Abstract

The invention relates to an image acquisition method and device and a nonvolatile computer readable storage medium, and relates to the technical field of image processing. The method comprises the following steps: acquiring relative displacement between a to-be-detected article and an image acquisition device at each moment; under the condition that the relative displacement is consistent with the displacement parameter, acquiring a sub-image of the to-be-detected article by using an image acquisition device at the moment corresponding to the relative displacement; and determining a detection image of the to-be-detected article according to the plurality of collected sub-images.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image acquisition method, an image acquisition device, and a non-volatile computer-readable storage medium. Background technique [0002] Image scanning technology can be applied to various technical fields. In a security inspection device based on a radiographic imaging system, images of items may be collected multiple times at different times to obtain a complete inspection image. [0003] In related technologies, the moment of image acquisition is determined according to the relative speed between the ray source and the object to be detected. Contents of the invention [0004] The inventors of the present disclosure have found the following problems in the above-mentioned related technologies: the accuracy of the image depends on the stability of the relative speed, which makes the detection image prone to deformation, resulting in a decrease in the...
