摘要

Monochromatic stereoscopic head of variable divergence. The device consists of an arrangement of prisms, filters and gears to generate on a single image sensor, field camera or linear, indistinctly, a stereopteran formed by two images corresponding to two simultaneous projections of the same scene with a different point of view, the angle of divergence being adjustable. Variable divergence is achieved with two pairs of optical wedges whose position is adjusted with a gear system. Two rhomboid prisms laterally displace the exit of the wedges to place them on the half-planes of the sensor. Monochromatic filters prevent dispersion in wedges. The device is applicable in artificial vision and photogrammetry, and solves the problems of alignment and calibration due to spatial, temporal and radiometric differences derived from the use of different image sensors for the same stereopar, which make it difficult to reconstruct three-dimensional models of objects and terrains.
