Abstract
Embodiments of the present disclosure relate to a calibration verification method for a camera intrinsic parameter, an apparatus, a device, and a medium. The method includes: acquiring a plurality of reference images photographed by a target camera with a plurality of reference world coordinates under a preset photographing condition, wherein the camera intrinsic parameter of the target camera is calibrated; determining, a first coordinate change parameter corresponding to the plurality of reference world coordinates according to the preset photographing condition, and determining a second coordinate change parameter of the plurality of reference images according to a preset algorithm; determining whether the second coordinate change parameter is consistent with the first coordinate change parameter; and if the second coordinate change parameter is consistent with the first coordinate change parameter, feeding back a verification message indicating successful calibration of the camera intrinsic parameter.
