Foundation pit engineering horizontal displacement control adjustment method, storage medium and equipment
The invention discloses a foundation pit engineering horizontal displacement control adjustment method, a storage medium and equipment, and the adjustment method comprises the steps: arranging observation piles at four corners of a foundation pit respectively, erecting a machine vision measuring instrument on each observation pile, and determining the azimuth angle of the machine vision measuring instrument; arranging a fixed point on the extension line of the observation direction of each machine vision measuring instrument, and arranging a plurality of to-be-measured point targets on any edge of the foundation pit; after observation is carried out for a period of time, the observation offset of each observation pile is obtained through a machine vision measuring instrument, and the distance change value between the observation piles is calculated; establishing an adjustment equation according to the observation offset of each observation pile and the distance change value between the observation piles; and establishing a normal equation and a minimum norm condition, solving an adjustment equation, obtaining an optimal estimation result of the displacement parameters of the observation pile, and correcting the optimal estimation result into observation data of the target of the point to be measured. According to the method, a high-precision photogrammetry solution under a complex foundation pit environment is effectively filled.
