The XTOP3D XTDP 3D optical photogrammetry system, based on industrial close-range photogrammetry technology, uses internal and external camera parameter calibration and pattern recognition technology to track image feature points, enabling full-field displacement measurement of structures. This computer vision-based, non-contact displacement measurement solves the challenges of multi-point displacement and limited range testing. It also offers simple installation, high test frequency, and minimal interference with the measured object caused by contact.

Similarity simulation experiments are one of the primary methods for studying indoor mining models. Traditional observation methods rely primarily on physical or mechanical measurements, which suffer from drawbacks such as cumbersome installation of observation devices or sensors, high workload, and limited sampling points. The XTDP 3D optical photogrammetry system, incorporated into similarity model observations, provides a convenient measurement method for similarity model experiments in mining.

The XTOP3D XTDP 3D optical photogrammetry system, based on the principles of close-range industrial photogrammetry, takes multi-angle photos of cylindrical parts with markers attached to their surfaces. It can calculate the 3D coordinates and displacements of the markers before and after welding, and analyze the full-field 3D static deformation of cylindrical parts during welding.

The use of 3D photogrammetry technology + high-precision 3D scanners can effectively help hydropower equipment service providers complete 3D inspection of large turbines, detect dimensional deviations of blades, ensure that blades meet production and assembly standards, significantly improve the efficiency and accuracy of quality control of large-scale hydropower equipment, and greatly enhance the production efficiency of the energy equipment industry.

XTDP 3D optical photogrammetry + XTOM high-precision 3D scanner is used to measure large forgings and castings, determine machining allowances and partial machining dimensions, perform full-size measurements of products, and ensure comprehensive product quality.

Given the massive dimensions of the subway car body, the scanning process employed a measurement strategy combining an XTOM blue-light 3D scanner with global photogrammetry. Global photogrammetry was first used to capture spatial reference points on the car body, followed by the use of the XTOM blue-light 3D scanner to acquire 3D data for areas with complex contours, ultimately generating a complete 3D data model of the car body.
