Digital Photogrammetry System for Accurate and Rapid 3D Coordinate Measuring and Deformation Analysis
TRITOP is a portable hand-held digital photogrammetry system that performs fast and accurate 3D coordinate measurements as well as deformation analysis. Measuring tasks that traditionally were performed by tactile 3D coordinate measuring machines can now easily be carried out with the TRITOP system. It does not require any complex, heavy and maintenance-intensive hardware. The measuring machine comes to the object. TRITOP can be used as a standalone photogrammetry system for inspection and deformation analysis, or it can be used in conjunction with ATOS to help maintain accuracy over very large areas.
Hand-held Wireless Photogrammetry System
TRITOP measures coordinates of three-dimensional objects quickly and precisely. Measuring tasks that traditionally were performed by tactile 3D coordinate measuring machines can now easily be carried out with the TRITOP system. It does not require any complex, heavy and maintenance-intensive hardware. The measuring machine comes to the object. As with tactile coordinate measuring machines, TRITOP records the coordinates and their orientation in space for any feature of interest:
Surface points and sections
Primitives
Holes, punch holes and edges
Diameters, lengths, angles, etc.
After the 3D coordinates have been determined, the measurement mathematically is transformed into the coordinate system of the component- RPS, Gage alignment, Best-fit, etc.
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 etc.), the corresponding measuring reports are created in the familiar formats:
False-color 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 etc.)
Static Deformation Analysis
TRITOP is an optical, mobile, measurement system, which accurately defines the 3D coordinates of object points at quasi-static conditions. Based on this information TRITOP is capable of calculating 3D displacements and deformations of objects and components. It replaces conventional displacement measuring systems or LVDTs capturing displacements and deformations rapidly without cables or sensors on or around the object, and does therefore not interfere with the object.
Fields of Application
Inspection of sheet metal parts and car bodies, e.g. in pilot production, process optimizing, 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
Technical Data
Using TRITOP, objects of up to 20 m can be measured. Depending on the measuring task, different camera systems are available. All TRITOP systems are self-calibrating and self-checking.
