Ship wake image detection system based on laser active illumination
By detecting the laser backscattering characteristics of the ship's wake which are different from the environ-ment,the ship's course,speed,tonnage and other key information can be counter-performed,which has a high military value.In this paper,a set of ship wake imaging detection system is constructed on top of the laser active illumination detection mode combining an industrial camera and a high-frequency laser,which achieves the effective detection of ship wake bubbles with a large field of view and a large dynamic range.Monte Carlo method is used to construct the simulation platform of ship wake imaging detection,and the feasibility of this method is verified.In addition,a proto-type of ship wake image detection system based on laser active illumination is built,and a large number of experiments are carried out under the conditions of indoor laboratory pool to verify the system performance,and the influence of dif-ferent system parameters on the detection performance is analyzed.At the same time,the evaluation of detection per-formance under visible light interference is carried out,which verifies that the system has strong anti-visible light inter-ference ability,and provides theoretical support for the practice of laser active illumination imaging detection mode in ship wake detection.
