Abstract:
An image capture position and direction estimation device includes a region determination unit that determines a plurality of regions to be associated between a query image and an image with position and direction, a depth estimation unit that estimates a depth of each region, and an image capture position and direction estimation unit that estimates a direction in the region with a large depth estimated by the depth estimation unit and estimates a position in the region with a small depth estimated by the depth estimation unit.
