Title: Measuring system for the accurate determination of the colour of an object by means of a colour camera without fetching superfluous information
IPC: G01J3/50
Filed: 1993-10-13
Abstract: The invention relates to a measuring system which allows a low-cost, industrial, RGB colours, matrix camera to be used to separately determine the colours "red", "green" and "blue" of each image point (pixel) located within the field of vision of that camera. A software program allows the image-line number and pixel number to be stated in a simple manner, the measuring system returning the values of these three colours. This is possible with each successive image, the position of the pixel to be measured being allowed to vary all the time. The measuring system is suitable, in particular, for those cases where the colour has to be measured of objects which are relatively small with respect to the entire video image. The advantage of this measuring system compared with existing measuring systems (so-called frame grabbers) is its simplicity, resulting in a low cost price. The measuring system further allows the colour to be measured with high accuracy and is particularly fast, so that measurements can be carried out on successive frames. The measuring system moreover requires virtually no computer time from the computer system of which it forms part.
