With the fast development of embedded technology, the Fiber Bragg Grating (FBG) image demodulate system designed through the embedded microprocessor make it possible to implement real-time and fast processing of a large number of sensory data. Analyzing the characteristics of FBG image captured by the embedded Fiber Bragg Grating (FBG) image demodulate system,this article presents a second-denoising algorithm unified neighborhood average and distance transform in spatial domain. The experimental results show that using this second-denoising algorithm inheriting the advantages of neighborhood average and distance transform in image denoising, error of location between light spots would be less than 0.2 pixels, and the demodulate results are satisfactory in the embedded Fiber Bragg Grating image demodulate system.
