Information processing method and apparatus

An information processing method performed by an information processing apparatus including a processor, the information processing method comprising:

• a first image inputting step of inputting a first image captured by an imaging apparatus mounted on an object body and configured to capture a physical space;
• a second image inputting step of inputting a second image captured by an image capture unit configured to capture the object body from an outside-in view position;
• a first detecting step, performed by the processor of detecting a feature quantity relating to image coordinates of a first index in the physical space, based on the first image input in the first image inputting step;
