Nowadays color phase-shifting technique has been widely used in three-dimensional shape measurement. However, experimental results show that the measurement accuracy of this technique is influenced a lot by the object';s color texture and this technique is suitable for the measurement of objects with neutral color, largely due to the coupling and imbalance of color channels. A new color calibration method is proposed in this article. Through color calibration for the measurement system and approximately obtaining of the object';s color information, the measurement error due to the color texture of the tested object decreases. The measurement result proves its feasibility.
