Product Overview

The 3D Model Reconstruction software produces 3D geometric models of complex test structures from a batch of 2D photos.

EDM Online Visualization window is available in all the test types of the EDM software, including EDM DSA, VCS and EMA. This option provides fast and efficient structural model generation and full 3D visualization of the structure deformation under test.

EDM Modal Operational Deflection Shape (ODS) allows users to better visualize the deformation of the structure under test. Time domain data and spectrum data are animated using the animation feature of the geometry model. This feature is integrated with EDM Modal Geometry and works for all types of EDM Modal testing.

Key Features

3D Model Reconstuction

There are three methods of generating a three-dimensional geometry model of the structure under test.

  • Take photos of model for construction (2D to 3D)
  • Import FEA/CAD model
  • Create model using geometry editor

Crystal Instrument’s 3D Model Reconstruction software uses the advanced technology of 2D to 3D reconstruction to provide a simple solution to the intricacies of creating 3D geometric models of convoluted test structures. This approach not only saves the user time and effort but also provides an accurate model with great simplicity. The user simply takes photos of the test article and feeds it into the software. These images are matched to extract the features and a 3D model of the structure is constructed after point and surface reconstruction processes. This method is extremely easy to use, does not require any manual labor and is much quicker than the other two approaches.

Continuous Data Recording

During vibration control, all measurement input and drive signals can continuously record to a Spider-NAS or the internal storage residing in each front-end. Users can view and analyze data files with Crystal Instruments Post Analyzer. The variable sampling rate can be enabled to simultaneously record slow-change signals together with high speed vibration data.

A Spider system can consist of one or more Spider hardware front-ends. The user constructs the system by combining Spider front-ends detected on the same LAN. The software validates and displays hardware attributes of each Spider front-end. The following hardware is supported by EDM VCS software for vibration control, monitoring, and data acquisition.

  • Spider-81 Premium Vibration Controller
  • Spider-81B Basic Vibration Controller
  • Spider-80X High Channel Vibration Controller – Scale up to 512 Channels
  • Spider-80Xi High Channel Vibration Controller – Compact, handheld high channel system
  • Spider-80M MIMO Vibration Control System
  • Spider-80SG General Data Acquisition Device with Strain Measurement


Monitoring Through EDM Cloud

All tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
