Processing apparatus, processing method, and storage medium for calibrating an image capture apparatus

A processing method for calibrating an image capture apparatus having a first optical system, a second optical system, and an image capture sensor, each of the first and second optical systems including a wide-angle lens next to each other, the processing method comprising:

• obtaining a first image acquired by image capture based on a light beam passing through the first optical system using the image capture sensor, the first image including a part of the second optical system;
• and
• determining, based on an image of the second optical system included in the first image as an object and not based on an image captured by the second optical system, a first calibration parameter for calibrating the first optical system according to a deviation from a reference value related to the first optical system or the image capture sensor,
• wherein an angle of view of the wide-angle lens of the first optical system is an angle that provides the ability to capture at least part of the second optical system as the object.

A non-transitory computer readable storage medium storing a program which causes a computer to perform a processing method for calibrating an image capture apparatus having a first optical system, a second optical system, and an image capture sensor, each of the first and second optical systems including a wide-angle lens next to each other, the processing method comprising:

• obtaining a first image acquired by image capture based on a light beam passing through the first optical system using the image capture sensor, the first image including a part of the second optical system;
• and
• determining, based on an image of the second optical system included in the first image as an object and not based on an image captured by the second optical system, a first calibration parameter for calibrating the first optical system according to a deviation from a reference value related to the first optical system or the image capture sensor,
• wherein an angle of view of the wide-angle lens of the first optical system is an angle that provides the ability to capture at least part of the second optical system as the object.
