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;用红一绿滤色眼镜观看,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。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.
