The invention relates to the technical field of scanning measurement, in particular to a large assembly type prefabricated part size detection three-dimensional scanning site layout method, which comprises the following steps of: identifying geometric elements on an end face based on a part design drawing and combining functions, and sorting key sizes; dividing a key size based on the allowable deviation and a field quality acceptance standard, and judging whether a key size area is a key observation end face area or not; based on the recommended working distance and the incident angle range of the three-dimensional laser scanner, two scanning sites are preliminarily arranged on each end face; in the length direction of the component, one or more scanning units are used for station distribution; according to the method, target balls are arranged and data are collected under typical distances, spherical surface fitting is carried out on target ball point clouds under each typical distance, the rule that the diameter fitting deviation of the target balls changes along with the scanning distance is obtained, and on the premise that the critical dimension error meets the engineering requirement, the number of stations is reduced, and the working efficiency is improved. And the field scanning efficiency and the objectivity and repeatability of a size detection result are improved.

This application provides a method, apparatus, equipment, and storage medium for efficient on-site quality control of node data. The method includes: selecting target node synthetic seismic data for a target work area; performing maximum amplitude limitation processing on the target node synthetic seismic data to obtain node synthetic seismic data to be processed, wherein the recording length of the target node synthetic seismic data is within a preset time period and the number of traces is within a preset range; for each shot's node synthetic seismic data to be processed, determining whether the current shot's synthetic seismic data is an empty file based on the amplitude of the sampling points in each trace of the current shot's synthetic seismic data, and removing the empty files; for the synthetic seismic data after removing the empty files, statistically analyzing the synthetic quality and the working status of nodes in multiple domains based on the non-working trace head attributes and the multi-domain overlay profile trace head attributes, and performing high-quality node data synthesis checks and node status quality control for massive 3D node data.
