激光主动成像系统目标图像质量评价参数研究

图像质量评价是研究激光主动成像探测系统成像性能的重要内容，文中从图像的噪声、灰度和纹理等方面对距离选通激光主动成像目标图像进行了量化评价。通过深入研究主动成像图像的特点，建立了信噪比、亮度、对比度和清晰度等评价函数的参数模型，并给出了实验结果和分析。结果表明，这些参数能够对激光主动成像图像进行客观的评价，并且计算简单，具有显著性和独立性的特点。

Image quality assessment of laser active imaging system

Image quality assessment is essential to the research of imaging performance of laser active imaging system. The quality of laser active illumination image is quantitatively from three aspects of the image, namely noise, gray leveland texture. After deeply study the characteristic of the images, the paper put forward the mathematics models of SNR, brightness, contrast and definition, and the experimental results and analysis are also given. Experimental results show that the quality of images can be evaluated by the parameters objectively, easily and independently.
