Construction method for accurately calibrating sludge solidification range, depth and volume

The invention discloses a construction method for accurately calibrating the solidification range, depth and volume of sludge. Based on the principle of GPS positioning and image recognition, accurate calibration of the field sludge in-situ curing range is achieved, meanwhile, the amount of a curing agent needed by each block is accurately controlled in combination with control over the amount of the curing agent needed, the problems that curing is repeated and the using amount of the curing agent is uncontrollable in the sludge in-situ curing process are solved, the curing effect of field sludge curing is greatly improved, and the curing efficiency is improved. Meanwhile, intelligent management of the on-site sludge curing range and the curing agent volume is achieved, accurate control over the sludge in-situ curing range and volume is ensured, the problems that in the sludge curing process, curing areas are repeated, the curing areas are omitted and the like, and consequently the bearing capacity strength o
