1. A CT scanning method, comprising:
determining, according to dual-camera images of a part to be scanned, a first coordinate of a mark point of the part to be imaged in a dual-camera coordinate system;
converting the first coordinate into a second coordinate of the mark point in a CT coordinate system according to coordinate system transformation parameters;
generating first locating information according to the second coordinate to drive a scanning table to move to a first location designated by the first locating information;
obtaining projection images of the part to be scanned, wherein the projection images comprises a front-back direction projection image and a side-side direction projection image for the part to be scanned;
determining second locating information and scanning information of the part to be scanned according to the projection images, wherein the scanning information comprises scanning region information and exposure parameter information; and
driving the scanning table to move to a second location designated by the second locating information according to the second locating information and performing CT scanning according to the scanning information.
