The 3rd step, determines that in image primitive, number of pixels is n× n,single pixel wide is r, according to formula k h = round([ d s -( m-1) p]/ r) and k h '= round( d t / r) obtain respectively monocular finding in horizontal direction mtotal pixel difference of individual image primitive k h horizontal pixel difference with the same image primitive of binocular finding k h ', wherein function round () represents round;
The 4th step, adopts in vertical direction and second and the identical method of the 3rd step, obtains monocular finding in vertical direction ntotal pixel difference of individual image primitive k v vertical pixel difference with the same image primitive of binocular finding k v ';
The 5th step, by l>2 f( m-1), k h < m, k v < n, by this m× nindividual image primitive is divided into k h × k v individual piece, each comprises round( m/ k h ) × round( n/k v ) individual image primitive, the piece of last column and row may be owing to not dividing equally more than or be less than round( m/ k h ) × round( n/k v ) individual image primitive, division result is as shown in Figure 4;
The 6th step, the same position of the each image primitive from a piece is extracted k h ' × k v ' continuous pixel, obtain extracting pixel, position skew 1 pixel unit of the extraction pixel of image primitive in image primitive in adjacent two pieces, this side-play amount has same tropism, be the extraction pixel-shift schematic diagram of adjacent 4 pieces as shown in Figure 5, thereby form, extract micro-pattern matrix;
The 7th step, carries out integration imaging demonstration by micro-extraction pattern matrix, show that stereo-picture only has specific direction visible, and other directional image disappears, and realizes integration imaging directivity and shows.
The present invention has realized integration imaging directivity and has shown, has reduced the data volume of micro-pattern matrix Pixel Information simultaneously.
