AC Cobra Photogrammetry

Photogrammetry is a technique of taking measurements from photographs

The output of photogrammetry is a 3D model of a real-world object. A camera is positioned close to the subject and is typically hand-held or on a tripod. The output is 3D models, measurements and point clouds. Everyday cameras are used to model and measure engineering structures.

Optical 3D Coordinate Measuring Machine

The measured and aligned data is used for various tasks:
• CAD comparison
• Verification of shape and position tolerances
• Verification of specifications from drawings, files or tables
• Initial measurements

When comparing the measuring data with CAD data (IGES, VDA, STEP, Catia, ProE, UG …), the corresponding measuring reports are created in the familiar formats:

• False-colour representation
• Deviation of individual points as labels
• Sections, angles and distances
• Diameters and flatness
• Tables and lists

Advantages of the TRITOP Technique

• Complete 3D measuring machine with minimum hardware requirements (2 cases with a total weight of 23 kg)
• The object is not touched during measuring
• Very high accuracy also for large objects
• No wear and tear, no decrease of accuracy
• Easy handling
• Independent of environmental conditions (climatic chamber, open air …)

Photogrammetry: Fields of Application

• Inspection of sheet metal parts and car bodies, e.g. in pilot production, process optimising, tool try-outs, start of series production or during random samples
• Quality control of large objects, e.g. aircraft, ships, wind turbines, etc.
• Verification of plastic parts, e.g. for first article inspection
• Verification and recording of jigs and fixtures
• Measuring of models and prototypes, e.g. vehicle interior and exterior design
• Verification of tubes and wires with respect to their three-dimensional shape
• Measuring trimming edges of two-dimensional sheet metal blanks
• Deformation analysis of car and climatic chamber tests
• Measuring of reference point fields

CT Scanning

The CT scanning process is non-destructive & has the ability to show the inside features and components of a part, allowing key components to be seen in their functioning position and be analysed without disassembly.
