符合激光雕刻特点的图像处理方法

Image processing method to fit on laser-carving characteristics

随着激光和计算机技术的迅猛发展,激光雕刻技术在加工领域得到了广泛应用。目前常用的激光雕刻系统大多是用来雕刻图形或是二值图像,具有一定的局限性。对基于灰度图像雕刻的激光雕刻控制系统进行了研究,针对具有256个灰度级别的BMP格式的灰度图像,着重介绍了一种适合于激光雕刻特点的数字图像处理方法——直方图均衡化法,处理后的图像再经过灰度转换,生成一幅较好的激光雕刻图像,使雕刻的图像具有一定的灰度层次,更加逼近真实图像。

With the rapid development of the laser and computer technique, Laser-carving technique in processing field has got more extensive application. Now most of the laser-carving system are only applied for carving graphics or binary images, and they have some limitation. This work studied the laser-carving control system on the base of carving gray degree images. A kind of the digital image processing method, which is fit on the laser-carving characteristics, is introduced mainly. This method is called Histogram Equalizing. After processing, the gray degrees conversion still need to be done. At last, a very good laser-carving image is generated from the image which has 256 gray degrees with the format of BMP, by which the carved images will have more gray degrees. And they can match with the original images better.
