【摘要】 针对实际应用中近距离成像产生的图像照度不均匀现象,从成像的光照模型出发,提出了一种具有自适应性的灰度修正方法,并与已有的灰度修正方法进行了对比分析。实验表明,该方法快速有效,并特别适用于基于高速图像处理的机器视觉系统。更多还原

【Abstract】 Imaging at close distance leads to uneven illumination images in practical application. Based on the illunination model, a new gray-level correction method with adaptability was proposed. Being analysed and compared with existent methods, this new method was proved fast and effective, and suitable to high-speed image process in machine vision systems.更多还原
