This paper presents an algorithm of automatic colour chart detection and colour patch value extraction.The algorithm can detect different types of colour charts in various images. The efficiency of algorithm is measured by successful detection of the X-Rite ColorChecker and compared with the performance of the X-Rite ColorChecker Camera Calibration software. The experimental study shows that proposed algorithm successfully found the colour chart in 77.3% of tested images while the X-Rite software in 53.8% of tested images. The experiments specify optimal image acquisition conditions for successful colour chart detection.

W artykule przedstawiono algorytm automatycznej detekcji wzornika barw i ekstrakcji wartości barw jego pól. Algorytm umożliwia wykrycie różnych typów wzorników barw w różnych obrazach. Efektywność poprawnej detekcji badano wykorzystując wzornik ColorChecker firmy X-Rite i porównywano z efektywnością detekcji programu X-Rite ColorChecker Camera Calibration. Badania doświadczalne wykazały, że zaproponowany algorytm poprawnie wykrywał wzornik barw w 77,3% badanych przypadków, podczas gdy oprogramowanie firmy X-Rite w 53,8% badanych obrazów. Eksperymenty pozwoliły określić optymalne warunki akwizycji obrazu dla pomyślnej detekcji wzornika barw.
