| abstract |
The invention relates to a process and a device for determining the properties of reflective and especially heterogeneous reflective bodies having at least one illuminating means which emits light onto a measurement surface, at least one detecting means for recording the light reflected from said measurement surface, wherein said detecting means comprises a plurality of light-sensitive sensor means and whereby a measurement value may issue from substantially each of said sensor means which is characteristic of the light received by each respective sensor means. A first predefined threshold is provided in a memory means. A controlling means serves to control the measurement sequence and comprises a processing means. Said controlling means directs the measurement sequence such that a measurement value of a sensor means is allotted to a first surface type when same exceeds said first threshold. Said controlling means is such configured so as to allow for the determining of at least one statistical parameter which characterizes said first surface type. |
