| 摘 要： | 为了降低激光灰度图像标记实现复杂度,并获得较快的标记速度和较好的标记质量,采用图像处理中的位平面概念对标记图像进行分层,并用不同的激光能量对图像进行分层标记。通过激光能量的多次叠加得到灰度标记图像。采用该方法在振镜式激光标记机上进行了大量验证实验。结果表明,与传统的激光灰度图像标记方法相比,提出的新方法大大地降低了高质量灰度图像标记的实现难度,同时又保证了标记速度和标记质量。该方法亦可用于彩色图像标记中,对提高激光图像标记水平有重要意义。

| Abstract: | In order to reduce the complexity of laser-induced gray image, and guarantee the marking speed and marking quality, gray image is divided into different layers using bit-plane concept in image processing. Different laser energy is used to mark different layers. The gray image is induced by multiple layer stacking. This new e method is tested and verified on galvanometer-type laser marking machine. Large number of experiments is carried out. Compare of the traditional methods, the result show that the new method greatly reduce the complexity of high quality laser-induced gray image, and guarantee the marking speed and marking quality.Bit-plane method can also be used to laser-induced color image. It is significance to improve the level of laser-induced image with this method. |
