Most industrial vision applications use black and white sensors. Specific lighting or optical filters are often used to analyze colored parts. Nevertheless, this approach can be inadequate for applications in particular domains (foods, printing, etc.). In some cases, it can be necessary to analyze the hue of the parts in addition to their intensity. The availability of low- cost CCD color cameras allows the development of this kind of solution. The purpose of the project presented here is to define and develop a color vision system corresponding to industrial requirements, especially in the range of low to medium performance systems. Such a system must respect the following constraints: (1) wide variety of problems and small amount of equipment for one kind of application, (2) cadences: many applications need to control about 10 parts per second, and (3) cost.
