为提升低质量舰船航行图像质量，为舰船航行监测提供可靠依据，设计基于视觉感知技术的低质量舰船航行图像增强系统。该系统以同步动态随机存取内存中存储的低质量舰船航行图像为基础，利用FPGA矫正图像畸变后，在SDRAM控制模块的控制下，经由通信模块将图像传送至图像增强模块中，该模块采用视觉感知技术，增强舰船航行图像后，通过PCI总线传送至PC机中，呈现低质量舰船航行图像增强结果。测试结果表明：该系统具有较好的低质量图像增强性能，增强后图像的度平均梯度和图像信息熵的结果均在0.92以上；图像的边缘轮廓质量较好，有效改善了图像模糊情况，并且避免图像增强后发生色彩失真现象，图像细节的完整性较好。
In order to improve the quality of low-quality ship navigation images and provide reliable basis for ship navigation monitoring, a low-quality ship navigation image enhancement system based on visual perception technology is designed. The system is based on low-quality ship navigation images stored in synchronous dynamic random access memory. After correcting image distortion using FPGA, the image is transmitted to the image enhancement module through the communication module under the control of the SDRAM control module. The module uses visual perception technology to enhance the ship navigation images, which are then transmitted to a PC through PCI bus, presenting the results of low-quality ship navigation image enhancement. The test results show that the system has good low-quality image enhancement performance, and the results of the degree average gradient and image information entropy of the enhanced image are both above 0.92. The edge contour quality of the image is good, effectively improving the image blurring situation; And to avoid color distortion after image enhancement, the integrity of image details is good.
