CASE STUDY: Matrix Wand System

"Guidelight’s communication skills and strict adherence to budget and deadlines has allowed Matrix to once again bring to market a cutting-edge product providing infinite measurements to every one of our customers in the collision repair industry."

Objectives



  • Create handheld, automotive measurement tool to supplement current chassis system
  • Design state-of-the-art, precision measurement system that is “massively simple”
  • Provide rich features only achievable through an image-based technology
  • Utilize off-the-shelf components as much as possible

Challenge

Being the first handheld, photographic measurement tool of its kind, it was important to first prove the feasibility of creating a system that was not only accurate and repeatable but also robust enough to survive the body shop environment. Off the shelf components had to be integrated into a stable and reliable product easily operated by non-technical users.

Response

The Guidelight research and development team defined a hardware/software system which integrates multiple technologies including stereo imaging, digital photography and photogrammetry in a unique manner to produce a next generation tool. The Guidelight project management and R&D teams worked with stakeholders and an outside fabrication vendor to ensure prototype functionality through continuous development, testing and refinement.

The software application was created using the C# programming language and the .NET 3.5 libraries. Microsoft technologies include Windows Presentation Foundation (WPF) and the XML Paper Specification (XPS). The OpenCV computer vision library was used for image processing, and the open-source Math.NET scientific computation library was used to perform various calculations.

Due to the optical characteristics of contemporary lenses and imaging systems, Guidelight developed manufacturing and end-user calibration procedures to ensure long-term accuracy of the Matrix Wand. The resultant procedures enable the manufacturer to establish baseline values for the solution. End users periodically supplement these values through a simple and automated procedure that provides the fine tuning necessary to deliver high-quality, repeatable measurements throughout the duty cycle of the product.

Results

Scientific theory transitioned from concept to commercial product. The resulting Matrix Wand System enables any automotive technician to quickly measure the extent of sustained vehicle damage by capturing digital images of suspected areas with a handheld measuring device.
