摘　　要：提出了一种确定水下光学监控系统中照明光源方向角和安装位置的方法.利用光在水中的传输特性,分析了传输距离、体积散射函数、散射角和小体积元的影响,以及照明光源不同方向角产生的不同照明效果.据此提出了光源方向角的确定原则,即在满足监控区域要求的前提下,照明光源的方向角应该选取散射角最大的方向.在视场角为45°时,光源方向角应为67.5°.根据监控范围边界的要求以及光源方向角,确定光源安装位置.实际应用结果表明,此方法可以很好地满足水下光学监控系统的要求.A method to determine directional angle of light source and installation location was proposed.Using transmission characteristics of underwater rays of light and considering transmission distance,volume scattering function,scattering angle and the small volume unit,the illuminating effect of various directional angle of the light source were analyzed.The selection principle of directional angle of the light source was proposed.It was that when meeting the requirements of the monitoring area,dirctional angle of the light source should be chosen to make the scattering angle maximum.When the view field angle was 45°,directional angle of the light source should be 67.5°.According to the boundary of the monitoring area and directional angle of the light source,the installation location of the light source was determined.The real results show that the system can meet the requirements of monitoring and has good effect.
