Abstract

The invention discloses a method and device of aero-photography field work. The method comprises the following steps: according to the range of measuring zone, obtaining the DEM data of a region to be measured; obtaining the intersection point between an initial air line direction and the measuring zone so as to determine the start point coordinate and the end point coordinate of the air line; setting the start point coordinate as the initial exposure point of the air line, according to the DEM data, calculating the coordinates of each exposure point in the air line in sequence until the calculated coordinate of the current exposure point is larger than the coordinate of the end point of the air line, determining the current exposure point as the last exposure point of the air line; taking the air line as the initial air line, laying air lines in sequence by taking the overlapping degree, which is calculated according to the DEM data, as the constraint until the lateral direction coordinate value of the current air line is not in the range of maximal coordinate value and minimal coordinate value of the lateral direction of the measuring zone, and determining the current air line as the last air line in the measuring zone.

Description

technical field [0001] The invention relates to the field of aerial photogrammetry, in particular to a method and device for aerial photogrammetry. Background technique [0002] When designing routes and exposure points for traditional area-scan camera aerial photography, generally one-half of the sum of the average elevations of several representative ground high points and the average elevations of ground low points in the shooting area is used as the datum elevation, or manually estimated Input the datum elevation of this place; based on this datum, according to the ground resolution required in the survey area, the focal length of the camera and the CCD (Charge-coupled Device) pixel size, the size of the CCD area array, and the lateral and heading overlap Determine the relative flight height and absolute flight height, course distance and side distance of the route; design the route based on the fixed side distance, generate the exposure point position based on the fixed...
