| 摘 要： | 提出了一种适用于运载火箭图像测量的简单而有效的图像增强算法。经对大量弱光强运载火箭的图像分析,提出了基于像素通道的图像弱光强背景模型,通过全局最优化求解稀疏矩阵将弱光强图像背景从图像中分离,得到合适的可观测图像,为后续图像数据的处理和识别提供了高质量的信息。

| Abstract: | Image measuring technology is an important component of rocket telemetering. A very simple and effective image enhancement algorithm is proposed in rocket image measuring. Many images which are lack of lightness are analyzed, the algorithm based on weak lightness pixel model is proposed. The global optimal algorithm is used for separate the weak lightness model by solving a liner sparse matrix. The fine image by this method can getted, which is used for the pattern recognition and processing. |
