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.

Abstract: Disclosed are a point cloud model processing method and apparatus, and a readable storage medium. The method includes: acquiring a target image pair and first and second neighborhood images corresponding to the target image pair from first and second image sets photographed for a target scene with different visual effects; performing a calculation to obtain a merge parameter based on the relationship among the target image pair, the first neighborhood image, the second neighborhood image, a first point cloud model, and a second point cloud model; and merging the first point cloud model and the second point cloud model based on the merge parameter to obtain a target point cloud model for reconstructing a three-dimensional structure of the target scene.
