Description

one

The invention relates to the field of photogrammetry and is intended to interpret stereoscopic-pair of images in various formats located on a non-focal film.

A stereo1 SPR-3M projector for O6piai6oTKH stereo pairs {, in which stereo pairs are mounted on moving carriages of a stereo projector and are shifted in the course of measurements relative to fixed marbs, is known. This device is cumbersome, complicated to adjust, and does not allow graphic work to be performed during image processing.

These drawbacks are absent in measuring stereoscopes, where measuring marks alternate in the process of processing stereopairs.

A stereoscopic measuring stereoscope containing a device for altering the ocular basis, the ocular, changing lenses, mirrors, a device for measuring the parallax difference is known. Xenon points of images with the same name, executed in the form of mobile light marks associated with me: K13ometric measuring devices 2.

However, this stereoscope does not allow processing of stereopair images on uncut films, since they are often released into each other.

The aim of the invention is to provide an opportunity to perform graphically works during measurements on roll films.

This goal is achieved by the fact that, in the proposed stereo-oop, the moving light marks are made to rotate in ocular parts, the image of the marks is optically matched to the object plane of the oculars, and prism image rotation systems are introduced into the objective parts.

The drawing shows an optical stereo box. The stereoscope contains systems of movable mirrors 1, 2, 5, interchangeable lenses 4, 5, image rotation nodes, for example, Pekhan's prisms, the ocular part including the oculi 7, rhombic prisms 8 connected to rectangular prisms 9 through beam splitting coatings, light marks 10, whose images are projected into the object planes of the eye 7 through lenses 11, 12 and prisms 13, 14. Objectives // w. 12, forming an image of a lacquer, a DETAILED magnification, coinciding with the scale of the branch projecting the images, which makes it possible to determine by the magnitude of the displacement of marks the dimensions of the object considered in the photograph and measure the difference of parallaxes. Depending on the format of the processed aerofilm stereosco base ;; ; ina; vyprlnend. It does not have to be replaced by the Euves' system by moving (removing it or removing) the mirror system 1, 2 of the left branch relative to the right (along the AA line}. To maintain the sharpness of the image, WebWereocKon images are made using a separate WL-5G packet, TTS, and the heat of the circuit. It is equivalent in terms of the equivalent of the system of the mirrors /, 2 (via line 55). Movable light bulbs from the mark 0 are equipped with a microcircuit screening device and installed with possible 7 tT & paSBOpiOTa around the optical axis. , left-marks at 90 ° and e It is possible to compensate for the loopy parallaxes, and the longitudinal displacement of the right pS ys nsMepliTb npojiojibibyyStratlXaxi, ... / G to work; ki on an uncut film are placed on the object plane 15 of the stereoscope and 1 veteran 15. The image / taken from a mirror 1, 2, 3, one of the equivalent lenses 4 or, 5, the Pehan 6 prism and the rhombic prism 8 are fed into the Object plane the oculipus 7. There, through the rectangular rim 9 and the beam-splitting face of the prism S, an image is received under the low light of the slanting mark 10. By moving the mirrors 1, 2.

By rotating Pekhan’s prisms 6 images of the stereo are oriented; they are perfect for superficial observation of the terrain model. It is allowed by this pattern. mirrors / and 2 to eliminate the longitudinal ghosting of the stereo model and the unbroken spread of the entire system of the stereo image of the airfilm images to eliminate the cases of transverse ghosting..:: -,.:.::,:.;. By moving the mark using the migrometer The horizontal BHHfa achieves the alignment of the stereoscopic image of the mark with the measured point of the stereo pair (stereo model).

f - "irts--", microm.meters are read. In the case of a transverse parallax in a stereoscopic image of the mark, the measuring device of the left mark is rotated by 90 °. Doubling (along the parallax) is eliminated by longitudinal movement. Similarly, the measurement is carried out for another point of the stereo model. The resulting sample difference (the difference of the longitudinal parallaxes) makes it possible to determine the magnitude of the excess of the locality point of the terrain na other way. The measuring stereo cleavage of such a system allows measurements with high accuracy at relatively small gabars, and it has the mass and weight of the instrument. Simultaneously with stereoscopic decoding of images (recognition, metering, objects, etc.). On a remote stereo, it is possible to simultaneously apply and lower the results of the treatment, i.e., to perform graphic work on nano-erasable lenses. All this allows you to quickly obtain the necessary information and eliminate the operation of preliminary drawing yellow images from the roll film. : F o m u l a, and 3 o barre n i.
