Abstract

A new kind of underwater imaging system is introduced, called double-channel imaging system, to both improve the detection distance and solve the problem of inherent delay. A image processing subsystem built on TMS320DM642 DSP is in charge of the two channel videos. And software algorithm is used to degrade the noise and improve the contrast of the videos before they are displayed on the monitor. The trails show that images can be acquired at long distance and very close distance. The quality of the images are greatly improved through the image processing subsystem.
