To meet the needs of training leading talents of science and technology for the future development olthe ocean, an underwater laser imaging experiment was designed and applied to the university physicsexperiment course. The experiment combines optical, mechancal, electrical, algorithm, control, ete. Theunderwater laser imaging system is built by using laser, industrial camera, displacement device, etc. Theexperimental processing software is written by C++, and the 3d morphology measurement of underwater target isrealized through the extraction method of laser fringe center,The application of the system to experimental teaching is helpful for students to master the relevant knowledge of underwater laser imaging technology, and improve students’ innovation consciousness and engineering application ability.
