9. A vector geographic information acquisition method based on remote sensing images is characterized by comprising the following steps:
s1, firstly, adjusting the height of the triangular support (2) according to the height of a geographic information acquisition worker, during adjustment, firstly rotating the positioning screw (204) to enable the lower support rod (202) to slide in the sleeve (203), so that the overall height of the upper support rod (201), the lower support rod (202) and the sleeve (203) can be adjusted, and then reversely rotating the positioning screw (204) to fix the whole;
s2, aligning the connecting groove (15) at the bottom end of the mounting seat (3) with the top plate (14), and slightly pressing the acquisition device body (4) downwards to enable the top plate (14) to extrude the limiting block (18), wherein the limiting block (18) pushes the sliding block (17) to slide in the sliding groove (16), meanwhile, the sliding block (17) extrudes the limiting spring (19), when the top plate (14) moves to the position above the limiting block (18), the limiting spring (19) reversely pushes the sliding block (17) and the limiting block (18), so that the limiting block (18) is tightly attached to the lower surface of the top plate (14), and the acquisition device body (4) and the base (1) can be mounted and connected by limiting the top plate (14);
s3, fine adjustment is carried out on the triangular support (2) in the mode of the operation step S1, so that the leveling bubble (7) is in a centered state, and then the geographic information is collected through the collecting device body (4);
s4, after the geographic information is collected, the collecting device body (4) is pressed downwards gently, so that the connecting block (10) props against the whole of the first movable block (11) and the second movable block (12), at the moment, the second movable block (12) can push the limiting block (18), so that the sliding block (17) is pushed to slide in the sliding groove (16) again, meanwhile, the sliding block (17) extrudes the limiting spring (19), when the whole of the first movable block (11) and the second movable block (12) moves to the position above the limiting block (18), the limiting spring (19) reversely pushes the sliding block (17) and the limiting block (18), then the collecting device body (4) is lifted upwards, at the moment, the top plate (14) limits the whole of the first movable block (11) and the second movable block (12), and the first movable block (11) can push the limiting block (18), because the height of the second movable block (12) is smaller than the height of the side wall, close to the limiting block (18), on one side of the connecting groove (15), therefore, the edges of the first movable block (11), the second movable block (12) and the top plate (14) can abut against the side wall of the limiting block (18) close to one side of the connecting groove (15), and then the top plate (14) can be rapidly pulled out from the inside of the connecting groove (15), so that the disassembly operation of the collecting device body (4) and the base (1) is completed.
