1. A system comprising:
a camera disposed at a distance from a calibration field that is less than a hyperfocal distance of the camera; and
at least one processor configured to:
receive, from the camera, one or more captured images of the calibration field, the one or more captured images including multiple characteristic points within the calibration field;
determine respective centers of the characteristic points in each captured image;
determine, based on the respective centers of the characteristic points in each captured image, respective positions of the characteristic points relative to the camera in each captured image; and
calibrate the camera based on the positions of the characteristic points in each captured image.
