Anaglyph stereo presentation is a new form of aerospace education Zinchuk N.N. , Knizhnikov Yu.F. , Kharkovets E.G. ,
Anaglyph method of a visual perception of 3-D images consists of:
- simultaneous presentation of the complement images of stereomate (left image of the red color, right image of the blue color);
- next following visual perception of these images through the left red filter and through the right blue filter.
At present, practical using of this well-known method is developed for remote aerospace education. A stereomate of the anaglyph images is projecting to the screen from display of digital photogrammetric equipment. And multiple audience (for example, student group) can simultaneously visual percept of 3-D model and measuring cursor through elemental color filters (color glass). It is very important because traditional photogrammetric equipment has oriented for alone operators.
The main task of the preparation of educational photogrammetric stereo presentation includes of constructing of anaglyph stereomate on computer display and it s projecting to the demonstrating screen for the purpose of the forming of projected stereo model. The method of the forming of the best quality photogrammetric anaglyph stereomate has been developed in laboratory of aerospace methods of the Moscow State University. This method consists of:
- formation of the stereomate from initial digital images or from analog-to-digital conversion of aerospace photo images;
- accounting of the parameters of digital image pixel, estimation of the optimal measurement of longitudinal parallaxes for the best visual stereo perception, mutual geometrical correction of the digital stereomate images;
- formation of the digital anaglyph images and their color correction, mutual orientation of the digital anaglyph images, constructing of the digital anaglyph stereomates;
- estimation and production of the optimal conditions of anaglyph stereo presentation.
Some important and interesting results were obtained by proposed method for the organization of the education process of the aerospace disciplines.
