when B1 < B, the leveling module determines that the first motor and the second motor are running and the first lead screw and the second lead screw move downward.
8. The fixed-point mapping apparatus for engineering mapping according to claim 7, wherein the horizontal adjustment module calculates a second direction adjustment balance screw moving distance LB according to the absolute difference Δ B between the second direction horizontal angle B1 and the second direction standard horizontal angle B, where LB is L2 ÷ tan Δ B, and L2 is a second direction adjustment balance screw moving distance calculation parameter.
9.

when Lm is less than or equal to Ly, the horizontal adjusting module controls the motors to operate until the calculated downward adjustment distance of each lead screw is reached;
when Lm is larger than Ly, the horizontal adjusting module judges that the surveying and mapping device cannot reach the angle required by balance through adjusting the screw rod, and the lifting rod is adjusted again.
10. The fixed-point mapping apparatus for engineering mapping according to claim 9, wherein when the horizontal adjustment module determines not to adjust the balance in the first direction and adjusts the balance in the second direction, Lm ═ LB;
when the horizontal adjusting module judges that the balance in the second direction is not adjusted and the balance in the first direction is adjusted, Lm is LA;
when the horizontal adjustment module determines to adjust the balance in the second direction while adjusting the balance in the first direction, Lm + LB.
