Reconstruction Algorithm Description

Reconstruction algorithm parameters are filled in the parameter_ field of the POST /openapi/v0.1/open_model/models/reconstruction/start interface; the json object needs to be serialized into a string first. The predefine_AOI parameter at the same level as the parameter_ parameter is an optional parameter and only takes effect in 2D, 3D, and 3DGS jobs. The export_parameter parameter at the same level as the parameter parameter is an optional parameter, setting the directory structure and content of the exported reconstruction results.
