Position estimating method, position estimating system, and position estimating apparatus

A position estimating system comprising:

• a control apparatus configured to control moving of a moving object;
• an imaging apparatus configured to capture an image of the moving object;
• and
• a position estimating apparatus configured to estimate position information for the moving object, wherein
• the position estimating apparatus includes
• a memory storing instructions;
• and
• one or more processors configured to execute the instructions to:
• obtain an image coordinate representing an image position of a moving object in an image captured by the imaging apparatus, and
• convert the image coordinate for the moving object to a real space coordinate for the moving object, based on information obtained from a correspondence between real space coordinate information indicating a predetermined point in a real space and image coordinate information representing the predetermined point.
