Abstract
Disclosed are a calibration device for non-contact photographic hole measurement and a calibration method for non-contact photographic hole measurement. The device includes a base, an installation platform, a calibration assembly and an illumination compensator. The installation platform is provided at the base, and the calibration assembly is provided at the installation platform. In a calibration process, the base drives the installation platform to rotate around a Z axis, thereby driving the calibration assembly to rotate around the Z axis. At the same time, the installation platform drives the calibration assembly to rotate around an X axis. The illumination compensator is configured to fill light for a camera during a photography process.
