Title:
METHOD FOR STEREOSCOPICALLY MEASURING IMAGE POINTS AND DEVICE FOR CARRYING OUT SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2005/103616
Kind Code:
A1
Abstract:
The invention relates to stereometry and can be used for photogrammetry, medicine, building engineering, for assessing risks of natural and technogenic disasters and the effects thereof and for othres purposes. The inventive method consists in building a stereoscopic model based on two overlapping images, in determining the position of the aiming axis of eyes during stereoscopic perception of said model, in recording observation results at eyes fixation moments, in computing the projection of the sight fixation area on a monitor screen and in automatically selecting object characteristic points on stereoimage fragments corresponding to said areas. The conjugate characteristic points of the observed object selected on said fragments are identified for the left and right eye by time synchronisation and are adjusted according to a condition of corresponding rays intersection determined by a vectors complanarity equation. The visual control is carried out during measurements by imprinting colour markers and modifying the colour parameters of the image area which corresponds to given a fixation.
