Abstract

The invention discloses a measurement method and an arithmetic facility of an azimuth angle from a photographing centre to an objective physical point. The distance from a horizontal line of an image point to a plumb line of the photographing centre is determined by using a value of vertical offset, a principal distance and an inclination angle of a principal optic axis; an anti-trigonometric function (for example, an arctan function) of the ratio between the sum of the azimuth angle of a principal vertical plane and horizontal offset and the value of the distance from the horizontal line of the image point to the plumb line of the photographing centre is equal to the azimuth angle from the photographing centre to the objective physical point. The arithmetic facility with a formula is designed.

Description

Technical field [0001] The invention relates to a method for measuring the azimuth angle from a photography center to a target physical point, which belongs to the field of surveying and mapping, and also belongs to the field of aerial photogrammetry or close-range photogrammetry with balloons as carriers, and relates to the measurement from the photography center to the field of close-range photogrammetry during the photogrammetry operation process. The method of the azimuth angle of the physical point corresponding to the image point. Background technique [0002] Have not yet consulted the data of this background technology at present. Contents of the invention [0003] In order to utilize the photographed sheet to obtain the azimuth angle from the photographic center to the corresponding physical point of the image point, the present invention provides a method for measuring the azimuth angle from the photographic center to the target physical point, by which the corre...
