Object three-dimensional perspective imaging method and system

Abstract

The invention belongs to the perspective imaging field, and relates to an object three-dimensional perspective imaging system and imaging method. The object three-dimensional perspective imaging system includes a ray transmitter (1), an objective table (2), a lens group (3), a mechanical support (4) and a processing end (5), wherein the ray transmitter (1) and the lens group (3) are respectively fixed at two ends of the mechanical support (4); the objective table (2) is movably arranged on the mechanical support (4); the objective table (2) is provided with a self-rotation motor (21); the processing end (5) is in electric-signal-connection with the ray transmitter (1) and the lens group (3); and the lens group (3) and the processing end (5) are in electric-signal-connection with the objective table (2). The object three-dimensional perspective imaging system has the advantages of being small in volume, being convenient to carry, being simple in operation, having no demand for frequent operation, being clear in imaging and being low in price.

The existing 3D CT imaging system obtains a series of data by spirally scanning the object through X-rays, or divides multiple cameras at different angles, and then performs 3D reconstruction of the acquired series of data. The existing 3D CT imaging system Large size, no portable flexibility, and large-scale CT equipment uses large-size digital CCD panels for imaging, because large-size CCDs are expensive, which directly leads to a sharp increase in the manufacturing cost of CT imaging equipment. Therefore, it is necessary to purchase a set of large-scale CT Imaging equipment requires millions of dollars, which is not conducive to the promotion and use of small and medium-sized research institutes, companies, and medical institutions

[0003] The imaging processing algorithm of the traditional imaging algorithm mostly uses the Laplacian pyramid to perform Fourier transformation according to the spatial frequency layer in the realization of the noise reduction function. Some important image content and details are removed, and the traditional imaging processing algorithm image denoising and enhancement are processed separately, so the imaging speed is slow
