Distance estimation apparatus, system, distance estimation method, and computer program

摘要

Provided is a technique for estimating a distance to a position of a measurement object from a plurality of imaging devices with high accuracy even if the distance between imaging devices is variable. The distance estimation device includes a first imaging device that photographs a first image and a second imaging device that photographs a second image in a second imaging range at least a part of which overlaps a first imaging range photographed by the first imaging device, A first distance estimating means for estimating a first distance which is a distance between the first image capturing apparatus and the second image capturing apparatus which captures the image at the timing synchronized with the image capturing timing of the image capturing apparatus, A reference position based on a positional relationship between the first imaging device and the second imaging device and a reference position based on a positional relationship between the first position and the second position on the basis of the correspondence relationship with the second position in the image and the first distance And a second distance estimation unit that estimates a second distance that is a distance between the position on the corresponding real space and the position on the corresponding real space.
