【摘要】：在环境比较恶劣下条件下,激光主动成像系统的图像质量严重下降,为了获得更加理想的图像视觉效果,提出一种激光主动成像系统的图像质量改善方法。首先采用小波变换的多尺度分析功能对原始激光主动成像系统产生图像进行去噪处理,消除噪声去图像视觉效果的干扰,然后采用基于色彩恒常理论的Retinex算对图像进行增强处理,使图像更加符合人眼视觉特性,丰富图像的色彩信息,并采用双边滤波算法改善图像对比度,提高图像的动态范围,然后采用图像质量评价的主观和客观标准对图像质量改善效果进行分析。结果表明,本文方法明显改善激光主动成像系统的图像质量,可以满足激光主动成像系统的实时处理需求,具有良好的视觉欣赏效果。
[Abstract]:The image quality of laser active imaging system is seriously reduced under the condition of bad environment. In order to obtain more ideal image visual effect, a method for improving the image quality of laser active imaging system is proposed.Firstly, the image generated by the original laser active imaging system is de-noised by using the multi-scale analysis function of wavelet transform, which eliminates the interference of the visual effect of noise de-image.Then the Retinex algorithm based on the color constant theory is used to enhance the image, which makes the image more accord with the human visual characteristics, enriches the color information of the image, and adopts the bilateral filtering algorithm to improve the contrast of the image and increase the dynamic range of the image.Then the subjective and objective criteria of image quality evaluation are used to analyze the effect of image quality improvement.The results show that the proposed method can improve the image quality of the laser active imaging system and meet the real-time processing requirements of the laser active imaging system. It has a good visual appreciation effect.
