【摘要】：数码扫描仪作为一种光、机、电、计算机一体化输入设备，应用于高端艺术品数字化复制保存领域，具有便携式、高精度、高质量的特点，有着广泛的市场的需求。本文首先提出了一种新型的便携式可调分辨率的数码扫描仪设计思想，在新的设计中，采用线阵CCD作为图像采集传感器，，并以GL847控制器为核心设计出高性能的图像采集系统，利用可调焦数码镜头将光线采集到CCD图像传感器表面，并配合电机控制装置的稳定工作，完成一幅图像的采集过程。接着对以GL847控制器为核心的底层控制模块的各个内部模块进行了详细的分析。然后介绍了以MFC基础类库为技术基础的上层应用软件需求分析以及工作流程。最后介绍了利用动态链接库作为上下层通信的桥梁，有效的节省开发时间，并提高程序的可复用性。整个系统采用分层设计思想，有效地实现了“高内聚、低耦合”的设计理念。
[Abstract]:As a kind of integrated input equipment of light, machine, electricity and computer, digital scanner is applied in the field of digital reproduction and preservation of high-end art. It has the characteristics of portable, high precision and high quality, and has wide market demand. In this paper, a new kind of portable digital scanner with adjustable resolution is proposed. In the new design, the linear CCD is used as the image acquisition sensor, and the high performance image acquisition system is designed with the GL847 controller as the core. The light is collected to the surface of the CCD image sensor by using the zoom digital lens, and the motor control device works stably. Then, each internal module of the bottom control module with GL847 controller as the core is analyzed in detail. Then, the requirement of the upper layer application software based on the MFC basic class library is introduced. Finally, the use of dynamic link library as a bridge of communication between the upper and lower layers is introduced. It can save the development time and improve the reusability of the program. The whole system adopts the idea of layered design and realizes the design idea of "high cohesion and low coupling" effectively.
