Abstract: The present disclosure discloses a method, an apparatus and a system for reconstructing an image of a three-dimensional surface. The method comprises the following steps of: constructing a three-dimensional model of the three-dimensional surface using X-ray imaging data obtained by imaging the three-dimensional surface with X-ray and extracting three-dimensional coordinate parameters of feature points; constructing one or more two-dimensional posture images of the three-dimensional surface using visible light imaging data obtained by imaging the three-dimensional surface with visible lights, and extracting two-dimensional coordinate parameters of feature points from each of the two-dimensional posture images; establishing a mapping relationship between the two-dimensional posture image and the three-dimensional model by matching the three-dimensional coordinate parameters and the two dimensional coordinate parameters of the feature points in each of the two-dimensional posture image; and filling the one or more two-dimensional posture image onto the three-dimensional model utilizing the mapping relationship established for each of the two dimensional posture images to form a reconstructed image of the three-dimensional surface, wherein the X-ray imaging data and the visible light imaging data of the three-dimensional surface along the same orientation are simultaneously captured.

Abstract: The present disclosure discloses an image display method in a CT system. The method comprises: implementing CT scanning on an inspected object, to obtain CT projection data; organizing the CT projection data according to a predetermined interval; extracting basic data from the organized CT projection data by using a fixed angle as a start angle and using 360 degrees as an interval; forming a DR image based on the extracted basic data; reconstructing a three-dimensional image of the inspected object from the CT projection data; and displaying the DR image and the reconstructed three-dimensional image on a screen at the same time. In the solution, the CT data is processed to obtain DR data. After the DR data is obtained, a DR image is obtained directly using a DR data processing algorithm. This enables an image recognizer to more accurately and more rapidly inspect goods carried by a passenger using the existing experience in image recognition of the DR image.
