Abstract:
1. A multiple view angle X-ray stereoscopic imaging method comprising the steps of: 1) obtaining the parameters of an imaging system by a method of measuring or calibrating; 2) projected image sampling: rotating a digital imaging acquisition device or an object placed in the same and making the digital imaging acquisition device and said object to generate relative circular movement or spiral movement, and acquiring a projected image G 3) establishing image indexes: establishing two level sorted indexes for all image pixels based on the parameters of the imaging system; 4) setting viewpoint parameters: setting the viewpoint parameters of stereograms, by user, through an interactive interface according to the observation requirement in order to obtain stereograms having observation effects of different angles; 5) calculating sight line parameters: calculating the parameters of the corresponding sight line for each pixel in an image, said viewpoint parameters determine a current stereogram; 6) image indexes looking up: looking up the ray beams near to said sight line parameters in the image index table established in step 3), based on said sight line parameters calculated in step 5); 7) pixel combining: employing one or more various filtering interpolation methods to implement the interpolation combination calculations for the near ray beams and combining an image pixel (p′(i,j)) corresponding to a sight line (L′ 8) image processing: implementing enhancement processing for images through an interactive interface according to the requirements of user; 9) stereoscopic displaying: realizing display of stereograms by a stereoscopic display device such that the left eye of the user can see only the image corresponding to the view angle of left eye and the right eye of the user can see only the other image corresponding to the view angle of right eye, and that thereby a stereoscopic image is formed.
