Computer-readable recording medium storing position measuring program, information processing device, and position measuring method

An information processing device comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to perform processing including:
• identifying a first position of a first measurement target in image data received from an imaging device;
• identifying specific identification information and a specific type that correspond to a specific position at which a positional relationship with the first position satisfies a first condition, by referring to a first storage device coupled to the computer, the first storage device being configured to store a position of each measurement target, identification information on the imaging device that has captured the image data in which each measurement target appears, and a type of each measurement target, in association with each other;
• identifying a specific feature point group that correspond to the identified specific identification information and the identified specific type, by referring to a second storage device coupled to the computer, the second storage device being configured to store the identification information on the imaging device that has captured the image data in which each measurement target appears, the type of each measurement target, and a feature point group of each measurement target in the image data in which each measurement target appears, in association with each other;
• and
• estimating a posture of the first measurement target from the identified specific feature point group.

A position measuring method implemented by a computer, the position measuring method comprising:

• identifying a first position of a first measurement target in image data received from an imaging device;
• identifying specific identification information and a specific type that correspond to a specific position at which a positional relationship with the first position satisfies a first condition, by referring to a first storage device coupled to the computer, the first storage device being configured to store a position of each measurement target, identification information on the imaging device that has captured the image data in which each measurement target appears, and a type of each measurement target, in association with each other;
• identifying a specific feature point group that correspond to the identified specific identification information and the identified specific type, by referring to a second storage device coupled to the computer, the second storage device being configured to store the identification information on the imaging device that has captured the image data in which each measurement target appears, the type of each measurement target, and a feature point group of each measurement target in the image data in which each measurement target appears, in association with each other;
• and
• estimating a posture of the first measurement target from the identified specific feature point group.
