| 中文摘要: |
| 为了满足日益增长的商品防伪需求,研究设计了一种补色法随机点立体防伪商标制作系统。将CCD拍摄的实际商标图像输入计算机,通过VC++编程提取商标像素点的灰度值作为横向视差值(对应于深度值);由此产生一幅滤去蓝绿色的红色随机点背景图(左眼图)和另一幅包含商标深度信息的绿色随机点图(右眼图);最后将两幅随机点图叠加,制作出一张补色随机点立体商标图;用红—绿滤色眼镜观看,即可观察到逼真的商标立体效果。采用这一方法及系统,设计制作了多种随机点立体防伪商标图案,得到满意的实验结果,为实际应用提供了技术基础。 |
| 英文摘要: |
| To satisfy the increasing demands of anti conterfeiting for commercial products, a novel designing and generating system for complementary color stereo anti counterfeiting labels is proposed. The image of real label is captured by a CCD and imported to the computer. The grey scales of pixels in label image are picked up and converted into binocular disparity(corresponding to depth)using Visual C++ programming. A blue green filtered image(left image)serving as red background and a red blue filtered image(right image)containing the label information are then generated. The two images are finally overlaid into one complementary color stereo anti counterfeiting label, which can be observed using a pair of red green glasses. With this method, we designed and made some typical anti counterfeiting labels, showing satisfactory and vivid label effect. The system and software provide technical foundation for practical applications. |
