Patent Searching and Data


Title:
NAVIGATION DEVICE AND SURVEY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/042907
Kind Code:
A1
Abstract:
In the present invention, image matching of a pair of image data sets respectively captured at different imaging positions is performed to search for a point corresponding to the coordinates of a ranging point on the image of one of the pair of image data sets from the image of the other of the pair of image data sets. The attitude of an aircraft (2) is estimated by correcting the value of a parameter indicating the attitude of the aircraft (2) so that the difference between the coordinates of the ranging point on the image of the other of the pair of image data sets and the coordinates of the corresponding point searched for by the image matching decreases.
