Prism assembly of inclination measurement camera

The invention relates to the field of optical-mechanical structures, in particular to a prism assembly of an oblique measurement camera, which comprises a first light splitting surface and a second light splitting surface which are arranged on a prism and used for splitting light beams, the first light splitting surface is obliquely arranged on an intersection surface of a transverse edge and a vertical edge, and the second light splitting surface is arranged on the vertical edge of the prism. And the first beam splitting surface and the second beam splitting surface are obliquely arranged in opposite directions. A first through hole is formed in the bottom face of the prism table, and a second through hole is formed in the back face of the prism table. During use, light is emitted into the prism from the first through hole, and is emitted out from the top of the prism, one side, far away from the prism table and away from the rear surface, of the transverse edge and from the second through ...
