Abstract
Embedded steel billet character is low contrast. The uneven illumination distribution and oxidation would affect embedded character detection in images correctly. A novel method based on structured light for embedded character acquisition and extraction is proposed. First the embedded character is irradiated by structured light, embedded character would bend the structured light. The processing algorithm based on Fourier transform, picks up the carrier wave from the reflected image. The reflected image is demodulated and filtered to extract the embedded character. Experimental results show that the algorithm is conciseness and effective. The algorithm has the integrity, is not easy to be interfered by noise. The proposed method has reliability and application.
