Rhopoint TAMS™ Total Appearance Measurement System Next Generation Paint Quality Instrument: Setting New Standards in Appearance Measurement In cooperation with Volkswagen AG & AUDI AG

Open the catalog to page 1

Measurements that closely correlate to human perception are easier to understand and communicate. For maximum impact, an automotive paint finish must instantly produce an appealing visual sensation for the customer. This can only be achieved if the overall surface finish displays both high QUALITY and HARMONY. Rhopoint TAMS is a new way of quantifying appearance quality inspired by a four-year collaboration between Rhopoint, Volkswagen AG and AUDI AG. This innovative new technology models the human perception of surface appearance quality, providing new parameters that revolutionise the...

PERCEPTION Data from the Rhopoint TAMS vision system is processed using perception algorithms derived from extensive human perception studies. CONTRAST Contrast is related to the color of the surface; white and metallic surfaces have low contrast, a deep black measures 100%. Contrast quantifies the visual impact of orange peel and haze effects both being more visible on high contrast dark colors. Reflection in a White surface Reflection in a Black surface SHARPNESS Sharpness quantifies the accuracy of images reflected in the surface, 100% indicates a perfect reflection. At close distances...

WAVINESS Correlated to human perception, waviness quantifies the visible impact of surface waves to an observer at showroom distance (1.5m). The waviness of a surface is critical for determining appearance quality. Low waviness surfaces tend to be preferred by the viewer. Flat surface: Wavy surface: Small structure dominant surface: DIMENSION Indicates the dominant structure size perceived at showroom viewing distance. Typical values are between 1 – 6mm, the dominant structure size is important in determining the harmony between adjacent panels/parts. D= 1.2mm Large structure dominant...

To achieve close correlation with human perception Rhopoint TAMS emulates the human evaluation of a reflective surface, changing its imaging system focus from surface to reflected image. The image transfer qualities of the surface are Waviness is calculated by quantifying Surface topography is analysed to identify the measured and used to calculate sharpness distortion in a reflected image. Dominant structure. APPLICATION OPTIONS Rhopoint TAMS is able to capture surface data for mid gloss and high gloss surfaces offering the possibility of measuring all surfaces throughout the automotive...
