[0034] Example 1: An example of an orbital photogrammetry method
[0035] See figure 1 As shown, an embodiment of an orbit photogrammetry method provided by the present invention includes:
[0036] Step S110: irradiate the traveling track with a planar laser beam including two or more parallel in-line sub-beams;
[0037] Step S120, using the spot image of the inline sub-beam to determine the relative position between points on the traveling track or the coordinates of the points on the traveling track.
[0038] In this embodiment, the optical measurement mark serves as the measurement control point.
[0039] Generally, four or more measurement control points are arranged in a scene covered by an optical imaging picture. Typically, four to sixteen measurement control points are arranged. If there are more measurement control points, the measurement error is small.
[0040] The optical measurement indicator, receiving the control information through a wired channel or a wireless channel, a...
Example Embodiment
[0136] Embodiment two, an example of a photogrammetric device
[0137] See figure 2 As shown, an embodiment of a photogrammetric device provided by the present invention includes:
[0138] Irradiation module 210, measurement module 220; among them,
[0139] The irradiation module 210 is used to irradiate the traveling track with a planar laser beam containing two or more parallel in-line sub-beams, including a laser light source sub-module, a laser beam shaping sub-module, a laser reflection surface sub-module, and irradiation control At least one of a sub-module, an irradiation position information acquisition sub-module, and a laser reflection surface rotation servo sub-module;
[0140] The measurement module 220 is used to determine the relative position between points on the traveling track or the coordinates of the points on the traveling track using the spot image of the inline sub-beam, and includes at least one of a spot image processing submodule and a position information ...
