Xingyu Zhou, Peng Cao, Xia Zhang . Design of Multi-spectral Anti-counterfeit Image Acquisition and Detection System. International Journal of Computer Applications. 186, 2 ( Jan 2024), 25-32. DOI=10.5120/ijca2024923348
Multi-Spectral Images (MSI) technology has received widespread attention in recent years in the field of printing information anti-counterfeiting because of its significant advantages in information hiding, anti-copying, etc. The development of MSI technology is affected by multiple factors such as light source, camera, hardware, and software systems and algorithms, and is subject to mutual constraints, which puts high demands on the hardware, software, and optical system design. In this paper, we design an MSI acquisition and detection system with a spectral range from 265nm to 1700nm, covering the full spectral range of ultraviolet light, visible light, and near-infrared light, and give the hardware and software system framework of the detection system. In terms of hardware design, the cooperative control of peripherals and multispectral light sources is realized by using an ARM architecture chip as the control unit. For software design, the MSI acquisition software system was developed using Qt Creator with Linux as the operating system. At the same time, the hardware design and software algorithm are optimized to solve the problems of fast switching of multi-spectral light sources and their compensation of light decay. After experimental testing, the system realizes the functions of transient time-division acquisition of MSI information, adaptive adjustment of the light source, and light decay detection, which have the value of popularization and application.
