Hand-Held Measurement Device for Capturing the Visual Impression of A Measurement Object |
摘要 |
A hand-held measurement device for appearance analyses includes a measurement array which comprises a number of illumination means for applying illumination light to a measurement field in at least three illumination directions and a number of pick-up means for capturing the measurement light in at least one observation direction. The illumination directions and the observation directions lie in a common system plane. At least one pick-up means is embodied to spectrally gauge the measurement light in a locally integral way, and at least one imaging pick-up means is embodied to gauge the measurement light in terms of colour in a locally resolved way. The spectral pick-up means and the locally resolving pick-up means are arranged such that they receive the measurement light reflected by the measurement field under the same observation conditions and in particular from the same observation direction. |

1. A hand-held measurement device for capturing the visual impression of a measurement object, comprising a housing (H), wherein said housing (H) accommodates a measurement array (MA) and an electronic controller (C) and comprises a measurement opening (6) through which a measurement field (MF) on a surface of a measurement object (MO) is illuminated and the measurement light reflected by the measurement field (MF) is picked up, wherein the measurement array (MA) comprises a number of illumination means (21-27) for applying illumination light to the measurement field (MF) in at least three illumination directions in relation to a device normal (DN) and a number of pick-up means (31-33) for capturing the measurement light in at least one observation direction in relation to the device normal (DN), wherein at least one spectral pick-up means (32) is embodied to spectrally gauge the measurement light reflected by the measurement field in a locally integral way, and at least one imaging pick-up means (33) is embodied to gauge the measurement light in a locally resolved way, wherein that the imaging pick-up means (33) is also embodied to gauge the measurement light in terms of colour, and in that the spectral pick-up means (32) and the imaging pick-up means (33) are arranged such that they receive the measurement light reflected by the measurement field (MF) under the same observation conditions and in particular from the same observation direction.
