Keel installation method assisted by total station instrument and three-dimensional laser scanner

The invention discloses a keel mounting method assisted by a total station instrument and a three-dimensional laser scanner. The method comprises the following steps of (a) performing surveying and setting out by using the total station instrument and determining keel mounting positions, (b) checking an inner molded surface of concrete and preprocessing a concrete surface of a mounting area, (c) preliminarily positioning single keels through the total station instrument and fixing the single keels to annular foundation embedded parts in a spot welding mode, (d) scanning an inner molded surfaceof a layer of keel group by using a three-dimensional laser scanner after each layer of keels is installed and obtaining an installation error of each single keel through post-processing software, (e) carrying out secondary adjustment on the single keels by utilizing the total station instrument according to specific deviation parts and error values, and (f) obtaining an inner profile error of the whole keel group by usi
