Leveling evaluation optimization method and system for engineering surveying and mapping device

The invention provides a leveling evaluation optimization method and system of an engineering surveying and mapping device, which are applied to the technical field of data processing, and the method comprises the following steps: a leveling platform is connected with supporting legs through hinge points, and any one of the hinge points is taken as a coordinate origin; and constructing a first horizontal coordinate axis according to the first adjacent hinge point of the coordinate origin, constructing a second horizontal coordinate axis according to the second adjacent hinge point of the coordinate origin, and constructing a third vertical coordinate axis according to the coordinate origin to generate a space coordinate system. And obtaining platform plane position information, inputting the platform plane position information into a space coordinate system, generating a first horizontal coordinate axis deviation angle parameter and a second horizontal coordinate axis deviation angle parameter, inputting the
