What is 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.
What can we offer?
- Qualified and experienced design engineers, with a combined experience across multiple sectors of over 35 years.
- When comparing the measured 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
6 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 …)
What can photogrammetry be used for?
- 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
