during a relatively short endurance flight and more information on images created in such a method could be estimated.

  • Patent number: 9513404
    Abstract: An apparatus for meteorological observation is provided. The apparatus includes: a body part; a coupling part which moves along a first and a second guiding routes alternatively by a motor; a sensor part which rotates according to a movement of the coupling part; and a shoot controlling part for measuring data of the upper atmosphere when the coupling part is placed on the top guiding member while moving along the first guiding route, (ii) measuring data of front lower atmosphere when the coupling part is placed on the first branch while moving along the first guiding route, (iii) measuring data of the upper atmosphere when the coupling part is placed on the top guiding member while moving along the second guiding route, and (iv) measuring data of rear lower atmosphere when the coupling part is placed on the second branch while moving along the second guiding route.

  • Patent number: 9367919
    Abstract: A method for estimating a position of a target by using an image acquired from a camera is provided. The method includes the steps of: (a) setting multiple virtual estimated reference points by dividing a view-path; (b) comparing altitude values of the respective estimated reference points with those of respective points on terrain; (c) searching neighboring virtual estimated reference points among the multiple virtual estimated reference points to satisfy a requirement under which a difference between an altitude zk of one point among the neighboring estimated reference points and that of the terrain corresponding thereto and a difference between an altitude zk+1 of the other point among the neighboring estimated reference points and that of the terrain corresponding thereto have different signs; and (d) determining that the actual position of the target exists between the searched estimated reference points Pk.
