Photogrammetry is one of the measurement methods that combines various procedures and techniques. The result is the determination of an object’s three-dimensional form. Using special measurement cameras, it is possible to quickly capture a large number of measurement points. In this field, sigma3D relies, among others, on its partner AICON 3D Systems.
Definition and Workflow:
Photogrammetry is a surveying technique in which an object is measured using a large number of 2D images. The 3D coordinates can be determined for any point that is visible in multiple images taken from different viewing angles.
The prerequisite for calculating 3D coordinates is:
The coordinates of the measurement points are then transferred from the AICON software to graphics software for graphical verification and point assignment.
Measurement volume:
The measurement volume is scalable depending on the application. It ranges from automotive components, such as a door, to large objects used in wind power, such as rotor blades.
Measurement accuracy:
In photogrammetry, measurement accuracy depends on several factors. The distribution of measurement points, the number and position of measurement images, and environmental parameters all play a major role. Depending on the application, accuracies ranging from 10 µm/m to 20 µm/m can be achieved.
Software:
In the field of photogrammetry, sigma3D relies on AICON’s 3D Studio software. Among other things, this software allows measurement images to be transferred directly online to a PC and analyzed. The analysis ranges from simple point determination to a complete deformation analysis spanning multiple measurement periods.
Data Exchange:
Data can be exchanged via email, FTP server, or in person on-site. Alternatively, data can of course also be sent by mail on a CD.
