Abstract
A high-precision positioning result in self-positioning is provided. An information processing apparatus acquires a first coordinate position inside an image of each light source included in an image captured with an imaging device among multiple light sources whose coordinate positions are known in a three-dimensional space to derive at least a coordinate position or an orientation of an own device in the three-dimensional space based on a coordinate position of the light source included in the image in the three-dimensional space and the first coordinate position. The apparatus estimates a height of the imaging device in the three-dimensional space to perform positioning processing using information on the estimated height of the imaging device, acquires a second coordinate position of the light source on the image corresponding to the positioning processing result, and corrects the height of the imaging device based on the first coordinate position and the second coordinate position.
