补色法随机点立体防伪商标制作系统研究

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...

The system for generating complementary color random dot stereo anti counterfeiting label

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.
