Non-contact 3D measurement

We are experts for contactless wheel alignment: We have been manufacturing and selling our 3D measurement probes worldwide for over 15 years. Our probes work on the principle of stereophotogrammetry, i. e. 2 synchronously operating
cameras record images of the illuminated tire and use them to generate a 3D model from which all relevant chassis parameters such as toe and camber can be determined reliably and quickly. The probes are connected to a measuring computer via GBit Ethernet.

The different models have particular strengths in different applications, so we can offer the perfect solution for every system. For data evaluation in a wheel aligner, we recommend our VisiWheAl measurement software for all sensor types.

Overview over our measurement probes

VisiCon VisiScan
The Innovative

The VisiScan is the newest generation of our 3D measurement probes. By means of 4 centrally positioned laser scanner units, only the relevant areas of the measurement object are illuminated dynamically. Thus, a larger number of relevant measurement points are identified for each measurement and an improved signal-to-noise ratio is achieved. On one hand, this significantly
increases the quality of the measurement data while at the same time achieving complete independence of the measurement of the rims (e. g. highly reflective). In addition, impairment of the worker in the pit due to stray light is completely avoided.

Benefits at glance:

dynamic illumination of only relevant areas of the measured object
totally independent of the type of rim
large measurement range for a broad vehicle mix
protection of the worker against stray light
insensitive to ambient light
reliable measurement technology and software

VisiCon dPP
The Classic

The VisiCon dPP probe (dynamic Pattern Projection) is a measurement sensor for non-contact three-dimensional detection of surfaces. As standard, eight laser blocks (2 x 32 laser lines) are used for dynamic illumination of the measurement object. For larger tires or other types of vehicles (e. g. trucks), variants with 10 and 12 laser blocks are also available (2 x 40 or 2 x 48 laser lines). Due to the proven differential imaging method, the probe achieves a high level of independence from extraneous light. In addition to the standard metrics, an optional illumination unit simultaneously measures the height of the wheel house edge.

Benefits at glance:

one probe per tire
quickly ready to measure
large measurement range for a broad vehicle mix
different versions available depending on
the type of vehicle (dPP32, dPP40, dPP48)
insensitive to ambient light
reliable measurement technology and software

VisiCon dPP Twin
The Flexible

The dPP Twin is a variant of our trusted dPP probe, specifically designed for integration in test benches with confined space conditions and small measurement distances. It is suited to update existing wheel aligners that are equipped with technically outdated 2D measurement technology (e. g. Perceptron). For dynamic illumination of the measurement object, three laser blocks (24 laser lines) are used as standard in each of the two measuring heads. The distance between the measurement heads is variable and thus enables the measurement of a broad range of tires.

Benefits at glance:

small measurement distance (min. 420 mm, max. 620 mm)
flexible positioning of the measuring heads in relation to each other depending on the
type of vehicle (suitable for cars and trucks)
quickly ready to measure
insensitive to ambient light
reliable measurement technology and software
