POSITION ESTIMATION SYSTEM, POSITION ESTIMATION METHOD, AND COMPUTER PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18029768 titled 'POSITION ESTIMATION SYSTEM, POSITION ESTIMATION METHOD, AND COMPUTER PROGRAM

Simplified Explanation

The patent application describes a position estimation system that can accurately determine the position of a target relative to an imaging unit.

  • The system includes an image acquisition unit that captures an image of a reflecting unit, which is located within the imaging range of the imaging unit.
  • A first estimation unit uses the image to estimate the position of the reflecting unit relative to the imaging unit.
  • A second estimation unit then uses the image and the first relative position to estimate the position of the target relative to the imaging unit.
  • This system allows for proper estimation of the positional relationship between the imaging unit and the target.


Original Abstract Submitted

A position estimation system includes: an image acquisition unit that obtains an image for estimation including a target that is disposed out of an imaging range of an imaging unit, by imaging a reflecting unit that reflects a light and that is disposed in the imaging range of the imaging unit; a first estimation unit that estimates a first relative position that is a position of the reflecting unit with respect to the imaging unit, on the basis of the image for estimation; and a second estimation unit that estimates a second relative position that is a position of the target with respect to the imaging unit, on the basis of the image for estimation and the first relative position. According to such a position estimation system, it is possible to properly estimate a positional relationship between the imaging unit and the target.
