| Non Contact Measurement |
Dimensional Measurement, Inc.(DMI) offers a variety of vision inspection and non contact inspection services, which are useful in measuring free-form parts and become necessary when measuring flexible or fragile parts. Depending upon the part submitted and the customer’s required output, we can utilize the service that best suits the job – or combine our capabilities to produce the desired final product.
These services include:
These services include:
- ► 3D Laser Scanning
► White Light Scanning
► Reverse Engineering Services
► Camera-based Vision Inspection
Non Contact Inspection:
3D Laser Scanning or Laser Digitizing utilizes a beam of laser light to capture the physical shape of the subject
part, and produces a digital image, or point cloud. Laser digitizing is among the most versatile non contact
inspection services because it is highly portable, suitable for a wide range of part sizes, and capable of obtaining a
large amount of data. Laser Scanning can also be used in tandem with DMI’s contact CMM measurement methods to create reverse engineering solutions that neither measurement method can provide on its own. DMI’s 3D laser
scanning services can be performed either at our facility in Wixom, Michigan, or our metrologists can come to your facility, which is exceptionally helpful for large or sensitive parts.

Another non contact inspection technology available at DMI is White Light Scanning or White Light Digitizing. This system attains point cloud
data by projecting a fringe pattern of light onto the scan area while simultaneously recording the pattern via mounted cameras. This process
allows very rapid digitization of objects, and multiple scans can ultimately be combined to make a whole model. This process is best used on
objects whose features can easily be viewed. White light scanning represents the fastest and most efficient method to digitize larger objects,
such as an entire car body.

The 3D Laser scanning process can provide either 3D or 2D (cross section) results to compare existing
parts to their CAD models. A 3D comparison provides a color map of the CAD model displaying
deviations between the 3D model and the physical part. A 2D comparison provides a whisker plot and
deviations shown by both color and length of the whisker. Both provide a very complete picture of the
part’s condition.

Another important non contact inspection method is camera-based vision inspection, also commonly referred to as video inspection or optical CMM inspection. This method is best suited to thin or soft parts, or to items that cannot be probed easily, such as a very small inspection can be extended to include features that are resistant to other inspection methods by using an impression or casting compound to mold the area, then inspecting the mold of the part.
DMI offers any combination of these inspection methods, which can also be supplemented by our Contact Measurement capabilities.
