Abstract
A method for estimating orientation includes: executing a detection process that includes detecting multiple line segments from each of multiple images included in a video image captured by an imaging device; executing an estimation process that includes estimating a first inclination that is an inclination of a line segment that is among the multiple line segments and detected from a central region including a center of an image among the multiple images; and associating the first inclination with a vertical direction in a three-dimensional space to estimate an orientation of the imaging device.

A method for estimating orientation, comprising:
- executing a detection process that includes detecting multiple line segments from each of multiple images included in a video image captured by an imaging device;
- executing an estimation process that includes
- estimating a first inclination that is an inclination of a line segment that is among the multiple line segments and detected from a central region including a center of an image among the multiple images;
- and
- associating the first inclination with a vertical direction in a three-dimensional space to estimate an orientation of the imaging device.
A apparatus for estimating orientation, comprising:
- a memory;
- and
- processor circuitry coupled to the memory, the processor circuitry being configured to
- execute a detection process that includes detecting multiple line segments from each of multiple images included in a video image captured by an imaging device;
- execute an estimation process that includes
- estimating a first inclination that is an inclination of a line segment that is among the multiple line segments and detected from a central region including a center of an image among the multiple images;
- and
- associating the first inclination with a vertical direction in a three-dimensional space to estimate an orientation of the imaging device.
A non-transitory computer-readable storage medium for storing a program that causes a processor to execute a process for estimating orientation, the process comprising:
- executing a detection process that includes detecting multiple line segments from each of multiple images included in a video image captured by an imaging device;
- executing an estimation process that includes
- estimating a first inclination that is an inclination of a line segment that is among the multiple line segments and detected from a central region including a center of an image among the multiple images;
