In this exciting time of increasingly powerful computer tools only few imaginable things are left to be invented. Recently issued PC multimedia operating system Vista supports speech and hand writing recognition, visual and data streaming and networking, as well as traditional computer powers. Present invention is meant to fulfill the only gap left in computer abilities: which is comprehensive general purpose three-dimensional vision to enable computers to see the world they have changed so much. The main feature of this invention is an advanced and powerful image preprocessing method and apparatus supporting thereof.
We claim: 1. An apparatus comprising: at least two image sensors, each having an optical center and light sensing elements arranged in rows and columns, said image sensors positioned in such a way that the rows of the sensing elements are parallel to a line connecting the optical centers; means to
We claim: 1. An apparatus comprising: at least two image sensors, each having an optical center and light sensing elements arranged in rows and columns, said image sensors positioned in such a way that the rows of the sensing elements are parallel to a line connecting the optical centers; means to compare and process images received from said image sensors. 2. The apparatus from claim 1 wherein the image sensors are synchronized to take images simultaneously. 3. The apparatus from claim 1 wherein the image sensors lie on the same plane. 4. The apparatus from claim 1 having lenses, one per each image sensor. 5. The apparatus from claim 4 wherein optical axes of the lenses are parallel. 6. The apparatus from claim 1 wherein the image sensors are identical. 7. The apparatus from claim 1 wherein the image sensors are digital cameras. 8. The apparatus from claim 1 having a computer interface. 9. The apparatus from claim 1 wherein images from the image sensors are identical when taken at infinity. 10. The apparatus from claim 1 having means to compare and process data from corresponding rows of the light sensing elements of said image sensors. 11. The apparatus from claim 10 having means to calculate distance from the apparatus to an object in its field of view as a function of an apparent shift of the object within the images of said sensors by comparing and processing data of the sensing elements from corresponding rows of these image sensors. 12. The apparatus from claim 1 having means to identify brightness step marks in images of the image sensors, calculate shift between corresponding marks in images of the image sensors, and transmit this data to a computer. 13. The apparatus from claim 12 having means to combine the brightness step marks into contours. 14. The apparatus from claim 1 having means to calculate 3-D coordinates of objects. 15. A method for instant calculation of distances to objects by processing images received from an apparatus having two image sensors, each having an optical center and mounted in such a way that rows of their light sensing elements are parallel to a line connecting the optical centers, comprising the steps of: obtaining images by the two sensors with overlapping view areas; finding brightness step marks in the images; determining the same marks in the corresponding rows of the light sensing elements of the image sensors; calculating a shift between the same marks in the corresponding rows of the light sensing elements of the image sensors; calculating distance to the object's mark equal to the distance between the optical centers of the image sensors divided by the shift and multiplied by the focus. 16. A method for instant calculation of distances to objects by processing images received from an apparatus having two image sensors, each having an optical center and mounted in such a way that rows of their light sensing elements are parallel to a line connecting the optical centers, comprising the steps of: obtaining images by the two sensors with overlapping view areas; calculating a brightness step mark in a row of light sensing elements of one of the image sensors; finding an identical brightness step mark in a corresponding row of the light sensing elements of the other image sensor; calculating a positional difference between said brightness step marks in the corresponding rows of the light sensing elements of those image sensors; assigning the distance value corresponding to said positional difference.
