摘要

摘要: 根据光线传输理论，推导照明光源角度配置对水下成像图像质量的影响。在光源和摄像机与目标距离相同的条件下，通过对图像衬度与信噪比传递函数的推导，得到了在成像距离不变条件下图像的衬度和信噪比随光源角度变大而增大的规律，并绘制出衬度和信噪比随光源角度变化的曲线，还对推导过程中引入的主要假设和近似条件对结果精确的影响进行了分析。最后对光源角度配置对图像质量的影响进行了有关验证实验，实验结果与理论结果一致。

Abstract: We present our research about the imaging quality of underwater imaging systems based on the angle configuration of the light source. Supposing the distance between the light source and the target is equal to that between the camera and the target, we developed better transfer functions of the contrast degree and the signal-to-noise ratio (SNR). By defining that the distance from camera to the target is invariable, we described the dependence of the contrast and SNR on the angle configuration of the light source, we also gave some curves of this relationship. We analyzed the impact on the imaging quality caused by the hypothesis and the approximate. Experimental results agree with our analysis.
