Position / orientation estimation apparatus, image processing apparatus, and position / orientation estimation method

摘要

The present invention makes it possible to enhance the accuracy of position and attitude estimation. A position and attitude estimation device (10) is provided with a first detection unit (1) for detecting a plurality of first position and attitude parameters pertaining to the position and attitude of a moving object, a first position and attitude estimation unit (2) for estimating a first position and attitude of the moving object at a first time on the basis of the plurality of detected first position and attitude parameters, a second detection unit (3) for detecting a plurality of second position and attitude parameters pertaining to the position and attitude of the moving object, a second position and attitude estimation unit (4) for estimating a second position and attitude of the moving object at a second time different from the first time on the basis of the plurality of detected second position and attitude parameters, and a position and attitude output unit (5) for outputting a third position and attitude on the basis of the estimated first position and attitude and second position and attitude.
