In PHOTOGRAMMETRY, considering a pair of AERIAL PHOTOGRAPHS of equal PRINCIPAL DISTANCE, the algebraic difference of the distances of the two IMAGES from their respective PHOTOGRAPH NADIRS, measured in a horizontal plane and parallel to the AIR BASE. Also called horizontal parallax, linear parallax,or x-parallax.

周年视差
The angle subtended at a CELESTIAL BODY by the radius of EARTH's ORBIT. Also called helio­cen­tric parallax, or stellar parallax.

The difference in the apparent direc­tion or position of a CELESTIAL BODY as observed from the centre of the EARTH and a point on its sur­face. This varies with the body's ALTITUDE and di­stance from the EARTH. Also called geocentric paral­lax.

从地心或者地面上一点观测到的星球视运动或者位置的差异。它随着星球的高度和与地球的距离变化而变化。亦称为geocentric parallax(地心视差)。
parallax: equatorial horizontal
NULL
HORIZONTAL PARALLAX as observed at the EQUATOR, as it attains its maximum value.

水平视差
In ASTRONOMY, the GEOCENTRIC PARALLAX of a body on the observer's HORIZON. In PHOTOGRAMMETRY, PARAL­LAX: ABSOLUTE STEREOSCOPIC.
在天文学中,指在观测者地平线上某一天体的地心视差。在摄影测量学中指绝对立体视差。

In PHOTOGRAM­METRY, the difference between the perpendicular distances of the two IMAGES of a point on a pair of photographs from the vertical plane containing the AIR BASE. The existence of y-parallax is an indication of TILT in either or both PHOTOGRAPHS and/or a difference in flight heights, and interferes with stereoscopic examination of the pair. Also called vertical parallax or want of correspondence.
