When measurement is mentioned, most people think of a touch probe, measuring arm or a CMM machine. These technologies are an established standard in industry. Modern automotive development, however, increasingly requires faster, more flexible and non-contact solutions for situations where traditional methods are not practical. One such approach is static photogrammetry \u2013 precise 3D measurement based on a series of photographs and optical markers.<\/span><\/p>\n

How does photogrammetry work?<\/span><\/h2>\n

The principle is simple: a technician places optical markers on the object and then takes a series of images from different angles. Specialised software recognises these markers and calculates their exact 3D coordinates using triangulation. During measurement, the object remains stationary, the images overlap, and the result is a 3D point cloud formed by the positions of the markers. This data can then be compared with a CAD model and used for deformation analysis, simulations or documentation.<\/span><\/p>\n

The benefits? fast, accurate and non-contact<\/span><\/h2>\n

The key advantages of <\/span>photogrammetry<\/b> are <\/span>speed, accuracy and reliability<\/b>. Components are measured without physical contact, <\/span>protecting even sensitive parts from damage or deformation<\/b>. With correct setup, accuracy reaches up to <\/span>one tenth of a millimetre<\/b> \u2013 exactly the level required for automotive development and testing. Another major benefit is visualisation. Colour deviation or deformation maps significantly simplify the presentation of results. And most importantly: technicians can measure virtually anywhere \u2013 <\/span>in the laboratory or directly at the customer\u2019s site.<\/b><\/p>\n

Photogrammetry as a daily standard at AUREL<\/span><\/h2>\n

At AUREL, this method is part of <\/span>everyday practice<\/b>. The team uses it to measure deformations after crash tests, check deviations and complement other measurement methods \u2013 <\/span>point measurement as well as 3D scanning<\/span><\/a>. <\/span>An experienced team<\/b> of specialists, a spacious laboratory, high-quality equipment and up-to-date software ensure that this advanced technology operates reliably and efficiently on a daily basis.<\/span><\/p>\n
