Algorithm parameter introduction

Reconstruction Algorithm Description#

The reconstruction algorithm parameters are filled in the parameter_ field of the POST /openapi/v0.1/open_model/models/reconstruction/start API. The JSON object needs to be serialized to a string first. The predefine_AOI parameter, at the same level as parameter_, is an optional parameter and only takes effect in 2D, 3D, and 3DGS jobs. The export_parameter parameter, also at the same level as parameter, is an optional parameter that sets the directory structure and content of the exported reconstruction output.
{"resourceUuid": "{your resource uuid}", "parameter_2d": "{\"parameter\": {}, \"predefine_AOI\": {}, \"export_parameter\": {}}"}
