摘　　要：受限于通信技术和多种客观因素影响,军用微型无人机回传视频效果一般,其清晰度无法令人满意。为提高军用微型无人机回传视频图像质量,采用基于稀疏字典和动态纹理合成的算法处理回传视频图像,实现了军用微型无人机拍摄图像的高清还原。以实际场景采集的图片为样本集进行系统测试,测试结果验证了该算法的有效性。Due to the influence of communication technology and various objective factors, the effect of postback video from the military micro unmanned aerial vehicle(UAV) is ordinary, and its legibility is hardly satisfactory. To improve the quality of the postback video image from the military micro UAV, the algorithm based on sparse dictionary and dynamic texture synthesis is adopted to process the postback video images. Thus, the high-definition restoration of the image from the military micro UAV is realized. With the sample picture set collected in actual scenes, system testing is carried out, and the testing result verifies the effectiveness of the algorithm.
