An apparent displacement of the position of a body with respect to a reference point or system, caused by a shift in the point of observation.
由观测点偏移引起的某物体位置相对参照点或参照系的视位移。
parallax: absolute stereoscopic

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.
NULL
parallax: angular
角视差
See PARALLACTIC ANGLE.
参见parallactic angle(视差角)。
parallax: annual
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.
以天体为顶点的、地球轨道半径所对的角。也称作heliocentric parallax(日心视差)或stellar parallax(恒星视差)。
parallax: diurnal

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.
NULL
parallax: geocentric
地心视差
See PARALLAX: DIURNAL.
参见diurnal parallax(周日视差)。
parallax: heliocentric
日心视差
See PARALLAX: ANNUAL.
参见annual parallax(周年视差)。
parallax: horizontal
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。
parallax: instrumental (or instrument)

That change which may result from the position in which an obser­ver stands with respect to the FIDUCIAL MARKS on an instru­ment (personal parallax); or by the imperfect ADJUSTMENT of the optics of the instru­ment (optical parallax).
NULL
parallax: linear

parallax: solar
太阳视差
The E­QUATORIAL HORIZONTAL PARALLAX of the SUN.
太阳的赤道地平视差。
parallax: vertical

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.
