Design of specific period clear imaging system for swing propeller target image

针对传统船舶摆动螺旋桨目标周期图像成像系统,在特定周期下受到外界环境光影响,无法在微光环境中摆动螺旋桨目标清晰成像的问题,进行深度分析。根据分析结果提出设计摆动螺旋桨目标图像特定周期清晰成像系统。首先对传统系统硬件部分进行修正,修正方式采用创建新硬件的方式。通过创建微光COMS图像采集单元,对传统硬件图像采集环境参数进行提升修正;其次,引入图像噪声概率算法对采集图像进行噪声参数优化,得到清晰摆动螺旋桨目标特征周期图像。最后,通过对比实验的结果数据证明提出设计的系统能够解决传统系统特定周期摆动螺旋桨目标成像清晰度差的问题。

Aiming at the problem that the periodic image imaging system of the traditional ship swing propeller target is affected by the external environment light in a specific period and can not image the swing propeller target clearly in the lowlight environment,depth analysis is carried out.According to the analysis results,a specific period clear imaging system for the target image of oscillating propeller is designed.Firstly,the hardware part of the traditional system is amended by creating new hardware.By creating a low-light-level COMS image acquisition unit,the traditional hardware image acquisition environment parameters are upgraded and corrected.Secondly,the image noise probability algorithm is introduced to optimize the noise parameters of the acquisition image,and the clear characteristic periodic image of the swing propeller target is obtained.Finally,by comparing the experimental results,it is proved that the proposed system can solve the problem of poor imaging clarity of the traditional system with oscillating propeller in a specific period.
