【摘要】：数字相机由于具有高度的灵活性与可靠性,齐全的种类与完善的性能,被广泛的应用在工业,医疗,科研,军事等各个领域,成为大多数系统中的图像输入设备,负责记录及测量等功能。而基于Camera Link接口的数字相机由于具有非常高的传输速率及接口协议简单等优点,在科研领域有着非常广泛的应用；目前绝大多数的Camera Link接口的数字相机都与图像处理部分配合使用,来实现记录和测量功能。在图像处理部分进行开发和调试过程中,常常需要输入已知的确定图像如全黑,彩条,鉴别率靶等,来作为参考的基准图像。目前常使用相机直接对准直光系统配合靶板成像的方式来实现。这种方法存在着使用不便、精度不高等缺点,已不能满足当前系统的需要。因此,迫切需要一种新的方法来将其替代。本文设计了一种基于Camera Link接口的可输出预定数字视频图案的装置,在本文中称为虚拟数字相机(Virtual Digital Camera)。虚拟数字相机可以输出预先通过USB接口传送到虚拟相机内的图像,输出的格式和速率都可以调节。本文分析了国内外该领域的发展状况,并提出了虚拟数字相机(Virtual Digital Camera)的概念,设计了系统的软硬件结构,并调试出了一部样机,从而证明该设计的可行性。并通过实验验证了系统工作正常,使用灵活,可输出任意图像,从而为系统的调试和校准提供了一个理想的解决方案。
[Abstract]:Because of its high flexibility and reliability, complete variety and perfect performance, digital camera has been widely used in many fields such as industry, medical treatment, scientific research, military and so on, and has become the image input equipment in most systems. Responsible for recording and measuring functions. The digital camera based on Camera Link interface has been widely used in the field of scientific research because of its high transmission rate and simple interface protocol. At present, most digital cameras with Camera Link interface are used in conjunction with image processing to realize recording and measuring functions. In the process of image processing development and debugging, it is often necessary to input known deterministic images such as full black, color stripes, discriminant targets and so on, as a reference image. At present, the camera is often used to directly collimate the system with the target plate imaging method to achieve. This method has some disadvantages, such as inconvenient use and low precision, so it can not meet the needs of the current system. Therefore, there is an urgent need for a new method to replace it. This paper designs a device based on Camera Link interface that can output predetermined digital video pattern, which is called virtual digital camera (Virtual Digital Camera). In this paper. The virtual digital camera can output the image which is transmitted to the virtual camera through the USB interface in advance, and the output format and speed can be adjusted. This paper analyzes the development of this field at home and abroad, and puts forward the concept of virtual digital camera (Virtual Digital Camera), designs the hardware and software structure of the system, and debugs a prototype to prove the feasibility of the design. It is proved by experiments that the system works normally, can be used flexibly, and can output arbitrary images, thus providing an ideal solution for the debugging and calibration of the system.
